Abstract
In the present work we investigated the banana peels (<i>Musa cavendishii</i>) of organic silk variety from Pachacamac (Lurín, Lima) for being waste contaminants without use that avoid the damage to the environment. The qualitative presence of polyphenols and flavonoids was determined by phytochemical marching developed in ethanol extract of banana peels. Using thin layer chromatography on an analytical and preparative scale and rapid column chromatography, it was possible to separate nine soluble fractions in methanol and five soluble fractions in double distilled water as well as their respective Rf values; and by UV-visible spectrophotometry were elucidated nine structures of methanol soluble flavones (5,7-dihydroxy-4'-methoxyflavone, 4',5,6,7-tetrahydroxyflavone, 5,7-dihydroxy-6-methoxyflavone, 4',5,7,8-tetrahydroxyflavone; 5,7,8-trihydroxyflavone, 4'5,7-trihydroxyflavone; 5,6-dihydroxy-7-methoxyflavone, 5,6,7-trihydroxy-4'-methoxyflavone and 5,7-dihydroxy-4',6-dimethoxyflavone) and two flavones that were in double distilled water soluble (5,6,7-trihydroxyflavone, 5,6,7-trihydroxy-4'-methoxyflavone); in order to contributing to the study of the components of the organic banana peels and also to the environmental health.
Highlights
IntroductionIn Peru it is produced very thanks to geographical and climatic conditions, both for export and for the national market, in addition to the organic production of silk banana in agricultural areas of Lima, which attracts commercial interest
The banana is a widely spread fruit for its pleasant taste and low cost
In some cases and when it comes to organic production, can it be used as an integral element of the vegetable fertilizer, but on a very small scale; the peel is an important part that is not used in this fruit and for both the industry and consumers, it becomes a waste that should be processed [5]
Summary
In Peru it is produced very thanks to geographical and climatic conditions, both for export and for the national market, in addition to the organic production of silk banana in agricultural areas of Lima, which attracts commercial interest. While it is true that it can’t discuss the nutritional qualities of bananas [1,2,3]; there is a part of the fruit known as peel that is not harvested and constitutes a waste without industrial utility, in addition to producing and increasing pollution [4]. In some cases and when it comes to organic production, can it be used as an integral element of the vegetable fertilizer, but on a very small scale; the peel is an important part that is not used in this fruit and for both the industry and consumers, it becomes a waste that should be processed [5].
