Description

ZINGIBERACEOUS MEDICINAL AND AROMATIC PLANTSGreen plants synthesise and preserve a variety of biochemical products, many of which are extractable and used as chemical feed stocks or as raw material for various scientific investigations and industrial utilization. Medicinal plants are generally known as “Chemical Goldmines” as they contain natural chemicals, which are acceptable to human and animal systems. All these chemicals cannot be synthesised in laboratories. Many secondary metabolites of plant are commercially important and find use in a number of pharmaceutical compounds. Human beings have been dependent on plants for their health care needs since the beginning of civilistion. Of the 2,50,000 higher plant species on earth, more than 80,000 are medicinal in nature. About 5000 species are extensively used in traditional systems of medicine and are studied in some detail. The Red Data Book of India has 427 entries of endangered species of which 28 are considered extinct, 124 threatened, 81 vulnerable, 100 rare and 34 insufficiently known species (Thomas, 1997). India has one of the richest ethnobotanical traditions in the world with more than 7000 species of plants found in different agro-ecosystems and used by various indigenous systems of medicine and industries. Over 95% of the plants used by the herbal or pharmaceutical industry is collected from wild sources. Given the alarming rate of loss of biodiversity due to other well-known factors alongside the indiscriminate collection of wild medicinal plants, there is a real danger of extinction of many of our medicinal plant species. In the face of serious threat to biodiversity, it is extremely important to take urgent steps to conserve and develop medicinal plant genetic resources alongside their cultural roots in all our diverse agro-ecosystems. Zingiberaceae family constitutes a vital group of rhizomatous medicinal and aromatic plants characterised by the presence of volatile oils and oleoresins of export value. Generally, the rhizomes and fruits are aromatic, tonic and stimulant; occasionally they are nutritive. Some are used as food as they contain starch in large quantities while others yield an astringent and diaphoretic juice. The important genera coming under Zingiberaceae are Curcuma, Kaempferia, Hedychium, Amomum, Zingiber, Alpinia, Elettaria and Costus. In the genus Alpinia, A. galanga is the most important one, which finds varying uses in ayurvedic preparations such as “Rasnadi powder”. Costus speciosus is the only species in the genus Costus that is medicinally important. It is valued very much for its diosgenin content. In Curcuma, C. longa is the most popular one, which has been studied in greater depths already. C. aromatica is used in the treatment of skin diseases and is extensively used in vanishing creams. Kaempferia galanga has become very popular and is identified to have tremendous effect in curing bronchial and gastric diseases. Of late, it is being used in preparations of mouth washes and oral deodorants. K. rotunda is another related crop under this genus which has potential for great exploitation on commercial basis. Systematic Position of Zingiberaceae Family The systematic position of the family Zingiberaceae is as follows. Kingdom : Plantae Sub-kingdom : Phanerogamae Division : Spermatophyta Subdivision : Angiospermae Class : Monocotyledonae Series : Epigynae Order : Scitaminales Family : Zingiberaceae A Botanical Description of the Family Zingiberaceae Zingiberaceous Medicinal and Aromatic Plants are generally herbs, often large, with a pseudostem of convolete leaf-sheaths. Leaves are radial or cauline and usually membranous. Sheaths are generally large, clasping the stem; lamina with a strong central nerve and pinnate close secondary nerves. Petioles are short or nil. Flowers are hermaphrodite, irregular, solitary or spicate, bracts membraneous, bracteoles membranous or nil. Perianth is 2-serrate, superior, outer segments three, calyx free and imbricate or connate in an entire toothed or spathaceous tube. Inner segments are petaloid, connate in a long or short corolla tube, free or adnate to the petaloid staminodes, or 5-perfect with a six imperfect or obsolete. Anthers linear and 2 -celled. Ovary is 3-celled, inferior with many ovules, anatropous and axile. Style is usually slender with 2 short stylodes, crowning the ovary. Stigma is usually entire or sub entire. Fruit is loculicidally a 3-valved capsule, or indehiscent and membranous or fleshy, usually crowned by the remains of the perianth. Seeds are often arillate, albumen floury and embryo small. 