Polyphenol compounds were extracted from Myrtus communis L. berries (Myrtaceae) by maceration in 70% ethanol and analysed by HPLC-DAD and electrospray mass spectrometry. The Myrtus berries were collected at maturity from seven localities on the island of Corsica (France) and the sampling was carried out during three years. The polyphenol composition of Corsican Myrtus berries was characterized by two phenolic acids, four flavanols, three flavonols and five flavonol glycosides. The major compounds were myricetin-3-O-arabinoside and myricetin-3-O-galactoside. Principal components analysis (PCA) is applied to study the chemical composition and variability of myrtle berries alcoholic extracts from the seven localities. Canonical analysis and PCA data distinguishes two groups of myrtle berries characterized by different concentrations of polyphenols according to soil and years of harvest. The variations in the polyphenol concentration were due to biotic and abiotic factors.
从桃金娘科（Myrtaceae）的桃金娘浆果（Myrtus communis L.）中通过在 70%乙醇中浸提提取多酚化合物，并通过 HPLC-DAD 和电喷雾质谱进行分析。在三年期间，从科西嘉岛（法国）的七个地方在成熟时采集了桃金娘浆果。科西嘉岛桃金娘浆果的多酚组成由两种酚酸、四种黄烷醇、三种黄酮醇和五种黄酮醇糖苷组成。主要化合物是杨梅素-3-O-阿拉伯糖苷和杨梅素-3-O-半乳糖苷。主成分分析（PCA）用于研究七个地点的桃金娘浆果醇提取物的化学成分和变异性。典范分析和 PCA 数据根据土壤和收获年份将桃金娘浆果分为两组，其特征在于多酚的浓度不同。多酚浓度的变化归因于生物和非生物因素。
