可食用的蓝莓品种因其潜在的健康益处而被广泛认可。杜鹃花科果实包括北美高丛蓝莓（Vaccinium corymbosum L.）以及五种来自新大陆热带的不太常见的可食用蓝莓亲戚，Anthopterus wardii Ball，Cavendishia grandifolia Hoerld，Macleania coccoloboides A. C. Sm.，紫子树& Endl.，和Sphyrospermum cordifolium Benth的抗氧化性能和酚类化合物进行了研究。新热带浆果C. grandifolia和A.结果表明，瓦氏葡萄对DPPH·和ABTS·+的清除能力和铁离子螯合能力均显著高于伞房葡萄。总酚含量和HPLC-PDA组成指纹分析也进行了。总酚含量、DPPH·和ABTS·+清除率与铁螯合活性之间呈显著正相关。采用HPLC-PDA法鉴定了枸杞子中的酚类成分为绿原酸、对香豆酸、金丝桃苷、槲皮素-3-O-葡萄糖苷、异Orientin、异牡荆素、Orientin和牡荆素。主成分分析减少了抗氧化剂和总酚数据的两个组件，占95%的总变异之间的6个水果的尺寸。每种水果都形成了自己的簇，因此每种水果的抗氧化剂特性都是不同的。
Edible blueberry species are well recognized for their potential health benefits. Ericaceae fruits including the North American highbush blueberry (Vaccinium corymbosum L.) and five less common edible blueberry relatives from the New World tropics, Anthopterus wardii Ball, Cavendishia grandifolia Hoerld, Macleania coccoloboides A. C. Sm., Sphyrospermum buxifolium Poepp. & Endl., and Sphyrospermum cordifolium Benth, were investigated for their antioxidant properties and phenolic profiles. The Neotropical berries C. grandifolia and A. wardii exhibited significantly higher DPPH• and ABTS•+ scavenging and iron chelation activities than V. corymbosum. Total phenolic content and HPLC-PDA compositional fingerprint analyses were also carried out. Significant correlations were observed among total phenolic contents, DPPH• and ABTS•+ scavenging, and iron chelation activities. Using HPLC-PDA, the phenolic constituents in the berries were identified as chlorogenic acid, p-coumaric acid, hyperoside, quercetin-3-O-glucoside, isoorientin, isovitexin, orientin and vitexin. Principal components analysis reduced the dimensions of antioxidant and total phenolic data to two components, which accounted for 95% of total variation among the six fruits. Each fruit species formed its own cluster, and therefore the antioxidant profile of each species was shown to be distinct.
