The medicinal plant Gymnema sylvestre R. Br. is known for its antidiabetic potential. Preliminary phytochemical screening of stem and leaf samples of the herb showed positive testforflavonoids, hydrolysable tannins, phenols, saponins, sterols and terpanoids. The ash value is below the prescribed limit according to Ayurvedic Pharmacopeia. Antimicrobial activity was checked using agar well diffusion method. Water, methanoland ethanol extracts showed activity against Staphylococcus aureus. Bacillus subtilis is sensitive to hydroalcoholic and ethanolic extracts. The gram negative bacteria were resistant to the extracts. The antioxidant potential was assessed by DPPH assay method. The results provide evidence that Gymnema sylvestre leaf extract might indeed be potential source of free radical scavenger.

Inula racemosa Hook. f. (Asteraceae) is widely used in traditional medicine in India and Tibet as well as in drug industries for its antispasmodic, anti-asthmatic and digestive properties and as veterinary medicine also. It is commonly known as pushkaramoola, a stout herb mostly found in western Himalaya up to 2600 m. The great sage Charaka has characterized it as hikka magrahana (stops hiccups) and svasahara (helpful in asthma). Coffea travancorensis Wight & Arn., belonging to the family Rubiaceae is often sold throughout Kerala market under the name Pushkaramulla. People in Kerala use the roots of Pushkaramulla instead of Pushkaramoola, the former is an adulterant. In order to ensure the use of only genuine and uniform material in preparation of herbal formulation, work on standardization was carried out. Macroscopical and microscopical characteristics were worked out to identify the diagnostic features of the plant. Physicochemical and ultra-violet analysis helped in the identification of genuine drug and also contributed towards establishing pharmacopoeial standards.
