采用优化的RP-HPLC-UV检测法对25种可食浆果中槲皮素、杨梅素和山萘酚苷元的含量进行了分析，并采用二极管阵列和电喷雾质谱进行了鉴定。1997年在芬兰收集了16种栽培浆果和9种野生浆果。在所有浆果中发现槲皮素，含量最高的是沼泽越橘（158 mg/kg，鲜重）、越橘（74和146 mg/kg）、蔓越莓（83和121 mg/kg）、chokeberry（89 mg/kg）、甜罗旺（85 mg/kg）、罗旺莓（63 mg/kg）、沙棘浆果（62 mg/kg）和越橘（53和56 mg/kg）。在蔓越莓、黑醋栗、越橘、沼泽越橘、蓝莓和越橘中检测到14至142 mg/kg的杨梅素。仅在醋栗（16和19 mg/kg）和草莓（5和8 mg/kg）中检测到山奈酚。这些黄酮醇的总含量（100-263 mg/kg）在蔓越莓，沼泽越橘，越橘，黑加仑，和红莓高于那些在通常消费的水果或蔬菜，除了洋葱，羽衣甘蓝，和西兰花。
The amounts of quercetin, myricetin, and kaempferol aglycons in 25 edible berries were analyzed by an optimized RP-HPLC method with UV detection and identified with diode array and electrospray ionization mass spectrometry detection. Sixteen species of cultivated berries and nine species of wild berries were collected in Finland in 1997. Quercetin was found in all berries, the contents being highest in bog whortleberry (158 mg/kg, fresh weight), lingonberry (74 and 146 mg/kg), cranberry (83 and 121 mg/kg), chokeberry (89 mg/kg), sweet rowan (85 mg/kg), rowanberry (63 mg/kg), sea buckthorn berry (62 mg/kg), and crowberry (53 and 56 mg/kg). Amounts between 14 and 142 mg/kg of myricetin were detected in cranberry, black currant, crowberry, bog whortleberry, blueberries, and bilberry. Kaempferol was detected only in gooseberries (16 and 19 mg/kg) and strawberries (5 and 8 mg/kg). Total contents of these flavonols (100-263 mg/kg) in cranberry, bog whortleberry, lingonberry, black currant, and crowberry were higher than those in the commonly consumed fruits or vegetables, except for onion, kale, and broccoli.
