摘　　要：A new compound, Cochinchin (1), together with 7,4'-dihydroxyflavone (2), 7-hydroxy-4'-methoxyflavane (3), 7-hydroxy-3-(4-hydroxybenzyl)chroman (4), 4'-hydroxy-2,4-dimethoxydihydrochalcone (5) and 4'-hydroxy-2,4,6- trimethoxydihydrochalcone (6) was isolated from the resin (trivial name, “dragon’s blood”) of Dracaena cochin- chinensis (Lour.) S. C. Chen. The structure of 1 was elucidated on the basis of spectroscopic data as (2,3-trans)-6-allyl-2-(3,5-dimethoxyphenyl)-3-(4-hydroxyphenyl)-2,3-dihydrobenzo[1,4]dioxin which is a natural product possessing a new framework.A new compound, Cochinchin (1), together with 7,4'-dihydroxyflavone (2), 7-hydroxy-4'-methoxyflavane (3), 7-hydroxy-3-(4-hydroxybenzyl)chroman (4), 4'-hydroxy-2,4-dimethoxydihydrochalcone (5) and 4'-hydroxy-2,4,6- trimethoxydihydrochalcone (6) was isolated from the resin (trivial name, “dragon’s blood”) of Dracaena cochin- chinensis (Lour.)
