Industrially the avocado pulp is exploited principally as oil and paste, generating a huge quantity of peel and seed as by-products. Avocado peel is a promising inexpensive candidate for recovery phenolic compounds. The aim of this work was to identify the bioactive compounds present in an extract of avocado peel obtained by a green extraction technique. Accelerated solvent extraction was performed using water and ethanol as extraction solvents. Liquid chromatography coupled to ultra-high-definition accurate-mass spectrometry was used in order to identify the bioactive compounds. A total of sixty-one compounds belonging to eleven families were identified. Procyanidins, flavonols, hydroxybenzoic and hydroxycinnamic acids were the most common compounds. A sum of thirty-five compounds has been identified here for the first time in avocado peel. These results confirm the potential of avocado peel as a source of bioactive ingredients for its use in the food, cosmetic or pharmaceutical sector.
工业上，鳄梨果肉主要被开发为油和糊状物，产生了大量的果皮和种子等副产品。鳄梨果皮是一种很有前途的廉价回收酚类化合物的候选材料。本工作旨在从一种采用绿色提取技术获得的鳄梨果皮提取物中鉴定出其中的生物活性化合物。采用水和乙醇作为提取溶剂，通过加速溶剂萃取法进行提取。采用液相色谱-超高分辨率精确质量质谱联用技术对生物活性化合物进行鉴定。共鉴定出 61 种属于 11 个家族的化合物。原花青素、类黄酮、羟基苯甲酸和羟基肉桂酸是最常见的化合物。其中有 35 种化合物是首次在鳄梨果皮中被鉴定出来。这些结果证实了鳄梨果皮作为生物活性成分的潜在来源，可用于食品、化妆品或制药领域。
