| 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-dirnethoxydihydrochalcone (5) and 4‘-hydroxy-2,4,6-trimethoxydihydrochalcone (6) was isolated from the resin (trivial name, “dragon‘s blood“) of Dracaena cochinchinensis (Lour.) S. C. Chert. 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-dihydrobenzo1,4]dioxin which is a natural product possessing a new framework.

| Abstract: | 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 cochinchinensis (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‐dihydrobenzo1,4]dioxin which is a natural product possessing a new framework. |
