芦笋废弃物中黄酮化合物的结构鉴定及其稳定性研究

Identification and stability of flavonoids from asparagus waste

以芦笋废弃物为原料,提取其黄酮类化合物,并采用AB-8进行纯化。HPLC-MS/MS鉴定结果显示芦笋废弃物中黄酮主要有三种,分别为香叶木素、槲皮素-3-芸香糖葡萄糖苷(R2)和芦丁。揭示温度、pH、氧化剂、光照对R2和芦丁稳定性的影响,结果表明芦笋黄酮应避光,或在中性无氧化剂的溶液状态下保存或使用。

Flavonoids were extracted and purified by AB-8 from the asparagus waste. Three flavonoids,which were diosmetin ,quercetin-triglycoside（R2） and rutin ,were identified by HPLC-MS/MS. The effects of temperature,pH,oxidant and light on the stability of R2 and rutin were evaluated. The asparagus flavonoids should be stored in the neutral solution without antioxidant and light.
