“…The high correlation suggested that the antioxidant capacity of leaf, stem, latex, and bark extracts could be possibly due to the presence of saponins, flavonoids, and flavonols. The results obtained from the present study were supported by various reports that described the important relationships between the phytocompounds and antioxidant assays [65][66][67].…”

This study aims to investigate the phytochemical content and antioxidant activity of the leaf, stem, latex, and bark of Euphorbia neriifolia (EN) Linn. using the solvent extraction method with petroleum ether, benzene, chloroform, ethyl acetate, methanol, and aqueous extracts. Total tannin content, total saponin content, total flavonoid content, total phenol content, and total flavonol content were investigated using spectrophotometric equivalents of the standards, tannic acid, quillaja, quercetin, gallic acid, and rutin, respectively. The EN extracts of various parts were screened for potential antioxidant activities by hydrogen peroxide scavenging assay (H 2 O 2 ), ferric ion reducing antioxidant power assay (FRAP), 2,2-diphenylpicrylhydrazyl assay (DPPH), metal chelation assay, nitric oxide (NO), and superoxide (SO) scavenging methods. The quantitative analysis of phytochemicals from EN revealed the presence of tannins, saponins, flavonoids, phenols, and flavonols in considerable amounts. The in vitro antioxidant assay of EN determined that the leaf, stem, latex, and bark have prominent antioxidant potential. The results showed that all the plant parts possessed antioxidant properties which were strongly correlated with the phytoconstituents. From the present study, it can be concluded that the mean content of phytochemicals in the case of EN leaf is greater than the stem, latex, and bark of the plant and this may have contributed to its great antioxidant properties. This may also justify the frequent use of the leaf more than the stem, latex, and bark in the traditional medicinal systems for the cure of bronchial infections, abdominal swellings, inflammation, pain, and tumor.

“…The responses of TPC and AC of the chestnut peel extracts are shown in Table 2. The lowest values were obtained with pure ethanol and methanol, which is in agreement with previous studies (Ashraf et al, 2016;Riciputi et al, 2018;DiNardo et al, 2019;Lasano et al, 2019). Results showed that the highest value of TPC (41.92 mg GAE/g DM) was achieved with ethanol, which is in concordance with the result of Stevigny et al (2007), while the highest value of AC (42015.95 mmol AAE/100 g DM) was obtained with methanol.…”

In the present work, solvent concentration, extraction time, and solid to solvent (S/S) ratio were evaluated in order to recover the majority of polyphenols from chestnut peel waste using ethanol and methanol. Extraction method for polyphenols from peel pre-treated by ohmic heating (OH) was optimised using response surface methodology (RSM). The effect of these independent variables on total phenolic content (TPC) and antioxidant capacity (AC) was studied using Box-Behnken Design (BBD). A second-order polynomial model provided a satisfactory fit to the experimental data with a high coefficient of determination (R2) value. Results showed that S/S ratio and solvent concentration were generally significant variables during extraction in terms of TPC and AC. The optimum extraction conditions were obtained as 1/10 of S/S ratio and 60% of solvent concentration for both solvents. As the optimum extraction time, 82.41 min for ethanolic extraction and 116.97 min for methanolic extraction were selected. Under these optimal conditions, TPC values of the ethanolic and methanolic extracts were found to be 39.02 and 38.79 mg gallic acid equivalents per gram of dry matter (mg GAE/g DM), respectively, thus indicating highly close agreement to the predicted values. Consequently, the effectiveness of the solvents used was found to be very similar to each other. The OH pre-treatment appeared to be a promising technique for polyphenolic extraction from industrial wastes.

“…Besides, it also contains higher isoflavones and total phenolic content (TPC) than M. pajang (bambangan) and M. foetida (Ikram et al, 2009), while possessing excellent antioxidant activity (Lasano et al, 2019a). Additionally, the by-products of M. odorata, particularly the seed kernel, has been reported to possess high amounts of essential nutrients, and exhibited substantial α-amylase and α-glucosidase inhibitory properties (Lasano et al, 2019b).…”

Mangifera odorata, or known as “kuini” in Malay, is considered an underutilised climacteric tropical fruit. Recent studies had suggested that the by-products of M. odorata may serve as functional food ingredients based on their nutritional values and biological activities. Thus, the present work was aimed to determine the nutritional composition, antidiabetic properties through α-glucosidase and α-amylase inhibition assays, and phytochemical profiling of M. odorata pulp using ultra-high-performance liquid chromatography-electrospray ionisation orbitrap tandem mass spectrometry (UHPLC-ESI-Orbitrap-MS/MS). Proximate analyses found that M. odorata pulp contained high amounts of soluble fibre and moisture. The main sugar in the pulp was identified as sucrose, while ß-carotene, potassium, calcium, iron, and zinc were the major vitamins and minerals. The extraction of the sample in water, acetone, methanol, and ethanol were performed for the determination of antidiabetic assay. The results showed that 60% of ethanolic extract had the highest α-amylase inhibitory activity among the four extraction solvents. The findings revealed high levels of mangiferin in the active extract, which may be responsible for the α-amylase inhibition activity, thus contributing to lower post-prandial blood glucose. The present work provides evidence on the nutritional benefits of M. odorata pulp, as well as the potential use of its ethanolic extract as an α-amylase inhibitor.
