摘要
从无毛狭叶香茶菜（Ｉｓｏｄｏｎａｎｇｕｓｔｉｆｏｌｉｕｓｖａｒ．ｇｌａｂｒｅｓｃｅｎｓＨ．Ｗ．Ｌｉ）中分离得到４个已知二萜化合物：７－乙酰基－鲁山冬凌草甲素，鲁山冬凌草甲素、乙素和紫萼香茶菜甲素，经二维核磁共振波谱（ＺＤ－ＮＭＲ）解析表明，它们的结构分别由先前报道的５，６，７和８应修订为结构１，２，３和４。
Four known diterpenoids 7-acetyl - lushanrubescensin A, Lushanrubescensin A and B, and rabdoforrestin A have also been isolated from Isodon angustdolius var. glabrescens, and their structures have revised to 1, 2, 3, and 4 from the structures 5, 6, 7 and & reported previously by the spectral analysis, especially on the basis of 2D NMR data in this paper.
