Two new lignans, zanthoxyloside C (1) and zanthoxyloside D (2), together with nine known compounds comprising lignans (3-5), flavonoids (6-8), and phenolics (9-11), were isolated from the methanol extract of the stems of Zanthoxylum piperitum. All isolates were evaluated for their antioxidant and anti-osteoporotic activities using oxygen radical absorbance capacity (ORAC), cupric reducing antioxidant
从甲醇提取物中分离出了两种新的木脂素,花椒苷C(1)和花椒苷D(2),以及九种已知的包含木脂素(3-5),类黄酮(6-8)和酚类(9-11)的化合物。花椒的茎。使用氧自由基吸收能力(ORAC),铜还原抗氧化剂能力(CUPRAC)和抗酒石酸酸性磷酸酶(TRAP)分析评估所有分离株的抗氧化和抗骨质疏松活性。化合物7-10显示出过氧自由基清除能力,化合物4、6-7和9显示出还原能力。此外,化合物3、6-9和11显着抑制了TRAP活性。这些结果表明,Z.piperitum的茎可能是天然抗氧化剂和抗骨质疏松症的极好来源。
