Publication date: October 2019Source: Biochemical Systematics and Ecology, Volume 86Author(s): Yang Yan, Chuanhai Wu, Hui Zhou, Xiaoye Feng, Yan-Fang LiAbstractOne new flavonol glycoside (1) and nine known compounds (2–10) were obtained from the n-BuOH soluble fraction of the whole plants of Spiranthes sinensis. The structure of compound 1 was elucidated based on the combination of spectroscopic (1H-NMR, 13C-NMR, HSQC, and HMBC as well as HR-ESI-MS) and chemical methods. The occurrences of eight compounds (2-9) in this genus were firstly reported while five of them (2–6) were obtained from Orchidaceae for the first time. Furthermore, the chemotaxonomic significance of these compounds was discussed.
