Four new iridoid glycosides, kankanosides A (1), B (2), C (3), and D (4), a chlorinated iridoid, kankanol (5), and an acyclic monoterpene glycoside, kankanoside E (6), were isolated from the methanolic extract of dried stems of Cistanche tubulosa (SCHRENK) R. WIGHT (Orobanchaceae) together with 16 known compounds. The structures of these new compounds (1-6) were determined on the basis of the chemical
分离出四个新的鸢尾苷苷,kankanosides A(1),B(2),C(3)和D(4),氯化的鸢尾酮,kankanol(5)和无环单萜苷,kankanoside E(6)。从肉of蓉肉干(SCHRENK)R. WIGHT(Orobanchaceae)的甲醇提取物中提取,还有16种已知化合物。这些新化合物(1-6)的结构是根据化学和物理化学证据确定的。
