Three E-cinnamic acid glycosides, tryptophan, and cyanidin-3-O-beta-D-glucopyranoside were isolated from ripe fruits of the Chilean strawberry Fragaria chiloensis ssp. chiloensis. 1-O-E-Cinnamoyl-beta-D-xylopyranoside, 1-O-E-cinnamoyl-beta-D-rhamnopyranoside, and 1-O-E-cinnamoyl-alpha-xylofuranosyl-(1-->6)-beta-D-glucopyranose are reported for the first time. The cinnamic acid glycosides and aromatic compound patterns in F. chiloensis fruits were determined by high-performance liquid chromatography (HPLC). HPLC analyses of extracts showed that cyanidin-3-O-beta-D-glucopyranoside and free ellagic acid are present in achenes while the E-cinnamoyl derivatives and tryptophan were identified only in the thalamus. The free radical scavenging effect of the fruit extract can be associated with the anthocyanin content.
从智利草莓智利草莓亚种智利草莓的成熟果实中分离出三种肉桂酸糖苷、色氨酸和矢车菊素-3-O-β-D-吡喃葡萄糖苷。首次报道了1-O-E-肉桂酰基-β-D-吡喃木糖苷、1-O-E-肉桂酰基-β-D-吡喃鼠李糖苷和1-O-E-肉桂酰基-α-D-呋喃木糖基-(1→6)-β-D-吡喃葡萄糖。通过高效液相色谱法（HPLC）测定了智利草莓果实中的肉桂酸糖苷和芳香化合物模式。提取物的HPLC分析表明，瘦果中存在矢车菊素-3-O-β-D-吡喃葡萄糖苷和游离鞣花酸，而E-肉桂酰衍生物和色氨酸仅在花托中被鉴定出来。果实提取物的自由基清除作用可能与花青素含量有关。
