Publication date: October 2019Source: Biochemical Systematics and Ecology, Volume 86Author(s): Jin-Ling Zhang, Shang-Chun Song, Ji-Cheng Liu, Peng-Hui Ni, Lei Liu, Yu-Kun Ma, Yu Sun, Qi Liu, Li-Na GuoAbstractThis work described the isolation and characterization of seven compounds from Dictamnus dasycarpus Turcz., including one new ester, (2R)-4-(2,2-dimethyl-5-oxotetrahydrofuran-3-yl)-2-hydroxypent-3-anoic acid ethyl ester (1); and six known glycosides (2–7). The structure of compound 1 was elucidated on the basis of extensive spectral analyses, including IR, HR-ESIMS, 1D and 2D NMR (NOESY, HMBC and HSQC). All these compounds were described here for the first time from the genus Dictamnus. Moreover, the results provide further information about the diversity of compounds in the genus Dictamnus.
