“…There has been various research on natural in-gredients to control various types of early inflammation-related factors and treat systemic inflammatory responses by inhibiting the secretion of inflammatory mediators. Ethanol extracts from graviola leaves have been shown to inhibit the secretion of NO and cytokines (e.g., IL-6, TNF-α, and IL-1β), which are inflammatory mediators with anti-inflammatory effects [9].…”

Background: Graviola (Annona muricata) is known to have a superior cancer cell killing effect than adriamycin, a chemical drug, and is used in hospitals. Check to see if it actually has an anti-inflammatory effect on the skin.Objective: This study was conducted to assess the anti-inflammatory and molecular effects of A. muricata leaf extract to evaluate its potency as a cosmetic ingredient and value in the cosmetic industry. Methods:The anti-inflammatory effects of A. muricata were evaluated using an ethanolic extract of its dried leaves. To assess the inhibitory effects of A. muricata extract on nitric oxide (NO) production, the amount of NO produced in RAW 264.7 cells induced by lipopolysaccharides (LPS), an inflammatory mediator, was measured. Results:The experiment using the A. muricata leaf extract did not show a significant level of cytotoxicity at all concentration of the extract, and the survival rate of RAW 264.7 cells was low only at high concentrations of the extract. Assessment of the antiinflammatory effects of A. muricata leaf extract showed that a significant amount of NO production was inhibited in the cells compared to that when the leaf extract was incubated with LPS. Conclusion:A. muricata leaf extract would be an excellent candidate as a cosmetic ingredient with its anti-inflammatory properties and other functions.

“…3). The initially high polyphenol and flavonoid contents of the shoots and leaves reportedly decrease as growth proceeds, with the former decreasing more rapidly than the latter (Cho et al, 2018;Im et al, 2013). Lee et al (2011) reported that the polyphenol content of mulberry tree leaves was higher than that of the stems.…”

The goal of this study was to provide basic data for various parts of Rhus verniciflua (R. verniciflua), and based on these data, to suggest the parts thereof that may be used as food material along with the xylem. Analysis of the proximate compositions revealed that the leaves contained mainly carbohydrates; the shoots crude protein; and the stems and seeds contained mainly crude fiber. All these parts were found to be rich in potassium and magnesium in terms of their mineral content. The total urushiol content was the lowest in the seeds at 0.92 mg/100 g. The total polyphenol and flavonoid content were highest in the shoots and leaves, respectively. Physicochemical analysis indicated that the seeds may be used as a food material, along with the xylem. According to DPPH and ABTS scavenging activity analysis, 50% ethanol was considered appropriate as a solvent for seed extraction. Cytotoxicity analysis of the seeds extracted with 50% ethanol confirmed that none of the components were present at cytotoxic levels. The findings of this study provide basic information regarding the use of R. verniciflua seeds as a food source.

The prevention of oxidative damage is important because it can lead to various disease conditions, such as hyperlipidemia, hypertension, and arrhythmia. Research on the protective effects of natural substances on H2O2treated H9c2 cells has been widely reported. However, little information is available on the preventive effect of Allomyrina dichotoma larva extract (ADLE) on oxidative damage. In this study, we investigated whether ADLE pretreatment has an antioxidative effect on H2O2-treated H9c2 cells. An MTT assay showed ADLE was non-cytotoxic and when co-treated decreased H2O2-induced cell death. DPPH and ABTS assays showed ADLE dose-dependently increased antioxidant activity, and FRAP assays showed ADLE increased reducing power. Furthermore, western blot revealed ADLE increased the level of proteins associated with apoptosis and antioxidant activity, and CAT and SOD assays showed their enzyme levels were higher in ADLE and H₂O₂ co-treated H9c2 cells than in H₂O₂-treated cells. The study shows that ADLE pretreatment prevents oxidative damage to H9c2 myocardial cells and has potential use as a functional material.
