Análise de produtos do metabolismo secundário na biomassa da banana verde

Abstract

The green cooked banana, popularly known as green banana biomass, is a cream of not ripe banana. The fruit is still green and it has a physiological action, because it is rich in Flavonoid, which is a class of secondary metabolites, distributed in abundance in the plant kingdom, being formed by the combination of derivatives synthesized from phenylalanine and acetic acid. The Flavonoids have several pharmacological actions, such as antitumor activity, anti-inflammatory, antioxidant, antiviral, cardiovascular protective effect and others. As there are few studies in these areas, the objective of this research is to analyze the presence of active principles in green banana biomass, reporting the presence of secondary metabolite of the class of Flavonoids, identifying this principle, allowing the understanding of new therapeutic applications of this product to bring about improvement or help the treatments of disease. The integral green banana biomass used as simples packed I am a vacuum acquired in the Maringá trade. The old maceration method was used to extract the active principle, using the solvent hexane, ethyl acetate and methanol. The extracts were dried under the reduced pressure through rotavaporation. The dried extracts were analyzed by thim layer metography and Shinoda’s reaction, to evaluate the presence of Flavonoids in these samples finally CLMS (Liquid Cromatography coupled to mass spectrometry) analyzes was performed to identify the photochemical composition of the extracts. In the extracts obtained with ethyl acetate were observed the presence of this molecules of Ferulic acid, Rutin, Synapic acid and Kaemperol 3-O-rutinose (Nicotiflorin).
