The first glycosylated isoferulic acid, isoferulic acid 3-O-β-glucopyranoside, together with the new phenolics, tamarixetin 3,3′-di-sodium sulphate and dehydrodigallic acid dimetyl ester have been characterized from a flower extract of Tamarix aphylla. The structures were established on the basis of spectral data. The extract exhibited a distinct radical scavenging effect and to improve the viability of human keratinocytes (HaCaT cells). Also, the known isoferulic acid and ferulic acid which have been determined to be the major components of the investigated extract by HPLC/ESI mass spectrometric screening have been separated, characterized and evaluated as active antioxidants and as cell activity stimulating agents as well.
从 Tamarix aphylla 的花提取物中鉴定出了第一种糖基化的异阿魏酸(异阿魏酸 3-O-β-吡喃葡萄糖苷),以及新的酚类物质--柽柳黄素 3,3′-二硫酸钠和脱氢双胍酸二甲酯。根据光谱数据确定了它们的结构。该提取物具有明显的自由基清除作用,并能提高人类角质细胞(HaCaT 细胞)的活力。此外,通过 HPLC/ESI 质谱筛选确定的已知异阿魏酸和阿魏酸是所研究提取物的主要成分,它们作为活性抗氧化剂和细胞活性刺激剂已被分离、表征和评估。
