Title: Preliminary phytochemical analysis of bark of Ficus racemosa Linn and antibacterial activity of its bark oil. Authors: Unnikrishnan, Neena; Somanath, Manu; C.I., Jolly; D., Sheela Abstract: The leaves, fruits and bark of Ficus racemosa Linn, are used in the Ayurveda for the treatment of dysentery, skin diseases, diabetes, asthma and inflammatory swellings. Phytochemical screening of the bark showed positive tests for sterols, saponins and tannins. Agar well diffusion method proved that methanolic extracts of the oil prepared from the bark possess good antibacterial activity against the tested Gram positive strains and has shown intermediate action against tested Gram negative strains.

Title: Preliminary phytochemical analysis of bark of Ficus bengalensis Linn and antibacterial activity of its bark oil. Authors: Unnikrishnan, Neena; Mathappan, Rinku; Somanath, Manu; D., Sheela Abstract: The bark and aerial roots and leaf buds of Ficus bengalensis Linn are used in the ayurveda for the treatment of dysentery , skin diseases, diabetes, piles,ulcers, and inflammatory swellings. Phytochemical screening of the bark showed positive tests for sterols, flavonoids, glycosides, saponins and tannins. Agar well diffusion method proved that methanolic extracts of the oil prepared from the bark posses good antibacterial activity against the tested Gram negative strain Salmonella typhymurium and has shown intermediate action against tested few Gram positive and Gram negative strains.

Title: Antioxidant activity and polyphenol content of seven medicinal plants of Asclepiadaceae - a comparative study Authors: Irimpan, Meena Thomas; C.I., Jolly; D., Sheela Abstract: Seven medicinal plants of the family Asclepiadaceae were characterised for their free radical scavenging activity, total polyphenol and flavonoid contents. Antioxidant activity was determined by DPPH (1, 1-diphenyl-2-picryl- hydrazyl) assay method.There was direct correlation between polyphenol content and antioxidant activity (correlation coefficient = 0.6557). IC50, value and total flavonoid content were strongly correlated (correlation coefficient R2 = 0.8337).These plants represent promising sources of natural antioxidants and these findings give scientific bases to their ethno pharmacological uses.

Title: Study on achene morphology of five species Of Spilanthes jacq. (Heliantheae) Compositae from South India Authors: Sr.Avita; D., Sheela Abstract: Achene morphology of five species Spilanthes Jacq. is investigated by light microscopy and scanning electron microscopy Characters studied are highly useful as a taxonomic tool for delimiting the taxa, both at generic and species level. Based on the characters studied an artificial key for the closely related species of Spilanthes Jacq. is provided.
