Abstract

Tagar (Valeriana wallichii) belongs to family Valerianaceae. It is known for its various medicinal, cultural and ethno-botanical uses. This is a herb which is used in healing many nervous and other physiological problems. Due to great market potential of the plant, it is harvested in uncontrolled way which is causing the decline of the herb from its natural habitat. Presently, its status in nature is endangered thus there is a need for its in-situ as well as ex-situ conservation and propagation. Hence the present study was conducted by putting different trials with different media to develop techniques for appropriate harvesting and cultivation practices for sustainable utilization of this species.

Abstract

Analysis of two medicinal plants, Andrographis paniculata (Andrographolide) and Oroxylum indicum (mixture of oroxylin A & chrysin) content was carried out under different fertilizer treatments and at different physiological stages of plants. Total ash, water-soluble ash, acid insoluble ash, alcohol soluble extractives and water-soluble extractives for the above plant species were estimated alongwith thin layer chromatography examination. Maximum andrographolide content of 2.0% was found in 120 days old plants and among the treatments given to plants, the chemical fertilizer treatment influenced the Andrographolide, alcohol soluble extractive and water-soluble extractive. In case of Oroxylum indicum, all other evaluated compounds other than oroxylin-A and chrysin content were found to be almost similar whereas oroxylin-A and chrysin content was found maximum in mature tree ischolar_main bark i.e. 0.7%. The results of present study show that fertilizer treatments given to plants and time of harvesting affect the chemical constituents of plants.
