title: [Antibacterial components from artificially induced dragon's blood of Dracaena cambodiana].
abstract: Ten compounds were isolated from the artificially induced dragon's blood of Dracaena cambodiana by various column chromatographies on silica and sephadex LH-20 gel. Based on spectral analysis of NMR and MS, their structures were identified as 3, 4-dihydroxyallylbenzene (1), 3', 4', 5'-trimethoxycinnamylalcohol (2), pinoresinol (3), (2R)-7, 4'-dihydroxy-8-methylflavane (4), (2R)-7,4'-dihydroxy-5-methoxy-8-methylflavane(5),(2S)-7,3'-dihydroxy-4'-methoxy-8-methylflavane(6) ,(2S)-4',7-dihydroxy-6, 8-dimethylflavane(7), 4,2',4'-trihydroxychalcone(8), 4,4'-dihydroxy-2-methoxydihydrochalcon(9) and Cambodianin E (10). Antibacterial activity assay showed that compounds 1, 4 and 10 have inhibitory effect on Fusarium oxysporum f. sp. cuben, Fusarium oxysporum f. sp. niveum, Fusarium oxysporum f. sp. vasinfectum and Ralstonia solanacearum.
