Abstract

Phytochemical investigation of the whole plant of Dicranostigma leptopodum (Maxim) Fedde led to the isolation of a new hopane triterpene, dicranostigmone (1), and a known compound, erythrodiol-3-O-palmitate (2). The structure of the new compound (1) was elucidated by various spectroscopic methods including 2D NMR techniques (gCOSY, HMQC, HMBC, NOESY), HR-ESI-MS, and X-ray.

摘要

对秃疮花（Dicranostigma leptopodum (Maxim) Fedde）全株进行植物化学研究，分离得到一个新的藿烷型三萜化合物——秃疮花酮（1）和一个已知化合物——赤藓醇-3-O-棕榈酸酯（2）。通过多种光谱方法，包括二维核磁共振技术（gCOSY、HMQC、HMBC、NOESY）、高分辨电喷雾电离质谱以及X射线单晶衍射对新化合物（1）的结构进行了确证。
