Background: Medicinal plants are considered a rich source of ingredients, which can be used in drug development and synthesis. Tinospora cordifolia (Wild.) Hook.f. & Thomson, commonly known as guduchi, heart-leaved moonseed and giloya is a herbaceous vine of the family Menispermaceae, has several beneficial properties including antioxidant activity. Aim: The present study was carried out to analyze the antioxidant activity of leaf and stem extracts of Tinospora cordifolia by using DPPH (1,1-Diphenyl-2-picrylhydrazyl) and ABTS (2,2´-azino-bis (3-ethylbenzothiazoline-6-sulfonic acid)) free radical scavenging assays. Materials and Methods: Dried and powdered leaves and stem of T. cordifolia were extracted with methanol. Ascorbic acid was taken as standard. Total phenolic content was estimated by using Folin-ciocalteu's reagent while total flavonoid content by aluminium chloride reagent to find the correlation of polyphenols with antioxidant activity. ABTS assay of methanolic leaf and stem extracts showed the highest scavenging activity as compared to the DPPH assay. Results: Methanolic stem extract showed higher phenolic and flavonoid content along with antioxidant activity as compared to the methanolic leaf extract. Conclusion: The stem extract exhibited more antioxidant activity than the leaf extract with regards to the all parameters analyzed.

Melastoma malabathricum and Chromolaena odorata are classified under broad-leaved weeds that are widely spread in the open land area. Melastoma malabathricum is commonly known as ‘‘senduduk’’, and C. odorata is locally known as “Pokok Kapal Terbang”. Both weeds are categorized as potential weeds as they have high nutritive value and are rich in chemical compounds. This study aimed to determine their chemical constituents and possible potential for antioxidant activity as these weeds have been reported to possess antioxidant properties. Screening of the plants was performed using standard methods and revealed the existence of various secondary metabolites such as saponins, terpenoids, phenols, tannins, and flavonoids of both weed extracts. Antioxidant activity was validated by the DPPH radical scavenging assay of M. malabathricum and C. odorata crude ethanol extract. The IC50 values for the percentage radical scavenging effects for the extracts were determined. The IC50 value of M. malabatrichum extract was 81.116 μg/mL, C. odorata was 312.903 μg/mL, Vitamin C was 31.023 μg/mL and BHA was 71.521 μg/mL respectively. The study showed that the antioxidant activity of M. malabatrichum was more potent and better than C. odorata.

AbstractOxidative damage of cells and tissues is broadly implicated in human pathophysiology, including cardiometabolic diseases. Polyphenols, as important constituents of the human diet and potent in vitro free radical scavengers, have been extensively studied for their beneficial effects on cardiometabolic health. However, it has been demonstrated that the in vivo antioxidant activity of polyphenols is distinct from their in vitro free radical-scavenging capacity. Indeed, bioavailability of nutritional polyphenols is low and conditioned by complex mechanisms of absorption, distribution, metabolism and excretion. Nowadays, it is commonly accepted that the cellular antioxidant activity of polyphenols is mainly carried out via modification of transcription of genes involved in antioxidant defence. Importantly, polyphenols also contribute to cardiometabolic health by modulation of a plethora of cellular processes that are not directly associated with antioxidant enzymes, through nutri(epi)genomic mechanisms. Numerous human intervention studies have demonstrated beneficial effects of polyphenols on the key cardiometabolic risk factors. However, inconsistency of the results of some studies led to identification of the inter-individual variability in response to consumption of polyphenols. In perspective, a detailed investigation of the determinants of this inter-individual variability will potentially lead us towards personalised dietary recommendations. The phenomenon of inter-individual variability is also of relevance for supplementation with antioxidant (pro)vitamins.

The present study examined the effect of Lactobacillus plantarum ATCC14917 fermentation on the chemical composition and antioxidant activity of apple juice. Apple juice was fermented and examined of its antioxidant activity using chemical models and cellular antioxidant assay. Furthermore, the chemical composition of fermented apple juice was characterized by LC-MS/MS. Lactobacillus plantarum ATCC14917 fermentation showed an increase in DPPH and ABTS radical scavenging activity as well as cellular antioxidant activity of apple juice. However, fermentation decreased the total phenolic and flavonoid content. Subsequent LC-MS/MS analysis of the phenolic profile indicated that the content of 5-O-caffeoylquinic acid (5-CQA), quercetin, and phloretin with strong antioxidant activity was increased significantly after fermentation. The modified phenolic composition may contribute to the increased antioxidant activity of fermented apple juice. Our findings showed that Lactobacillus plantarum ATCC14917 fermentation may be an efficient way to enhance the bioavailability of phenolic compounds and to protect cells from oxidative stress.
