According to the traditional medicinal usage of Sonneratia caseolaris, we tested the extract of S. caseolaris for antioxidant activity using 1,1-diphenyl-2-picrylhydrazyl (DPPH) radical scavenging effect on thin-layer chromatography. Following activity-oriented separation, two flavonoids, luteolin (1) and luteolin 7-O-β-glucoside (2), were isolated. Both of the compounds were found to possess antioxidant activity.
根据海桑的传统药用用途，我们利用1,1-二苯基-2-苦基肼（DPPH）自由基清除作用在薄层色谱上测试了海桑提取物的抗氧化活性。通过活性导向分离，分离出两种黄酮类化合物，木犀草素（1）和木犀草素7-O-β-葡萄糖苷（2）。发现这两种化合物均具有抗氧化活性。
