| Abstract: | The effect of glucan A and phosphatidyllycorine, isolated from Crinum latifolium L. (family Amaryllidaceae) was studied on the rate of degranulation of mast cells of albino rats. Different combinations of glucan A and phosphatidyllycorine (5–20 and 5–10 μg/mL, respectively) in vitro, produced statistically significant protection against Tween 80-induced degranulation, as well as to sensitized mast cells challenged with an antigen (horse serum). The combination (10–20 mg/kg), when administered in vivo, also provided protection against compound 48/80-induced degranulation of mast cells. The findings are appraised in view of the use of the total extract of C. latifolium, for the treatment of allergic disorders in Ayurvedic medicine. |
