To identify the active constituents with α-glucosidase inhibitory activities in Sabia parviflora, three new compounds, namely, sabiaparviflora A-C (1, 2 and 8), and seven known compounds were isolated from the plant by repeated column chromatography. The structures of the new compounds were identified by extensive application of spectroscopic methods, including H NMR, C NMR, IR and HR-ESI-MS. All compounds, except for compounds 3-5, 9 and 10 were isolated for the first time from S. parviflora. Their α-glucosidase inhibitory activities were evaluated for the first time by the PNPG method. Three compounds (1, 7 and 10) exhibited marked activities, with IC values ranging from 104 to 324 μM, and their structure-activity relationship is preliminarily discussed herein.
为了从细梗香草(Sabia parviflora)中鉴定出具有α-葡萄糖苷酶抑制活性的活性成分,通过反复的柱层析从该植物中分离得到了三个新化合物,分别为 sabiaparviflora A-C(1、2 和 8),以及七个已知化合物。通过广泛应用包括 H NMR、C NMR、IR 和 HR-ESI-MS 在内的光谱方法,确定了新化合物的结构。除了化合物 3-5、9 和 10 之外,所有化合物均为首次从细梗香草中分离得到。首次通过 PNPG 法评估了它们的α-葡萄糖苷酶抑制活性。三个化合物(1、7 和 10)表现出显著的活性,IC 值范围为 104-324 μM,初步讨论了它们的构效关系。
