Abstract

The present study was aimed to characterize the Antifungal principles in methanol extract of tea ( Camellia oleifera ) seed pomace. Totally, two Flavonoids, camelliasides A (1) and B (2), and one saponin mixture composed of camelliasaponin B(1) (3) were identified from the methanol extract. These constituents were tested for their ability to reduce the Infection of cabbage seedlings by Rhizoctonia solani Kuhn AG-4 and to inhibit growth of the pathogen on potato dextrose agar plates. The saponin mixture is a potential candidate as a new plant-derived pesticide to control Rhizoctonia damping-off of vegetable seedlings.
