dc.description.abstract | ABSTRACT The present investigation entitled “Development and evaluation of basil based herbal tea” was carried out in the laboratory of the Department of Forest Products, College of Forestry, Dr YS Parmar University of Horticulture and Forestry, Nauni, Solan (HP) during 2020-21. Eight different types of herbal teas were developed using different medicinal plants and examined in comparison with two different market herbal teas for their physicochemical properties. The developed herbal teas were evaluated for their total phenolic content, total flavonoid content, total polyphenolic content and antioxidant properties through different assays. All the raw material used for the development of herbal teas was also analyzed for their physicochemical properties. Out of the 8 different developed herbal teas, the treatment T2 scored best with overall acceptability of 8.17 in the sensory evaluation as compared to market herbal tea, with a score of 6.82. The treatment T2 showed highest total phenolic content, total flavonoid content and total polyphenolic content as well. Five different antioxidant evaluation assays viz. DPPH radical scavenging assay, nitric oxide scavenging assay, reducing power assay, hydrogen radical scavenging assay and total antioxidant assay were used to evaluate the antioxidant activity of developed herbal tea. The herbal teas tested in this study showed significant antioxidant activities. The herbal tea T2 outperformed all the developed herbal teas and market herbal teas in the antioxidant assays. The correlation values between the antioxidant assays and total phenolic/flavonoid content showed that the teas which had the most augmented polyphenolic content commensurated with the antioxidant capacity. The total phenolic content of treatment T2 was 201.13 ± 8.02 mg GAE/g which was very high in comparison to the market herbal tea i.e. 108.46 ± 5.13 mg GAE/g. The total flavonoid content of treatment T2 was 138.97 ± 3.87 mg RE/g while that of market tea was 69.23 ± 3.69 mg RE/g. From our results, it can be concluded that the developed basil based herbal teas showed high total phenolic content, total flavonoid content, total polyphenolic content and antioxidant activities, as compared to herbal teas procured from local market | en_US |