2 Zingiberaceae family comprises about 50 genera usually found throughout the warm regions of both hemispheres. Out of these about nine genera are reported to constitute potential medicinal and aromatic plants as listed below. Genus Curcuma Kaempferia Hedychium Amomum Zingiber Alpinia Elettaria Costus Gastrochilus Species C. amada, C. longa, C. zedoaria, C. aromatica K. rotunda, K. galanga H. spicatum, H. coronarium A. subulatum Z. officinale, Z. zerumbet A. galanga, A. calcarata, A. allughas E. cardamomum C. speciosus G. pandurata Biotechnology in Zingiberaceous Plants Mustafa and Hariharan (1998) have developed a new tissue culture method for the large-scale multiplication of Zingiberaceous species. Buds or propagules collected from the underground stems of these plants are sterilized with detergents or suitable sterilizing agents. The sterilized buds are asceptically inoculated in artificial nutrient medium supplied with suitable hormones and are placed under controlled temperature and light. Tissue mass (callus) or multiple buds are induced and subcultured into the media supplied with hormone combination so as to produce in vitro shoots and roots. About 25-30 plantlets are produced per culture tube. The shoots obtained in vitro are transferred to natural outdoor conditions. Plants obtained by this method are free from viruses, fungi and bacteria. They are superior in quality and more plants can be produced with in a shorter period and the progeny is uniform. ALPINIA Importance This plant is cultivated for its rhizome in tropical areas of South and East India. Because of the presence of essential oil, the rhizomes are used in bronchial troubles and as a carminative. It is one of the ingredients of medicated “Pan” used for removing the foul smell of the mouth and getting relief in throat inflammation. In Ayurveda, “Rasna-saptak-kwath” and “Rasna-adikamath” are used as antiinflammatory decoctions. In Unani, it is an ingredient of aphrodisiac preparations, “ Majun Mugawivi ma Mumsik”, “Majun Samagh”, and antispasmodic nervine tonic “Majun Chobchine” and “Lubab Motadil”. It is also used in “Arq Pan” as a cardiac stimulant carminative (Thakur et al, 1989). They are also useful in vitiated conditions of vata and kapha, rheumatoid arthritis, inflammations, stomatopathy, pharyngopathy, cough, asthma, hiccough, dyspepsia, stomachalgia, obesity, diabetes, cephalalgia, tubercular glands and intermittent fevers (Warrier et al, 1993). Charaka includes rasna (Alpinia) in the Vayasthapana Varya, the group of drugs that are capable of maintaining the youthful vigour and strength. The officinal part is the rhizome which forms a major ingredient of preparations like Rasnadi Kasaya, Rasnadi churna, Rasnadi taila, Asvagandharishta, etc (Sivarajan and Balachandran, 1994). The drug stimulates digestion, purifies blood and improves voice (Chunekar, 1982). Botany In most of the publication on Indian Materia Medica, rasna is equated with an orchid Vanda tessellata (Roxb.) Hook ex Don. Syn. Vanda roxbugrhii R.Br. (Kirtikar and Basu, 1988; Vaidya, 1936; Nadkarni, 1954; Chopra et al, 1956; Kurup et al, 1979; Kapoor and Mitra, 1979; Dey, 1980). Some others consider Pluchea lanceolata (Asteraceae) as the real source of rasna (Singh and Chunekar, 1972; Sharma, 1983). This is the rasna of Punjab and Gujarat (Vaidya, 1982). But none of them is taken as the drug source in Kerala. Throughout South India, it is the aromatic rhizomes of Alpinia galanga that is accepted as the source of rasna. As the synonyms elaparni and sugandha suit this plant well, this is believed to be the true rasna by South Indian physicians. Some authors equate this plant with Kulanjana or Sugandhavaca (Nadkarni, 1954; Chopra et al, 1956; Sharma, 1983) giving the Malayalam equivalent of rasna, namely Aratta. Studies on the market samples reveal that two types of rasna are sold in South Indian markets-one with light brown colour and aromatic odour identified as the rhizomes of A. calcarata Rosc. locally called peraratta and the other less aromatic, A.galanga, known as the chittaratha or aratta in vernacular (Nair et al, 1982). The above two species are used as the drug sources in Kerala. 