Abstract

The phenolic content of lavandin waste obtained after the distillation of essential oils for the perfume industry was investigated to find an alternative use for this material. The antioxidant activity of different fractions as well as their total phenolic content were evaluated by different methods. Twenty-three phenolic compounds were identified by liquid chromatography coupled to ionspray mass spectrometry (LC/MS/MS), including phenolic acids, hydroxycinnamoylquinic acid derivatives, glucosides of hydroxycinnamic acids, and flavonoids, none of which have previously been reported in lavandin waste. Some structure-activity relationships were proposed by relating the type of scavenging activity of different fractions with the identified phenolic compounds. Contents of representative phenolic acids of Lamiaceae (chlorogenic and rosmarinic) were evaluated by high performance liquid chromatography-diode array detection (HPLC-DAD) and compared with those of other plant species.

摘要

对香水行业精油蒸馏后得到的熏衣草废弃物中的酚类成分进行了研究，以寻找该材料的其他用途。采用不同方法评估了不同馏分的抗氧化活性及其总酚含量。通过液相色谱-离子喷雾质谱联用（LC/MS/MS）鉴定了23种酚类化合物，包括酚酸、羟基肉桂酰奎宁酸衍生物、羟基肉桂酸糖苷和黄酮类化合物，这些化合物此前均未在熏衣草废弃物中报道过。通过将不同馏分的清除活性类型与鉴定出的酚类化合物相关联，提出了一些构效关系。通过高效液相色谱-二极管阵列检测（HPLC-DAD）对唇形科代表性酚酸（绿原酸和迷迭香酸）的含量进行了评估，并与其他植物物种的含量进行了比较。
