Abstract

The use of medicinal plants in the treatment and prevention of diseases is attracting the attention of scientists worldwide. Approximately 2800 plant species are currently used by an estimated about 150,000 indigenous traditional healers in India. The specific part of the plant used for medicinal applications varies from species to species and from one traditional healer to another. This study was carried out to explore and record those plants and plant parts used for treating various human ailments by the traditional healers of the Erumalainayakkanpatti Village in the Periyakulam taluk province, Tamilnadu for medicinal purposes. Ethnobotanical data were collected from 35 traditional healers (26 females and 9 males) in the Erumalainayakkanpatti Village area of Periyakulam taluk by means of a data capture questionnaire focusing on the local names of the medicinal plants, their medicinal uses, the plant parts used, and methods of preparation and of administering treatments to patients. The survey identified 92 medicinal plants from 44 families, used to treat a range of ailments in the Erumalainayakkanpatti Village. The Amaranthaceae,Solanaceae and Fabaceae family was the most commonly used plant family representing 15.9% of all the medicinal plants species recorded by this study, followed by the Poaceae and Euphorbiaceae family at 13.6%. The plant parts most frequently used were the leaves (42.3%), followed by the Fruits (19.5%), Roots (5.4%), Seed (4.3%), whole plant (9.7%), Flowers (5.4%) and others (13.0%). Most of the traditional healers obtained their extracts by boiling the medicinal plants. The rural communities of the Erumalainayakkanpatti Village possess a wealth of information on medicinal plants and their applications. This ethnobotanical survey can help scientists identify for further research those plants whose medicinal properties may be useful in the development of new drugs.

Abstract

An in vitro clonal propagation protocol was evolved for Janakia arayalpathra Joseph & Chandras. - a rare endemic and threatened medicinal plant. Axillary bud explants cultured in Murashig and Skoog medium supplemented with 8μM BAP + 4μM IAA evinced maximum shoot multiplication response than the other combinations. The survival of shoots in root induction medium necessitated the addition of BAP along with IBA. Maximum root induction was observed in medium supplemented with 8μM BAP + 6M IBA. An average of 45 shoots could be produced by three sub cultures within 5 months’ period. Plants were successfully acclimated and established in field conditions. About 60 % of in vitro derived plantlets survived in field conditions.

Key Words: Clonal propagation, Axillary bud culture, Janakia arayalpathra.
