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.
本研究采用多种色谱技术从白及（兰科）块茎中分离出17种化合物。根据其理化性质和光谱分析确定了它们的结构。其中，分离并鉴定出两种新的2 - 异丁基苹果酸酯，命名为白及苹果酸酯A（1）和B（2），以及其他15种已知化合物（3 - 17）。此外，化合物3、4和8首次从该植物中分离得到。
