Medicinal and Therapeutic Potentialities of Black and Green Teas (Camellia sinensis L.) Grown and Processed In-situ at PARC-NTHRI
Keywords:
Black Tea, Green Tea, Phytochemical, Proximate CompositionAbstract
The present study was initiated to investigate whether there is a significant difference in quality between black and green teas. A total of two samples (Black tea and Green tea var: Qi-men) were selected. Tea leaves were first selected, then processed into Black and Green teas
through various steps. Standard methods were carried out to analyze proximate composition of moisture content, ash content. Tea samples were evaluated and analyzed for chemical parameters i.e. polyphenols, Amino acids, steroids, terpenoids and crude fiber. This exercise was carried out for a period of 2 months. Extracts of different solvents were used i.e. Chloroform, Aqueous, n-hexane and ethanol. The results indicate that Flavonoids are present in all extracts. Saponins are found in all extracts except ethanol. Phenol, terpenoids, steroids and tannins are found in both aqueous and ethanolic extracts. Steriods, terpinoids and phenol are absent in n-hexane extract. Green tea has higher polyphenol content as compared to black tea in aqueous, chloroform and ethanol but in n-hexane extract black tea has higher polyphenols. Green tea has less amino acid content as compared to black tea.
