Adaptogenic Activity of Glyco-Peptido-Lipid Fraction from the Alcoholic Extract of Trichopus Zeylanicus Gaerten (Part II)‪.‬

Abstract Anti-stress activity was carried out on glyco-peptido-lipid (AF) fraction from the alcoholic extract of Trichopus zeylanicus Gaerten and demonstrated against a battery of tests in rats and mice. AF exhibited significant anti-stress activity in dose-related manners in all the parameters studied against different models used to induce non-specific stress viz physical and chemically. The major parameters studied were immobilization induced gastric ulceration, adjuvant-induced trauma (Stress); humoral antibody synthesis in normal and immuno-suppressed mice and delayed type of hypersensitivity (DTH) reaction, chemically stress-induced alteration in hepatic function and anti-oxidant activity. The extract of Withania somnifera root (a commercial preparation available locally, Dabur India ltd.) was used to compare the results. In the safety evaluation study the maximum tolerance dose (MTD) and oral L[D.sub.50] were found to be more than 3000 mg/kg, with no signs of abnormalities or any mortality observed for 15 days period under observation after single dose of drug administration. Feeding behaviour and fecal output were normal.
