From the chloroform extract of the aerial parts of Salvia xanthocheila, one new triterpene, together with two known diterpenes, two known flavonoids and a phytosterol was isolated. On the basis of comprehensive spectroscopic analyses, including electron ionisation mass spectra, ¹H-NMR, ¹³C-NMR, 1-D nuclear Overhauser effect, distortionless enchancement by polarisation transfer, H,H correlation spectroscopy, heteronuclear multiple quantum coherence, rotating frame Overhauser enhancement spectroscopy spectra and comparison with spectral data of known compounds, the structure of new compounds was established as 1β,3β-dihydroxy-olean-9(11),12-dienyl (1). The five known compounds (2-6) were 7α-acetoxyroyleanone, taxodione, salvigenin, apigenin-7,4'-dimethyl ether and β-sitosterol, respectively. These known structures are isolated from the aerial parts of S. xanthocheila for the first time.
从黄花香薷地上部分的氯仿提取物中分离得到一种新的三萜，以及两种已知的二萜、两种已知的黄酮类化合物和一种植物甾醇。基于包括电子电离质谱、1H-NMR、13C-NMR、1-D 核 Overhauser 效应、极化转移无失真增强、H,H 相关光谱、异核多量子相干、旋转框架 Overhauser 增强光谱谱和与已知化合物光谱数据的比较，综合光谱分析，新化合物的结构被确定为 1β,3β-二羟基-齐墩烷-9(11),12-二烯基(1)。这五个已知的化合物（2-6）分别是 7α-乙酰氧基罗勒酮、紫杉酮、 salvigenin、apigenin-7,4'-二甲醚和β-谷甾醇。这些已知结构是首次从黄花香薷的地上部分中分离得到的。
