摘要：

A phytochemical investigation of the ethanol extract from the barks of Litsea rubescens resulted in the isolation of three new compounds, 3 alpha,7 beta-diacetyl-8 beta-methyloctahydro-4 beta-methyl formate (1), (-)-N-methoxycarbonylorientailine (3), and 9-O-[4-O-acetyl-alpha-L-rhamnopyranosyl-(1 -> 6)-beta-Dglucopyranosyl]-3,4-dimethoxycinnamic acid (5), together with two known compounds, 3 alpha,7 beta-dihydroxy-8 beta-methyloctahydro-4 beta-methyl formate (2) and (-)-orientailine (4). The structures of the three new compounds were elucidated on the basis of 1D, 2D NMR (COSY, HMQC, HMBC, and NOESY), and mass spectral analyses.
