Abstract From the acetone extract of the root bark of Ventilago maderaspatana eight new benzisochromanquinones; ventiloquinones A, B, C, D, E, F, G and H, have been isolated. Ventiloquinones I, J and K are three more new benzisochromanquinones isolated from the root bark of V. calyculata . The majority are 3,4,5,10-tetrahydro- cis -1,3-dimethyl-1H-naphtho[2,3-c]pyran-5,10-quinones related to eleutherin
摘要 从马德拉斯帕塔纳风草根皮丙酮提取物中提取出八种新的苯并异色满醌;已分离出ventiloquinones A、B、C、D、E、F、G和H。Ventiloquinones I、J 和 K 是从 V. calyculata 的根皮中分离出的另外三种新的苯并异色满醌。大多数是与eleutherin相关的3,4,5,10-四氢-顺式-1,3-二甲基-1H-萘并[2,3-c]吡喃-5,10-醌,但F、H、I、J和 K 是与万替拉酮相关的 6,9-醌。
