摘要
A new isopimarane-type diterpene was isolated from the ethanol extract of the aerial parts of Nepeta septemcrenata. Its structure was established as 1 alpha-hydroxy-7 alpha,14 alpha,18-triacetoxy-isopimara-8,15-diene using different spectroscopic techniques (UV, IR, MS and 1 and 2D NMR). In addition, 7-O-methylapigenin was also isolated and identified. Copyright (C) 1997 Elsevier Science Ltd
