| 2 | Isolation and characterization of two new 2-isobutylmalates from Bletilla striata显示文摘The present study isolated 17 compounds from the tubers of Bletilla striata(Orchidaceae), using various chromatographic techniques. Their structures were identified based on their physical-chemical properties and spectroscopic analyses. Among them, two new 2-isobutylmalates, named bletimalates A(1) and B(2), together with other fifteen known compounds(3-17), were isolated and identified. Additionally, compounds 3, 4, and 8 were isolated from this plant for the first time. | GUAN Huan-Yu YAN Yan WANG Yong-Lin WANG Ai-Min LIU Jun-Hong HE Xun LI Yong-Jun HUANG Yong LIAO Shang-Gao | 2016 | Chinese Journal of Natural Medicines2016，14，11： | 6 |
