Determination by GC-MS of the Hexane Extract Components fromMalvaviscus penduliflorusFlowers Growing in Cuba

Abstract

Brew from flowers of Malvaviscus penduliflorus Cav (family Malvaceae) are used as sedativein Cuba, where this species is popularly known as "pasiflora". Until present, only a phytochemical screening of the aqueous extracts from flowers and leaves of this plant has been carried out. In such work saponines, sugars, alkaloids and flavonoids were identified. However, no report on its non-polar extract had been published, in which other bioactive compounds could be present. Taking into account these facts, the aim of this work was to study the composition of the hexanic extract of the M. penduliflorus flowers by GC-MS. Dried flowers were extracted in a Soxhlet apparatus with hexane during eight hours. Samples were dissolved in chloroform and derivatized with MSTFA. The extraction yielded 2.2 % and the obtained extract was a yellow pale solid. This extract was mainly composed of hydrocarbons (C9-C32, including squalene); fatty acids (C9:0-C30:0); sterols and fatty alcohols (C26OH-C32OH). This study is a contribution to the chemical composition knowledge of these flowers and could support the pharmacological properties as well as the safety of their extracts. To our knowledge, this is the first report about the chemical study of the apolar extract from the flowers of this plant grown in Cuba.

GC‒MS analysis of fatty acids of Malvaviscus arboreus leaves

“…In the same context, among the characterized fatty acids herein from M. arboreus leaves, palmitic, stearic, myristic, behenic, margaric, arachidic, and linoleic acids were also previously reported from the related species, Malvaviscus penduliflorus DC. through GC-MS based analysis of the n-hexane extract of its flowers [22]. In line with our current findings, palmitic and stearic acids have also dominated the fatty acid content of M. penduliflorus flowers.…”

Hepatoprotective potential of Malvaviscus arboreus against carbon tetrachloride-induced liver injury in rats

“…arboreus , are both showy ornamentals and culinary herbs, especially for their aerial parts, which are commonly used for preparation of salads, herbal teas, and herbal dyes [ 7 ]. Moreover, they have been traditionally used for the management of multiple health disorders, including fever, diarrhea, wounds, sore throat, tonsillitis, bronchitis, gastritis, stomachache, dysentery, liver and gall bladder problems, hypertension, cystitis, and kidney diseases [ 7 , 9 – 12 ].…”
