一类新的天然产物——逆转录二氢查尔酮——的前四种成员已从龙血树的叶子中分离出来。龙血素 1-4 [4''-羟基-2,4-二甲氧基二氢查耳酮的结构； 4''-羟基-2,4,6-三甲氧基二氢查耳酮； 4,4''-二羟基-2-甲氧基二氢查耳酮； 4,6,4''-三羟基-2-甲氧基二氢查尔酮]通过解释其光谱数据，特别是使用选择性INEPT核磁共振技术来阐明。
The first four members of a new class of natural products, the retrodihydrochalcones, have been isolated from the leaves of Dracaena loureiri. The structures of the loureirins 1-4 [4''-hydroxy-2,4-dimethoxydihydrochalcone; 4''-hydroxy-2,4,6-trimethoxydihydrochalcone; 4,4''-dihydroxy-2-methoxydihydrochalcone; 4,6,4''-trihydroxy-2-methoxydihydrochalcone] were elucidated through interpretation of their spectroscopic data, with particular use being made of the selective INEPT nmr technique.
