摘　　要：本文采用电感耦合等离子体发射光谱法(ICP-OES)测定长果大头茶的叶片、嫩枝和树皮中的24种矿质元素的含量,并比较了24种矿质元素在长果大头茶不同部位的分布情况。结果显示,长果大头茶不同部位的矿质元素含量(μg/g)由高到低的顺序:嫩枝元素的含量(20442.16) >叶片元素的含量(17727.64) >树皮元素的含量(12668.05),其中Ca、K、Mg、Mn、P在长果大头茶的叶片、嫩枝及树皮中含量相对较高,Fe在树皮中的含量较高,K在树皮中含量较低。此外,长果大头茶的叶片中Zn/Cu = 0.2127,有利于人体胆固醇的代谢调节。The contents of 24 mineral elements in different part of Gordonia longicarpa were detected by ICP-OES and compared. Results showed that the contents of mineral elements in twigs (20442.16 μg/g) were higher than that in leaves (17727.64 μg/g) and barks (12668.05 μg/g). Different part of Gordonia longicarpa were rich in mineral elements and the contents of elements as Ca, K, Mg, Mn, P were high. Fe contents were rich and K contents were lacking in barks. Zn/Cu in leaves was 0.2127, which was helpful for metabolic regulation of cholesterol.
