Two new diarylheptanoids (1, 2) and seven new diarylheptanoid glucosides (3-9) were isolated from the rhizomes of Tacca chantrieri. Their structures were determined by spectroscopic analysis, including 2D NMR data, and the results of hydrolytic cleavage. The absolute configurations of the 3,5-dihydroxyheptane moieties of the new diarylheptanoids were determined to be 3R and 5R by the application of
从番茄根茎中分离出两个新的二芳基庚糖苷(1,2)和七个新的二芳基庚糖苷(3-9)。通过光谱分析确定其结构,包括2D NMR数据和水解裂解结果。通过将CD激子手性方法应用于相应的3,5-双-对-溴苯甲酰基衍生物,确定了新的二芳基庚烷的3,5-二羟基庚烷部分的绝对构型为3R和5R。据报道,分离的化合物和一些衍生物对HL-60人早幼粒细胞白血病细胞,HSC-2人口腔鳞状细胞癌和正常人牙龈成纤维细胞(HGF)的细胞毒活性。
