Abstract

India has one of world’s richest medicinal plant heritages. The wealth is not only in terms of the number of unique species documented, but also in terms of the tremendous depth of traditional knowledge for the use of human & livestock health and also for agriculture. The medicinal plant species are used by various ethnic communalities for human and veterinary health care, across the various ecosystems in India. Chitradurga district of Karnataka state at its extreme limits is situated between longitudinal parallels of 76’ 01’ and 77’ 01 east of Greenwich and latitudinal parallels of 13’ 34’ and 15’ 02’ north of equator in the leeward side of the Western Ghats. The topographical and climate diversity of the region has resulted in dry deciduous to thorn scrub forest. The plant diversity of the region is facing a severe depletion due to the continuous loss of forest land, uncontrolled grazing, forest fire, landslides and anthropogenic activities. The medicinal properties shown by different plants are due to the phytochemicals present in them which are the most vital sources for the treatment of destructive diseases by enhancing the immune system by producing specific physiological action on the human body. Flavonoids, tannin, phenolic compounds and alkaloids are the most important bioactive components of plants. At this juncture, conservation and protection of ethno medicinal plants of the region needs top priority. The present investigation is an attempt to survey of Asclepidaceae members for their ethno-medicinal uses to cure various ailments by the ethnic groups which may leads to the discovery of biochemical/ biopharmaceutical compounds.
