摘要
本研究是对林东地衣植物化学研究的延续。采用不同的色谱方法分离得到8′- o -甲基原癸酸(1)、原癸酸(2)、绿藻酸(3)、次绿藻酸(4)、巴巴酸(5)、衍射酸(6)、4- o -去甲基巴巴酸(7)、天冬氨酸(8)等8个化合物。通过光谱分析以及与文献数据的比较，阐明了它们的化学结构。
Phenolic compounds from Usnea baileyi (Stirt.) Zahlbr growing in Lam Dong province
This study entails a continuation of the phytochemical study regarding the lichen Usnea baileyi collected in Lam Dong province. Eight compounds, 8'-O-methylprotocetraric acid (1), protocetraric acid (2), virensic acid (3), subvirensic acid (4), barbatic acid (5), diffractaic acid (6), 4-O-demethylbabartic acid (7), and atranorin (8), were isolated using various chromatographic methods. Their chemical structures were elucidated through spectroscopic analysis as well as through a comparison of their data with that in the literature.
