Our phytochemical study on the stem bark of Garcinia mangostana has led to the discovery of a new furanoxanthone, mangaxanthone A (1), together with five known analogs. The five known analogs that were isolated are α-mangostin (2), β-mangostin (3), cowagarcinone B (4), and dulcisxanthone F (5). The structural elucidations of these compounds were carried out by interpreting their spectroscopic data, mainly 1D and 2D NMR spectra and MS.
我们对山竹茎皮进行的植物化学研究发现了一种新的呋喃氧杂蒽酮——山竹氧杂蒽酮A（1），以及五个已知类似物。分离得到的五个已知类似物分别是α-倒捻子素（2）、β-倒捻子素（3）、柯瓦加西酮B（4）和甜黄烷酮F（5）。这些化合物的结构解析是通过解读它们的光谱数据来进行的，主要是一维和二维核磁共振谱以及质谱。