3 1. Alpinia galanga Eng: Greater galangal, Java galangal, Siamese galangal; San:Sugandhamula,Rasna; Hin:Kulainjan; Mal:Aratta, Chittaratha; Tam:Arattai; Guj: Kolinjan; Kan: Dumba-rasmi; Mar: Kosht-Kulinjan; Tel: Pedda-dumparash-tram Alpinia galanga (Linn.) Willd. is a perennial herb, about 2m high with lower portion covered with smooth leaf sheaths. The leaves are broadly lanceolate, 30-60cm long and 10-15cm broad. The flowers are arranged in erect, terminal panicles composed of numerous spreading dichotomous branches each with two to six, pale greenish-white faintly fragrant flowers. Fruits 1.25 cm long, oblong, constricted in the middle or even pear shaped, three sided and deep orange red in colour. Seeds are ash coloured, three angled, finely striated towards the hilum. Both the seeds and rhizomes have pungent aroma (Thakur et al, 1989). The plant is also described by Gamble (1987), Sivarajan and Balachandran (1994), Warrier et al (1993) and Kirtikar and Basu (1987). 2. Alpinia calcarata Mal: Kolinchi. Alpinia calcarata Rosc. is another species of the genus with much medicinal importance. It is shorter in stature but stronger in aroma than Alpinia galanga. It is a perennial herb with non- tuberous root-stock. Stem is slender and 0.6-1.2m high. Leaves are 15-30 x 2.5-5cm; lanceolate, acuminate, green and glossy. Flowers are numerous, large, arranged in dense panicles, 7.5-10cm long, with pubescent rachis and small ovate bracts. Calyx tube is funnel-shaped and 6-8mm long. Corolla segments are 13mm long. Lip is 2.5-3.8cm long, ovate-oblong, sessile, yellow, streaked with purple veins and emarginate. Ovary is densely pubescent with many ovules in each cell. Capsules are globose and red (Kirtikar and Basu, 1987). Developmental studies in A. calcarata show that the placentae intrude into the ovary chamber and fuse at the lower portion of the ovary, leaving the upper portions of the ovary chambers confluent (Mangary and Hamsa, 1991) The botanical description is also done by Sivarajan and Balachandran (1994) and Gamble (1987). 3. Alpinia allughas San: Taraka Hin: Taro Mal: Malayinjikkuva Another species of Alpinia, which has the therapeutic properties, is A. allughas Rosc. It is a stout perennial herb with tuberous, aromatic roots. Leaves are sessile, oblong,-lanceolate, acuminate, cuspidate, glabrate, striate and compressed. Flowers are inodorous, pink, inerect, arranged in dense panicles with pubescent rachis and small ovate cupular bracts. Lip more than 2-5cm long, pink, obovate-cuneate, or suborbicular. Fruit black, thin, globose and irregularly rupturing. Seeds many, small, black and angular (Kirtikar and Basu, 1987). The three species can be distinguished as follows: In A. galanga, flowers are greenish white, lip veined with red. In A. calcarata, flowers are white, lip variegated with red and yellow. In A. allughas, flowers are pink (Gamble, 1987). Agrotechnology Alpinia comes up well in tropical climate. It grows on a wide range of climate and soils. Welldrained hilly areas and places of 1400m high altitude are good for its cultivation. This is commercially propagated vegetatively by rhizomes. The field should be ploughed to a good tilth. All the stones and pebbles should be removed. Organic manures at 10t/ha are applied during land preparation. Seedbeds are prepared with 1m breadth, 2m length and 15cm height. Small pits are made at 25cm spacing above the seedbeds and 5cm long rhizomes are planted. Seedbeds are covered with dried leaves. It is irrigated immediately after planting. Regular weeding is needed during the initial stages of crop growth. This is cultivated also as an intercrop in coconut or rubber plantations. Rhizomes are dug out after cutting the top portions when the crop reaches 1.5-2 years of maturity. The average yield is 10-15 tonnes of fresh rhizomes/ha and the driage is 2530%. The collected rhizomes are washed and cut into pieces of 5cm long and dried in sun for 4 days before sale (Prasad and Joseph, 1997). 5%). caryophyllenol I and II.9%) as major compounds. disinfectant.18 monoterpenes were isolated of which α-pinene (22. comes to normal in a short time.OAc-eugenol-OAc. ceremonial colour and as a magical symbol.
