One new triterpenoid olean-18-ene-1β, 2α, 3β-triol (1) along with four known compounds were isolated from the chloroform extract of the aerial part of Salvia atropatana Bunge. The known compounds were two flavonoids, 5-hydroxy-7,4'-dimethoxyflavone (2) and 5-hydroxy-6,7,4'-trimethoxyflavone (3), an abietane-type diterpene namely taxodione (4) and a phytosterol namely γ -sitosterol (5). The structure of (1) was elucidated by comprehensive spectroscopic analysis including electron ionization-mass spectra (EI-MS), (1)H NMR, (13)C NMR, distortionless enhancement by polarization transfer (DEPT), H,H correlation spectroscopy (COSY), heteronuclear multiple quantum coherence (HMQC) and heteronuclear multiple bond correlation (HMBC). The structure of known compounds 2-5 were identified by comparison of their spectral data with those reported in the literature.
从黄花紫堇（Salvia atropatana Bunge）地上部分的氯仿提取物中分离得到一种新的三萜齐墩果-18-烯-1β,2α,3β-三醇（1）以及四种已知化合物。已知化合物为两种黄酮类化合物，5-羟基-7,4'-二甲氧基黄酮（2）和 5-羟基-6,7,4'-三甲氧基黄酮（3），一种枞烷型二萜即紫杉醇（4）和一种植物甾醇即γ-谷甾醇（5）。（1）的结构通过综合光谱分析（包括电子电离质谱（EI-MS）、1H NMR、13C NMR、无畸变极化转移增强（DEPT）、H,H 相关谱（COSY）、异核多量子相干（HMQC）和异核多键相关（HMBC））确定。通过与文献报道的光谱数据进行比较，确定了已知化合物 2-5 的结构。
