Chemical analysis of the powdered leaves and root of Mallotus oppositifolium revealed the presence of alkaloids, cardiac glycosides and phenolic compounds with a higher concentration residing in the leaves than in the root. Antioxidant and antiinflammatory activities of the crude extracts in hexane and methanol were evaluated by the beta-carotene linoleate model system and the carrageenan induced rat paw oedema animal model. Both systems identified significant biological activity in the methanolic crude extract of the leaf. Thin layer chromatographic (TLC) analysis of the crude extract in methanol identified four phenolic spots two of which were flavonoid in nature (UV(254nm, 356nm), FeCl3 and AlCl3 visualization).
对反叶野桐的叶粉和根进行化学分析发现,其中存在生物碱、强心苷和酚类化合物,叶中的浓度高于根。通过β-胡萝卜素亚油酸酯模型系统和角叉菜胶诱导的大鼠足肿胀动物模型,评估了己烷和甲醇中粗提物的抗氧化和抗炎活性。两个系统均在叶的甲醇粗提物中鉴定出显著的生物活性。对甲醇中的粗提物进行薄层色谱(TLC)分析,鉴定出四个酚类斑点,其中两个本质上是黄酮类(紫外光(254nm、356nm)、三氯化铁和三氯化铝显色)。
