摘　　要：为了筛选具有抗氧化性的热带花卉,对海南师范大学校园中的12种花卉的鲜花和干花的水提取物、50%乙醇提取物和70%丙酮提取物进行清除DPPH的实验,结果表明:紫薇、干凤凰花、干洋金凤、大叶龙船花卉和干小叶龙船花卉的抗氧化效果最好.This paper reported the antioxidation activities of the extracts from 12 kinds of tropical flowers from tropic plants on Hainan Normal University campus by means of scavenging the DPPH radical. The extracts were prepared by using water, 50% ethnol and 70% acetone as solvents respectively. The flowers of Ixora chinensis Lain, Delonix regia, Casalpinia pulcherrima, Lagetstroemia speciosa and lxora will iamsii cv. Sunkist have been proved to be best antioxidants.
