[Studies on chemical constituents in flower of Abelmoschus manihot].

To study the chemical constituents of Abelmoschus manihot. Chromatographic methods were used to isolate compounds from A. manihot, and spectroscopic methods were used to identify the structures. Thirteen compounds, myricetin (1), cannabiscitrin (2), myricetin-3-O-beta-D-glucopyranoside (3), glycerolmonopalmitate (4), 2, 4-dihydroxy benzoic acid (5), guanosine (6), adenosine (7), maleic acid (8), heptatriacontanoic acid (9), 1-triacontanol (10) , tetracosane (11), beta-sitosterol (12), beta-sitosterol-3-O-beta-D-glucoside (13) were obtained. 2-11 were obtained from the genus for the first time.
