Investigation of chemical constituents from the bark of Durio carinatus has led to the isolation of three lignans, boehmenan X (1), threo-carolignan X (2), and erythro-carolignan X (3), together with the three known lignans boehmenan, threo-carolignan E, and erythro-carolignan E. The bark of D. oxleyanus yielded two new lignan ethers, threo-carolignan Y (4) and erythro-carolignan Y (5), together with compounds 1, 3, and boehmenan. J-Based configurational analysis and NOE measurements were used to explore conformational issues for the lignan diastereomers, while CD measurements supported an 8'S configuration for the various lignans. The triterpenes 3β-O-cis-caffeoylbetulinic acid and 3β-O-trans-caffeoylbetulinic acid were also characterized from D. carinatus.
对棱果榴莲树皮的化学成分进行研究后,分离出了三种木脂素,即波希曼X(1)、苏式卡罗木脂素X(2)和赤式卡罗木脂素X(3),以及三种已知的木脂素波希曼、苏式卡罗木脂素E和赤式卡罗木脂素E。奥氏榴莲的树皮产生了两种新的木脂素醚,苏式卡罗木脂素Y(4)和赤式卡罗木脂素Y(5),以及化合物1、3和波希曼。基于J的构型分析和NOE测量用于探索木脂素非对映异构体的构象问题,而圆二色性测量支持各种木脂素的8'S构型。还从棱果榴莲中鉴定出了三萜3β-O-顺式咖啡酰桦木酸和3β-O-反式咖啡酰桦木酸。
