New organic bases from amazonian Banisteriopsis caapi

Phytochemistry, 1975
Abstract Three new bases were isolated from Banisteriopsis caapi ; they are harmine N -oxide, harmic acid methyl ester (methyl 7-methoxy-β-carboline 1-carboxylate) and harmalinic acid (7-methoxy-3,4-dihydro-β-carboline 1-carboxylic acid).

New electrochemical method for the determination of β-carboline alkaloids, harmalol and harmine, in human urine samples and in Banisteriopsis caapi

Microchemical Journal, 2015
Abstract In this paper a new electrochemical method for determination of the β-carboline alkaloids, harmalol and harmine, using differential pulse voltammetry is presented. Experimental parameters such as pH, scan rate, pulse amplitude and pulse time were optimized to characterize their electrochemical behavior and to find best analytical conditions.
