Alkaloids from Mongolian species of Peganum multisectum (Maxim) Bobrov

摘要

Alkaloids of the aerial parts of P. multisectum (Maxim) Bobrov (Zygophyllaceae) growing in Mongolia have been studied by capillary Gas Chromatography-Mass Spectrometry (GC-MS) and Column Chromatography (CC). Four compounds comprising of 2-methylquinoline ( 1 ), 9-amino-2, 3,5,6,7,8-hexahydro-1H-cyclopenta [b] quinoline ( 2 ), vasicinone ( 3 ) and harmine ( 4 ) have been determined by GC-MS, while harmine ( 4 ), peganine ( 5 ), deoxypeganine ( 6 ), deoxyvasicinone ( 7 ) and harmane ( 8 ) were isolated as pure compounds by the CC. The structures of the five alkaloids 4 , 5 , 6 , 7 and 8 were elucidated by the MS and 1 H and 13 C NMR analysis. The alkaloids 1 , 2 and 8 were identified for the first time from this species.
