The antifungal effect of aqueous extracts of four plant species viz; Azadaracta indica A. Juss., Datura metel L. var. quinquecuspida Torr., Ocimum sanctum L. and Parthenium hysterophorus L. was determined in vitro study. It was found that all the plant extracts at 40% concentration were effective in reducing the mycelial growth of F. oxysporum f. sp. ciceri. Among these plants extracts, A. indi...

Study of the syntype of Larinioides subinermis, a species known from Ethiopia only, revealed that it actually belongs to Singafrotypa Benoit, 1962. We redescribe Singafrotypa subinermis (Caporiacco, 1940), comb. n., and provide a key to females of four species belonging to Singafrotypa. A distribution map for all species is provided.

The stability of andrographolide, the major active diterpene lactone from Andrographis paniculata (BURM. f.) WALL. ex NEES., was determined to show that, while crystalline andrographolide was highly stable even at 70 degrees C (75% relative humidity) over a period of 3 months, its amorphous phase degraded promptly. Heat-accelerated conditions revealed second-order kinetics of the decomposition ...
