Antioxidant activity of an isomer of gossypitrin (gossypetin-3’-O-glucoside) isolated in the petals of Talipariti elatum Sw., and determination of total phenolic content of the total flower

Frantz François-Haugrin, Max Monan, Emmanuel Nossin, Juliette Smith‐Ravin et autres

Objective: Isolation and identification of the main flavonoid from petals of Talipariti elatum Sw. (Hibiscus elatus Sw), comparison of antioxidant properties, determination of total phenolic content of the flower. Method: The main flavonoid was precipitated using 1, 2 - dimethoxyethane, followed by …

Isolation and Characterization of Flavonols by HPLC-UV-ESI-MS/MS from Talipariti elatum S.w

José González Yaque, Armando Cuéllar Cuéllar, Lionel Massi, Max Monan et autres

The red petals of the flowers of Talipariti elatum, commonly named majagua is used as antitussive, expectorant and antasthmatic in phytotherapy, although the plants’ composition has not been determined in detail so far. Hence, in this study, we present a validated, sensitive, …

New Reported Flavonol Characterized by NMR from the Petals of Talipariti elatum S. w. in Cuba

José González Yaque, Armando Cuéllar Cuéllar, Marc Gaysinski, Max Monan et autres

From yellow petals of Blue Mahoe, besides the known flavonoids gossypetin and gossypitrin, a new one gossypetin derivative was isolated from ethanolic extracts after Soxhlet extraction. Hence, in this study, we present a validated, sensitive and reliable NMR method for the simultaneous …
