Flavonoid contents as aglycones (for quercetin, kaempherol, isorhamnetin, luteolin and apigenin) were reported for 115 edible plants (91 species). Plant materials mostly originated in tropical zones were grown and harvested from AVRDC, Taiwan. Acid extraction and HPLC were used as analytical methods. Total flavonoid contents ranged from 0 to 254 mg/100g fresh weight. About 75% of samples were found to contain flavonoids > 0.5 mg/100g with the group mean 33 +/- 48 mg/100g. Data for only 30 samples (20 species) in this study are also available (measured as raw vegetables) in the USDA flavonoid database. This study can expand the flavonoid database and contribute to measurement of flavonoid intake, especially for populations consuming tropical and underutilized vegetables.
报告了115种可食用植物（91个物种）中作为苷元形式的类黄酮含量（针对槲皮素、山奈酚、异鼠李素、木犀草素和芹菜素）。大部分原产于热带地区的植物材料是在台湾农业生物技术中心种植和收获的。采用酸提取法和高效液相色谱法作为分析方法。总类黄酮含量范围为0至254毫克/100克鲜重。约75%的样品被发现含有类黄酮>0.5毫克/100克，组均值为33±48毫克/100克。本研究中仅30个样品（20个物种）的数据在USDA类黄酮数据库中也可获取（以生鲜蔬菜形式测量）。本研究可以扩充类黄酮数据库，并有助于类黄酮摄入量的测定，特别是对于食用热带和未充分利用蔬菜的人群。
