摘　　要：实验采用国标法对四种泡桐花的营养成分进行了分析,并与其他常用植物性饲料蛋白源进行比较。结果表明：泡桐花中水分、蛋白质、纤维、脂肪、灰分分别占干重的8.69%～9.26%、10.8%～14.8%、3.5%～6.4%、11.3%～13.6%、5.4%～6.1%;矿物质元素中钙、磷含量为0.55%～0.72%和0.21%～0.42%,钙磷比为1.37%～2.35%;含18种氨基酸,总量为8.98%～10.36%,其中必需氨基酸含量为4.22%～4.81%,且必需氨基酸指数（EAAI）值较高,平均为1.11,具有开发成为蛋白质饲料的潜能。Nutrient components of four kinds of Paulownia flowers were analyzed used national standard method, and compared with other commonly used plant feed protein source. The results showed that.the Paulownia flowers water, protei n, fiber, fat, ash respectively 8.69% -9.26%, 10.8% - 14.8%, 3.5%-6.4%, 11.3% ~ 13.6%, 5.4% N6.1% of the total dry weight. Calcium,Phosphorus contents of mineral element in 0.55%-0.72% and 21%- 0.42%,the ratio of Calcium to Phosphorus was 1.37%-2.35%. The Paulownia flowers contain 18 kinds of amino acids,total 8.98%-10.36% ,essential amino acids content of which was 4.22%-4.81% and the essential amino acid index（EAAI） average value was 1.11. Paulownia flowers could be a kind of protein feed.
