dc.description.abstractThe present study entitled “Development and evaluation of sage (Salvia officinalis) based herbal tea” was conducted in the Laboratory of Department of Forest Products, Dr Yashwant Singh Parmar University of Horticulture and Forestry, Nauni, Solan (HP) during the year 2022-2023. The present study involved the development of nine different herbal tea formulations and evaluation of their physico-chemical characterstics comparing to four control samples viz. two market controls (T10 and T11) and Ocimum sanctum and Matricaria chamomilla based herbal tea (T12 and T13). The developed herbal teas were assessed for their total phenolic content, total flavonoid content and antioxidant activities using different assays. The physicochemical parameters of each herbal ingredient used in the development of herbal teas were also examined. The T3 showed highest total phenolic content and total flavonoid content. Four different antioxidants assays viz. DPPH radical scavenging assay, nitric oxide scavenging assay, reducing power assay and hydroxyl radical scavenging assay were used to evaluate the antioxidant activity of developed herbal tea. The developed herbal teas showed significant antioxidant activities. Among all the developed herbal teas T3 exhibited the highest antioxidant activity in all assays. The total phenolic content of T3 was 221.51 ± 2.24 mg GAE/g of crude extract which was high in comparison to the market herbal tea i.e. 151.96 ± 4.68 mg GAE/g of crude extract. The total flavonoid content of T3 was 172.62 ± 4.12 mg RE/g of crude extract while that of market tea was 109.52 ± 3.57 mg RE/g of crude extract. Among the nine different developed herbal teas, the T5 scored best with overall acceptability of 8.75 in the sensory evaluation as compared to the control samples. The optimal infusion time and sample amount was found to be 5 minutes and 0.3 grams which showed highest phenolic and flavonoid content along with highest antioxidant activity. The finding of our study showed that the developed sage (Salvia officinalis L.) based herbal teas showed higher total phenolic content, total flavonoid content and antioxidant activities as compared to herbal teas procured from the market.
