材料和方法 一般实验程序 旋光度在 JASCO P-1020 数字旋光计（JASCO，东京，日本）上获得。紫外光谱在 Beckmen DU 640 分光光度计（Beckman Coulter，北京，中国）上记录。红外光谱是在 Nicolet Nexus 470 分光光度计（Thermo Scientific，北京，中国）上在 KBr 盘中获取的。使用四甲基硅烷作为内标，在 JEOL JNM-ECP 600 光谱仪（JEOL Ltd，北京，中国）上记录 1D 和 2D-NMR 光谱，并将化学位移记录为 d 值。电喷雾电离质谱在 Q-Tof Ultima Global GAA076 LC 质谱仪（Waters Asia, Ltd, Singapore）上测量。半制备型 HPLC 在配备 SPD-M10A vp 二极管阵列检测器的 SHIMAD-ZU LC-6AD 液相色谱仪（均来自中国北京岛津国际贸易有限公司）上进行。
MATERIALS AND METHODS General experimental procedures Optical rotations were obtained on a JASCO P-1020 digital polarimeter (JASCO, Tokyo, Japan). UV spectra were recorded on a Beckmen DU 640 spectrophotometer (Beckman Coulter, Beijing, China). IR spectra were taken on a Nicolet Nexus 470 spectrophotometer (Thermo Scientific, Beijing, China) in KBr disks. 1D-and 2D-NMR spectra were recorded on a JEOL JNM-ECP 600 spectrometer (JEOL Ltd, Beijing, China) using tetramethylsilane as the internal standard, and chemical shifts were recorded as d-values. Electrospray ionization mass spectrometry was measured on a Q-Tof Ultima Global GAA076 LC mass spectrometer (Waters Asia, Ltd, Singapore). Semi-preparative HPLC was performed on a SHIMAD-ZU LC-6AD liquid chromatograph with an SPD-M10A vp diode array detector (both from Shimadzu International Trading Co. Ltd, Beijing, China).
