Phytochemical screening and HPLC- UV method quantification of Flavonoids in Coffee Arabica green seeds

Abstract

The green coffee bean is the most commonly used beverages in India and it is one of the most commercialised food products. They have a rich source of biologically active compounds that are important for human health. The coffee tree or a shrub belongs to the family Rubiaceae. Commercially available, two species of green coffee bean are Coffea Arabica and Coffea canephora. Cancer is the most important cause of death. Apart from cancer, quercetin can also prevent Osteoporosis. The phytochemicals present in the green coffee bean can be used as an alternate therapy for cancer due to its antimitotic activity and free radical scavenging activity. Total antioxidant shows IC₅₀ value 45.81. Kaempferol is a potent antioxidant that can defence against free radicals and cure chronic diseases. Flavonoids are phenolic substances that act as an antioxidant, anti-inflammatory, anti-allergenic, antiviral and also have vasodilating actions. Green coffee bean shows a high concentration of Flavonoids in hydroethanolic extraction. The aim of this study is used to analyse the presence of Flavonoids in green coffee bean by using High-performance Liquid Chromatography (HPLC). Flavonoids are potent antioxidant that can bind to a protein. Flavonoids show a wide range of biological and pharmacological activities like anti-allergic, anti-inflammatory, anti-cancer and anti-microbial activity.
