其中二苯甲酮2，2‘，5，6’-四羟基二苯甲酮(1)和5-羟基-3-甲氧基二苯甲酮(2)分别为新鉴定的轮叶金丝桃叶和茎皮中的天然产物，以及已知化合物Friedelin(3)，白桦酸(4)，香豆素A(5)，1，3，6-三羟基二苯甲酮(6)，异阿香酚(7)，谷甾醇3-O-β-D-葡萄糖苷(8)，1-羟基-6-甲氧基吡喃酮(9)，6，7-二羟基-1，3-二甲氧基蒽酮(10)，3-羟基-5-甲氧基黄原酮(11)，1，7-二羟基-3，6-二甲氧基口山酮(12)和胡萝卜素A(13)。它们的结构通过波谱方法确定，并与已发表的数据进行了比较。
A benzophenone, 2,2’,5,6’-tetrahydroxybenzophenone (1), and one xanthone, 5-hydroxy-3methoxyxanthone (2), were newly described as natural products from the leaves and the stem barks of Hypericum lanceolatum, along with the known compounds friedelin (3), betulinic acid (4), allanxanthone A (5), 1,3,6-trihydroxyxanthone (6), isogarcinol (7), sitosterol 3-O-β-D-glucopyranoside (8), 1-hydroxy-6methoxyxanthone (9), 6,7-dihydroxy-1,3-dimethoxyxanthone (10), 3-hydroxy-5-methoxyxanthone (11), 1,7dihydroxy-3,6-dimethoxyxanthone (12) and calophyllumin A (13). Their structures were elucidated by spectroscopic means and comparison with published data.
