Investigation of the EtOH extract of the rhizomes of Curcuma longa led to the isolation of two new sesquiterpenes, 2-methoxy-5-hydroxybisabola-3,10-diene-9-one (1) and 2,8-epoxy-5-hydroxybisabola-3,10-diene-9-one (2), one new monoterpene, 2-(2,5-dihydroxy-4-methylcyclohex-3-enyl)propanoic acid (3), together with five known sesquiterpenes (4-8). Among the known compounds, bisacurone A (5) and 4-methylene-5-hydroxybisabola-2,10-diene-9-one (6) were isolated from C. longa and genus Curcuma for the first time, respectively. Their structures were established on the basis of various spectroscopic analyses including HR-ESI-MS, 1D and 2D NMR, IR spectra, and by comparison of their spectral data with those of related compounds.
对姜黄根茎的乙醇提取物进行研究，从中分离出两种新的倍半萜，即2-甲氧基-5-羟基双环[3.1.1]庚-3,10-二烯-9-酮（1）和2,8-环氧-5-羟基双环[3.1.1]庚-3,10-二烯-9-酮（2），一种新的单萜，2-(2,5-二羟基-4-甲基环己-3-烯基)丙酸（3）以及五种已知的倍半萜（4-8）。在这些已知化合物中，双莪术酮A（5）和4-亚甲基-5-羟基双环[3.1.1]庚-2,10-二烯-9-酮（6）分别首次从姜黄和姜黄属植物中分离得到。它们的结构是基于包括高分辨电喷雾电离质谱（HR-ESI-MS）、一维和二维核磁共振（1D和2D NMR）、红外光谱（IR）等多种光谱分析，并通过将其光谱数据与相关化合物的数据进行比较而确定的。
