Abstract:
Objective: To investigate the chemical constituents from Pogonatum inflexum. Methods: The constituents were separated by column chromatographic methods of silica gel, Sephadex LH-20 column chromatography and liquid phase preparation, and the structure of the compounds was identified by comparing the physicochemical properties of the compounds with the spectral data. Results: A total of 16 compounds were obtained from P. inflexum, which were identified as tricin (1), irisflorentin (2), 3,5,4'-trihydroxy-7,3'-dimethoxyflavone (3), 3,5,3'-trihydroxy-7,4'-dimethoxyflavanone (4), 5,2'-dihydroxy-6,7-methylenedioxy- flavanone (5), 5,2',3'-trihydroxy-6,7-methylenedioxyflavanone (6), apigenin (7), kaempferol (8), kaempferide (9), naringenin (10), quercetin (11), baicalein (12), luteolin (13), protocatechuic aldehyde (14), 4-hydroxy-3-methoxy-benzaldehyde (15), and 2-hydroxy-5-(2-hydroxy-4- methoxybenzyl)-4-methoxybenzaldehyde (16). Conclusion: All compounds are isolated from the genus Pogonatum for the first time, among them, dihydroflavones may be the characteristic components of this genus.
