金丝桃油在传统医药中外用于治疗局部创伤和内服治疗中度抑郁症。将贯叶金丝桃(Hypericum perforaturm L. )的新鲜花浸在橄榄油,黄豆油、葵花籽油或其它脂肪油中,得到红色脂肪油。笔者比较了商品的和试验室制备的金丝桃油中金丝桃素的浓度。金丝桃油用氯仿稀释,采用光度计测定仪(590nm)测定金丝桃素的浓度。商品油在0.58～2.63mg/100ml之间,发现这种大的变化取决于 Hypericum oil is used both in traditional medicine and in the treatment of local trauma and internal treatment for moderate depression. Fresh flowers of Hypericum perforaturm L. are soaked in olive oil, soybean oil, sunflower oil or other fatty oils to obtain red fatty oils. The authors compared the concentration of hypericin in Hypericum oil prepared from commercial and laboratory facilities. Hypericum oil was diluted with chloroform and the concentration of hypericin was measured using a luminometer (590 nm). The commercial oil is between 0.58 and 2.63 mg/100 ml. It is found that this large change depends on
