“…Tyrosol was then converted by a glycosyltransferase (specifically, T8GT) to produce salidroside ( Torrens-Spence et al, 2018 ). As a compound that was upregulated after fermentation, pyrocatechol was an important phenolic compound in jujube puree ( Dilek Tepe & Doyuk, 2020 ). The increase in pyrocatechol content may have been due to promotion of the degradation of phenylalanine by S. thermophilus ( Fig.…”

“…The antioxidant capabilities of extracts might be attributed to the presence of phenols, flavonoids, and various other chemical constituents. GC-MS and HPLC analysis detected antioxidant-containing compounds, including 2-(4-methyl-1H-1,2,3-triazol-1-yl)ethan-1-amine [43], 4H-pyran-4-one, 2,3-dihydro-3,5-dihydroxy-6-methyl [42], 3-deoxy-D-mannoic lactone [47], stigmasterol [55], chlorogenic acid [60], and The in vitro observation of the inhibitory effect of C. rotundus kombucha on alphaglucosidase activity was confirmed in vivo using a Drosophila model. As shown in Figure 5B, Drosophila fed a high-sugar diet supplemented with 100% kombucha demonstrated a 34.04% decrease in glucosidase activity compared to those fed a high-sugar diet alone (p < 0.001).…”

The results of this study, combined with previous research, strongly suggest that the antioxidant potential of C. rotundus kombucha is linked to its antioxidant capacity and the activation of antioxidant enzymes.…”

Cyperus rotundus L. exhibits promising potential for the development of functional foods due to its documented pharmacological and biological activities. This study investigated the antioxidant and anti-diabetic properties of C. rotundus kombucha. The results demonstrated potent antioxidant activity with an IC50 value of 76.7 ± 9.6 µL/mL for the DPPH assay and 314.2 ± 16.9 µL/mL for the ABTS assay. Additionally, the kombucha demonstrated alpha-glucosidase inhibitory with an IC50 value of 142.7 ± 5.2 µL/mL. This in vitro antioxidant potential was further validated in vivo using Drosophila. Drosophila fed a high-sugar diet and supplemented with pure kombucha revealed significant increases in DPPH and ABTS free radical scavenging activity. Drosophila on a high-sugar diet supplemented with varying kombucha concentrations manifested enhanced resistance to oxidative stresses induced by H2O2 and paraquat. Concurrently, there was a notable decline in lipid peroxidation levels. Additionally, significant upregulations in CAT, SOD1, and SOD2 activities were observed when the high-sugar diet was supplemented with kombucha. Furthermore, in vivo assessments using Drosophila demonstrated significant reductions in alpha-glucosidase activity when fed with kombucha (reduced by 34.04%, 13.79%, and 11.60% when treated with 100%, 40%, and 10% kombucha, respectively). A comprehensive GC-MS and HPLC analysis of C. rotundus kombucha detected the presence of antioxidative and anti-glucosidase compounds. In conclusion, C. rotundus kombucha exhibits considerable antioxidant and anti-diabetic properties, demonstrating its potential as a beneficial beverage for health promotion.

Garcinia gummi-gutta, also known as Garcinia cambogia, is a member of the Guttiferae family. Garcinia is a polygamous genus consisting 200 species of trees and shrubs. It is found in different zones of the planet including Asia's tropical regions. In India alone, around 30 species have been discovered. They are widely used as a flavoring agent to garnish fish curry in southern India, particularly in Kerala and Karnataka. The fruit rind of G. gummi-gutta has traditionally been used to treat gastrointestinal problems, diarrhea, and ulcers. South Indian people have been utilizing it traditionally as evidenced by its ethnobotanical properties. In vivo and in vitro effects of the crude fruit extract showed anti-inflammatory, anti-cancer, anthelmintic, anti-microbial, and antioxidant activities. G. gummi-gutta fruit rind is medicinally significant and is frequently used in ayurvedic and traditional medicine for many diseases. Various secondary metabolites such as organic acids-hydroxycitric acid (HCA), flavonoids, terpenes, polysaccharides and polyisoprenylated benzophenonesgarcinol, xanthochymol, guttiferone, benzophenone, xanthone, biflavonoids, alkaloids, tannins, phenols, and saponins isolated from the G. gummi-gutta have diverse pharmacological activities. This review provides a summary of G. gummi-gutta, including its biological activities, phytochemistry, and ethnobotanical applications.
