Abstract
Two new iridoid glucosides with 3,4-dihydrocatalpol skeleton, piscrosides A (1) and B (2) together with nine known iridoid glucosides and three known cucurbitacin glucosides, were isolated from the stems of Picrorhiza scrophulariiflora. Their structures were established by MS, 1H NMR, 13C NMR and 2D NMR methods (including HSQC, HMBC and NOESY experiments).
摘要
从胡黄连的茎中分离出两种具有3,4-二氢梓醇骨架的新环烯醚萜苷，即胡黄连苷A（1）和B（2），以及九种已知的环烯醚萜苷和三种已知的葫芦素苷。通过质谱、1H核磁共振、13C核磁共振和二维核磁共振方法（包括异核单量子相干、异核多键相关和核Overhauser效应光谱实验）确定了它们的结构。
