Talipariti elatum (Sw.) Malvaceae, also known as Blue Mahoe or Mountain Mahoe, commonly named as Majagua azul or Majagua, with red or crimson flowers, is a medicinal tree traditionally used against cough, asthma, catarrh, and expectorant. Its flowers contain a lot different chemical compounds, mainly flavonoids. From red petals of the flowers a flavonol glucoside was isolated and characterized by TLC, UV, IR, HPLC-MS/MS and NMR spectroscopy. Structure analyses of that chemical component revealed that It have the identical glucoside moiety attached to a flavonol skeleton like gossypitrin (gossypetin-7-O--glucoside) but in different position for which the structure of gossypetin 3’-Oglucoside was deduced from HSQC, HMBC, COSY and NOESY correlations.
