高良姜花和果实的化学成分及生物活性

Chemical Constituents and Biological Activities of Flowers and Fruits of Alpinia Officinarum Hance

采用高效液相色谱法(HPLC)测定海南省不同产地的高良姜花和果实乙醇提取物中槲皮素、异鼠李素、高良姜素和山奈素的含量,通过滤纸片琼脂扩散法测定其对白色念珠菌、金黄色葡萄球菌和茄科雷尔氏菌的抑制活性。结果表明,高良姜花中只含有槲皮素,果实中含有槲皮素、高良姜素、山奈素;高良姜花和果的提取物对金黄色葡萄球菌、白色念珠菌和茄科雷尔氏菌均有一定的生长抑制活性。

The quantitative analysis of chemical constituents quercetin,isorhamnetin,galangin and kaempferol of flowers and fruits of Alpiniae officinarum in different localities of Hainan Province was performed with HPLC,and their antimicrobial activities against Canidia albicans,Staphyloccocus aureus and Ralstonia solanacearum were assayed by the filter paper agar diffusion method.The results showed that the flowers of A.officinarum only contained quercetin while the fruits contained quercetin,galangin and kaempferol.The extracts of the flowers and fruits of A.officinarum both had an inhibitory effect on the growth of S.aureus,C.albican and R.solan,a,cearum.
