This study reports the isolation of a new phenylethanoid glucoside (1) from the leaves of Jacaranda mimosifolia along with jacaranone (2), followed by the comparative estimation of total antioxidant compounds, total polyphenols and total flavonoids from different solvent extracts of the leaves and flowers. The total antioxidant activity was evaluated by both DPPH and ABTS free-radical scavenging assay methods from different solvent extracts of J. mimosifolia leaves and flowers. The antioxidant activities of the purified compounds (1 and 2) were detected by DPPH-TLC method.
本研究从蓝花楹的叶子中分离得到一种新的苯乙醇苷（1），并分离得到 Jacaranone（2），随后对不同溶剂提取物的总抗氧化化合物、总多酚和总类黄酮进行了比较评估。通过 DPPH 和 ABTS 自由基清除 assay 方法，从不同溶剂提取物的蓝花楹叶和花中评估了总抗氧化活性。通过 DPPH-TLC 方法检测了纯化化合物（1 和 2）的抗氧化活性。
