Lassi, a popular curd based traditional fermented milk beverage of India. Lassi was prepared from standardized cow milk curd using 1% commercial yoghurt culture containing Streptococcus thermophilus and Lactobacillus bulgaricus. Maximum concentration of herbal extract added during processing of herbal lassi was optimized with Turmeric (Curcuma longa) @ 1% (v/v) in lassi on the basis of sensory evaluation. Total phenolic content (TPC) of turmeric extract based herbal lassi was also evaluated. TPC of the turmeric based herbal lassi was measured as Gallic Acid Equivalent (GAE) using a double beam UV- visible spectrophotometer at 765 nm. The TPC of the turmeric extract fortified lassi was found to be 0.226±0.001mg of GAE/g and differed significantly (P less than 0.05) with the control lassi (without any herbal extract) which showed a TPC of 0.124±.001 mg of GAE/g. Turmeric lassi was found having high phenolic content with good sensory property and found acceptable up to 9 days when stored at 7±2 0C in a glass bottle.

Abstract Background Rumex abyssinicus (RA) is one of indigenous plants to Ethiopia having traditional values during butter refinement in rural areas. This paper presents a comparative study of the antioxidant and antibacterial activities of RA sample extract to that of Zingiber officinale (ZO) and Curcuma longa (CL). Methods Phytochemical screening tests were, first, done using different confirmatory tests prior to quantitative determinations. Quantitative determinations were then conducted—the total phenolic content by the Prussian blue method, total flavonoid content by the aluminum colorimetric assay, and antioxidant activity by the reducing power assay and the cyclic voltammetry technique. Results All of the samples showed positive tests, with different intensities, for the presence of phenolics, flavonoids, glycosides and tannins, but not for alkaloids. The total phenolic content, the total flavonoid content and the antioxidant activities of RA (in mg/100 g dry weight) were found to be 319.208 ± 15.997, 113.252 ± 1.702 and 45.632 ± 2.026, respectively. On the other hand, both oxidation and reduction peaks were observed in the cyclic voltammetry analysis of the herbs, showing a quasi-reversible redox process of their phenolic compounds. The determination of the inhibition zones (in mm) of ethanol extract of RA was found to be 20.33 ± 0.58, 21.67 ± 0.58, 19.17 ± 0.29, 18.17 ± 0.29, and 21.67 ± 0.58 against Staphylococcus aureus, MRSA, Streptococcus pneumonia, Escherichia coli, and Shigella flexneri bacteria strains, respectively. Conclusion The substantial antioxidant and antibacterial activities of RA compared to ZO and CL indicate that the traditional use of the herb to refine butter and keep it safe longer without rancidity formation and other traditional medicinal practices can be attributed to both its antioxidant and antibacterial activities.

This study was aimed to identify the chemical characteristics of white and yellow turmeric powder, and to investigate the influence of both types with three different solvents on yield, total phenolic content, curcuminoid, antioxidant, and antibacterial activity of curcumin crude extract. The curcumin extraction was performed by maceration using N-hexane, ethyl acetate, and ethanol solvents. The results showed that the proximate analysis excluding carbohydrate content of white turmeric powder were lower compared to the yellow type. Curcumin crude extract of white turmeric powder had lower yield, total phenolic content, curcuminoid, antioxidant, and antibacterial activity compared to yellow turmeric extract. Moreover, turmeric extracted with ethyl acetate had higher total phenolic, curcuminoid, antioxidant, and antibacterial activity compared to turmeric extracted using N-hexane and ethanol. Based on the highest total phenolic (193.26 mg GAE/kg) and curcuminoid content (8.13 mg/L), the best treatment was yellow turmeric extract using ethyl acetate solvent. This treatment had the lowest IC50 (63.38 μg/ mL), and the highest clear zone size of S. aureus (6.59 mm) and E. coli (6.29 mm) at concentration of 2000 ppm.

Aims: Objective of this study was to determine the effect of addition gembili (Dioscorea esculenta) flour on the fermented milk was then evaluate the characteristics of fermented milk by analysis of pH, titratable acidity, viscosity, total phenolic content, crude fiber, sugar total, and total lactic acid bacteria. Study Design: This study employs a completely randomized design with five treatments adding gembili flour and three replications. Place and Duration of Study: Animal Product Technology Laboratory, Animal Product Technology Department, Faculty of Animal Science, Universitas Brawijaya, between April-October 2020. Methodology: Fermented milk is prepared by pasteurizing of skim milk and gembili flour. The concentration of gembili flour added were (0 (P1); 0.5% (P2); 1% (P3); 1.5% (P4); 2% (P5). Furthermore, the characteristics of fermented milk is carried out including pH, titratable acidity, viscosity, total phenolic content, crude fiber, sugar total, and total lactic acid bacteria of fermented milk using combination of three bacteria namely, Lactobacillus plantarum, Lactobacillus acidophillus, and Streptococcus thermophilus as a starter culture. Results: The results in this study revealed that the pH value ranged from 3.5-4.3; titratable acidity 1.98-2.35%; viscosity 849-1856 cps; sugar total 2.8-4.11 g/100g; total lactic acid bacteria 3.05 x 107 - 3.21 x 108 cfu/ml respectively. Total phenolic content and crude fiber in P1 was not detected, but in P2-P5 had total phenolic and crude fiber ranging from 108,58 – 670,75 mg/kg and 0.57-2.16 g/100 g, respectively. Conclusion: The addition of gembili flour to the fermented milk contributes to the quality of fermented milk product which include pH, titratable acidity, viscosity, total phenolic content, crude fiber, sugar total, and total lactic acid bacteria.

The current investigation is intended to evaluate the content of phytochemical constituents and antioxidant potential of hydroalcoholic extracts of stem and root of Grewia serrulata DC (HAESGS & HAERGS) and leaf and bark of Grewia Nervosa (Lour.) panigrahi (HAELGN & HAEBGN). Initially, all the extracts at different concentrations were estimated for their total phenolic content and total flavonoid content. The study was further extended for their antioxidant potential evaluation using various in vitro methods such as 1, 1-diphenyl-2-picrylhydrazyl (DPPH) radical, hydroxyl radical and superoxide radical scavenging assays. The total phenolic content (mg gallic acid equivalent per gram of extract) was high in HAELGN (170.82±0.19) and HAERGS (123.00±0.48) than HAESGS (111.2±0.26) and HAEBGN (119.60±0.23). The total flavonoid content (mg quercetin equivalent per gram) is greater in HAERGS (71.24±0.50) and HAESGS (65.68±0.27) than HAELGN (55.82±0.35) and HAEBGN (62.38±0.45). The IC50 values (µg/ml) of different plant extracts inferred that DPPH radical scavenging activity is greater in HAELGN (42.91±0.88) and HAEBGN (53.87±0.35) than HAESGS (126.73±1.20) and HAERGS (88.87±1.25). However, hydroxyl and superoxide radical scavenging activity is more in HAERGS (135.41±1.19 & 88.00±1.42) and HAELGN (172.28±1.91 & 108.163±1.09) than HAESGS (237.3±1.65 & 110.074±0.87) and HAEBGN (204.7±1.04 & 125.54±1.07). The results of present comprehensive analysis demonstrated that both the plants Grewia serrulata DC and Grewia Nervosa (Lour.) panigrahi possess high phenolic, flavonoid contents and potential antioxidant activity, and could be used as a valid source of natural antioxidants and might be utilized for pharmacological screening of various therapeutic activities.
