OBJECTIVE
To study the chemical constituents of Usnea longissima.
METHOD
The compounds were isolated and purified by the methods of solvent extraction and chromatographic technique, and their structures were identified on the basis of the analyses of spectral data.
RESULT
Two compounds were obtained and identified as 3, 6-diacetyl-2, 7, 9-trihydroxy-8, 9b-dimethyl-1 [9bH]-dibenzofuranone(1) and 1, 3, 8-trihydroxy4, 6-dimethyl-9, l0-anthracenedione(2), respectively.
CONCLUSION
Compounds 1 and 2 were new compounds and were named as longiusnine and longissimausnone, respectively.
目的
研究长松萝的化学成分。
方法
采用溶剂萃取和色谱技术方法分离纯化化合物，并根据光谱数据分析鉴定其结构。
结果
得到两个化合物，分别鉴定为3,6 - 二乙酰基 - 2,7,9 - 三羟基 - 8,9b - 二甲基 - 1 [9bH] - 二苯并呋喃酮（1）和1,3,8 - 三羟基 - 4,6 - 二甲基 - 9,10 - 蒽二酮（2）。
结论
化合物1和2为新化合物，分别命名为长松萝宁和长松萝蒽醌。
