BACKGROUND
The extracts from the leaves of Otostegia integrifolia have been reported to show phytochemical analysis, total flavonoid content, antioxidant and antibacterial activities.
RESULTS
Our results revealed that the total flavonoid content of methanol and ethyl acetate extracts is 416.5 + 0.288 and 248.9 + 0.872 mgAAE/100 g respectively. The two extracts also showed good antioxidant activity as well as weak to moderate antibacterial activity against some bacteria.
CONCLUSIONS
The leaf extracts from O. integrifolia showed good total flavonoid content, DPPH radical scavenging activity and antibacterial activity. In addition to this, the extracts also showed the presence of some important compounds by phytochemical analysis.
背景
据报道，全缘耳草叶提取物已进行了植物化学分析、总黄酮含量测定、抗氧化及抗菌活性研究。
结果
我们的结果显示，甲醇提取物和乙酸乙酯提取物的总黄酮含量分别为416.5±0.288和248.9±0.872 mgAAE/100 g。这两种提取物还表现出良好的抗氧化活性以及对某些细菌的弱至中等抗菌活性。
结论
全缘耳草叶提取物显示出良好的总黄酮含量、DPPH自由基清除活性和抗菌活性。除此之外，通过植物化学分析，提取物还显示出一些重要化合物的存在。
