摘要
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.
