The present study was conducted to compare leaf extracts of and . Plant extracts were obtained by sequential extraction with 50% and 100% methanol using the pressurized liquid extraction method. General comparative analysis of Yucca extracts was performed by 2 D-NMR. The presence of various biologically active components in the extracts was shown, among which steroid saponins predominate. The use of LC-MS and LC-HRMS methods with electrospray ionization made it possible to conduct a comparative analysis of Yucca steroidal saponins. The 33 steroidal saponins of various structures were found. The presence of three characteristic saponins in all Yucca species was shown: yuccaloeside C, yuccaloeside E and yuccaloeside B. The results obtained can be used to control the quality of plant materials and products.
本研究旨在比较 和 的叶提取物。使用加压液体萃取法，用 50%和 100%甲醇进行顺序提取，获得植物提取物。通过二维 NMR 对丝兰提取物进行了一般比较分析。结果表明，提取物中存在各种具有生物活性的成分，其中甾体皂苷占主导地位。使用 LC-MS 和 LC-HRMS 方法结合电喷雾电离，对丝兰甾体皂苷进行了比较分析。发现了 33 种具有各种结构的甾体皂苷。结果表明，所有丝兰物种中都存在三种特征皂苷：丝兰皂素 C、丝兰皂素 E 和丝兰皂素 B。所得结果可用于控制植物材料和产品的质量。
