Liquid chromatography (LC) coupled with UV detection and electrospray ionization (ESI) tandem mass spectrometry (MS/MS) was used for the generation of chemical fingerprints and the identification of phenolic compounds in peumo fruits and aerial parts from southern Chile. Thirty three compounds (19 of these detected in C. alba and 23 in C. monogyna) were identified, mainly flavonoid glycosides, phenolic acids, anthocyanins and flavonoid aglycons. Total phenolic content and total flavonoid content was measured for both species, and were higher in the extracts from C. monogyna fruits and aerial parts than extracts from C. alba. The fruits of Cryptocarya alba (Chilean peumo) presented high antioxidant capacity (9.12 ± 0.01 mg/mL in the DPPH assay), but was three times lower to that of Crataegus monogyna (German peumo) (3.61 ± 0.01 mg/mL in the DPPH assay).
采用液相色谱（LC）与紫外检测和电喷雾电离（ESI）串联质谱（MS/MS）联用的方法，生成化学指纹图谱，并鉴定智利南部的 peumo 果实和地上部分中的酚类化合物。鉴定出 33 种化合物（19 种在 C. alba 中检测到，23 种在 C. monogyna 中检测到），主要为类黄酮糖苷、酚酸、花青素和类黄酮苷元。对两种物种的总酚含量和总黄酮含量进行了测定，结果表明 C. monogyna 果实和地上部分的提取物中的含量高于 C. alba。智利 peumo（Cryptocarya alba）果实具有较高的抗氧化能力（DPPH 测定法中为 9.12±0.01mg/mL），但比德国 peumo（Crataegus monogyna）低三倍（DPPH 测定法中为 3.61±0.01mg/mL）。
