Abstract
The present paper deals with the physicochemical and phytochemical examination of seventy-six medicinal plants belonging to thirty-six dicot and six monocot families. These are used in indigenous system of medicine as well as local inhabitants either as single drugs or in combination, for the cure of various ailments. In physicochemical study, the parameters such as moisture content,pH (1% aqueous), total ash, acid insoluble ash, water-soluble extractive and alcohol soluble extractive were carried out. The preliminary phytochemical study was done for the detection of secondary metabolites such as alkaloid, flavonoid, glycoside, phenol, saponin, resin, steroid and tannin. The preliminary phytochemical study revealed the presence of alkaloid and saponin in 68.4%; flavonoid in 44.7%; glycoside, phenol and steroid in 72.37%; resin in 60.5% and tannin in 71% of selected medicinal plants.
Highlights
Indian Ayurvedic Pharmacopoeia recorded more than 300 medicinal plants that are in common use in indigenous system of medicine
In the present investigation out of the selected 76 plants, 63 plants are covered in the Ayurvedic Pharmacopoeia but physicochemical test limits are provided only for total ash, acid insoluble ash, water soluble extractive and alcohol soluble extractive
A slight variation in physicochemical results was found in 46 plants of present study with that of Ayurvedic Pharmacopoeial standard values
Summary
Indian Ayurvedic Pharmacopoeia recorded more than 300 medicinal plants that are in common use in indigenous system of medicine. Medak district is one of the 10 districts of Telangana region of Andhra Pradesh has forests, which are of the southern tropical dry deciduous type account for 9.9% of the total geographical area. It lies between 17o 27’ and 18o 18’ Northern latitude and 77o 28’ and 79o 10’ of Eastern longitude. In view of the above facts and growing interest on plant sources for evolution of therapeutic agents, the present investigation of physico-chemical and phytochemical study of seventy-six medicinal plants belonging to thirty-six dicot and six monocot families has been taken up to determine the quality of raw drugs
