The dried flowers from Aloe vera (L.) Burm. f. (Aloe barbadensis Mill.) (Asphodelaceae) were analysed by means of HPLC-DAD and HPLC-MS/MS, verifying chlorogenic, caffeic, 5-P-coumaroylquinic, caffeoylshikimic, 5-feruloylquinic, 5-P-CIS-coumaroylquinic, P-coumaric and ferulic acid as well as luteolin, apigenin, quercetin, kaempferol, isoorientin, isovitexin and their 7-O-glucosides, saponarin and lutonarin. On searching for anthranoids in the flower extract, aloe-emodin as well as the glycosylchromone aloeresin B could be identified. Aloin A and B, the laxative principle of the drug Curaçao-Aloes, are not accumulated in the dried flowers. The polyphenol content of three different batches was 0.73 - 1.01% (+/- 0.05%) and the flavonoid content 0.24 - 0.34% (+/- 0.01%). The hydrophilic antioxidative capacity amounted to 85.7 - 94.9 (+/- 0.5) micromol TEAC/g dried Aloe vera flower and was directly correlated with the polyphenol and flavonoid contents.
采用高效液相色谱 - 二极管阵列检测法（HPLC - DAD）和高效液相色谱 - 串联质谱法（HPLC - MS/MS）对库拉索芦荟（学名：Aloe vera (L.) Burm. f.，又称巴巴多斯芦荟，百合科）的干花进行分析，验证了其中含有绿原酸、咖啡酸、5 - 对香豆酰奎尼酸、咖啡酰莽草酸、5 - 阿魏酰奎尼酸、5 - 对 - 顺 - 香豆酰奎尼酸、对香豆酸和阿魏酸，以及木犀草素、芹菜素、槲皮素、山奈酚、异荭草素、异牡荆素及其7 - O - 葡萄糖苷、皂草苷和卢托那林。在花提取物中寻找蒽类化合物时，鉴定出芦荟大黄素以及糖基色酮芦荟树脂B。作为药物库拉索芦荟泻药成分的芦荟苷A和B，在干花中并未积累。三个不同批次的多酚含量为0.73 - 1.01%（±0.05%），黄酮含量为0.24 - 0.34%（±0.01%）。亲水性抗氧化能力为85.7 - 94.9（±0.5）微摩尔TEAC/克库拉索芦荟干花，且与多酚和黄酮含量直接相关。
