Inflammatory disorders are linked to the pathogenesis of several diseases. Limitations posed by synthetic anti-inflammatory agents had inspired the need to source for more effective and safer natural alternatives. This study evaluated the anti-inflammatory activities of the twig extracts and fractions of Jatropha Curcas (J. curcas) and also identify the phytocompounds responsible for its anti-inflammatory activities. The methanol/methylchloride extract of J. curcas twig was fractionated into n-hexane, ethyl acetate and butanol fractions. The effects of extracts and fractions of J. curcas twig on xylene induced topical inflammation were evaluated. HPLC and LC-MS of the promising fraction was evaluated. Results showed that the extract exhibited high anti-inflammatory activity at 500 µg/ear (66%) and 250 µg/ear (51%) compared to the positive control, piroxicam with 45% inhibition at 250 µg/ear. Ethyl acetate fraction significantly (p<0.05) suppressed the development of xylene ear edema compared to Piroxicam. HPLC of the fractions revealed the anti-inflammatory phytocompounds; pinoresinol, orientine, quercetin, septicin and naamin F. LC-MS analysis mass spectra showed mass peaks [M-H]-of m/z 299.4, 599.1 and [M+H]+m/z 301 which represents a mass of 300 of an unknown compound. These findings suggest that the twigs of J. curcas possess promising anti-inflammatory phytocompounds which justify its use in the management of inflammatory conditions in traditional medicines.

Column chromatography of the dichloromethane fraction from an aqueous methanolic extract of fruit peel of Citrus pyriformis Hassk. (Rutaceae) resulted in the isolation of seven compounds including one coumarin (citropten), two limonoids (limonin and deacetylnomilin), and four sterols (stigmasterol, ergosterol, sitosteryl-3-β-D-glucoside, and sitosteryl-6ʹ- O-acyl-3-β-D-glucoside). From the ethyl acetate fraction naringin, hesperidin, and neohesperidin were isolated. The dichloromethane extract of the defatted seeds contained three additional compounds, nomilin, ichangin, and cholesterol. The isolated compounds were identified by MS (EI, CI, and ESI), 1H, 13C, and 2D-NMR spectral data. The limonoids were determined qualitatively by LC-ESI/MS resulting in the identification of 11 limonoid aglycones. The total methanolic extract of the peel and the petroleum ether, dichloromethane, and ethyl acetate fractions were screened for their antioxidant and anti-inflammatory activities. The ethyl acetate fraction exhibited a significant scavenging activity for DPPH· free radicals (IC50 = 132.3 μg/mL). The petroleum ether fraction inhibited 5-lipoxygenase with IC50 = 30.6 μg/mL indicating potential anti-inflammatory properties. Limonin has a potent cytotoxic effect against COS7 cells [IC50 = (35.0 ± 6.1) μM] compared with acteoside as a positive control [IC50 = (144.5 ± 10.96) μM]

BACKGROUND: Nutmeg (Myristica fragrans H.), one of native plants of Maluku Indonesia, has long been used as traditional medicines especially to treat tumors, externally to treat skin infections. M. fragrans also has important biological activities as anticancer. However, antimelanoma activity of M. fragrans remains unknown. The aim of this study is to compare M. fragrans extracts as anticancer on melanoma B16-F10 cells by inducing apoptosis.METHODS: M. fragrans seed was extracted with ethanol then fractionated with n-hexane, ethyl acetate, and n-butanol. B16-F10 melanoma cells were cultured and treated with various doses and tested using resazurin reduction assay. Apoptosis signalling via caspase-3 was measured by using western blot.RESULTS: The extract and fractions of M. fragrans reduced viability of cells with IC50 value for ethanol extract 21.83 µg/mL, ethyl acetate fraction 21.66 µg/mL, n-hexane fraction 47.53 µg/mL, and n-butanol fraction >1,000 µg/mL. The active fraction of ethyl acetate induced apoptosis via caspase-3 proteins similar with cisplatin as positive control in B16-F10 cells at 10 hours treatment.CONCLUSION: Taken together, M. fragrans ethyl acetate fraction has the highest IC50 than n-hexane and n-butanol fractions that significantly inhibited B16-F10 cell proliferation by inducing apoptosis via caspase-3. It provides the insight that it has the most potential activity as a chemopreventive agent for addressing melanoma skin cancer.KEYWORDS: M. fragrans, apoptosis, fraction, melanoma

ABSTRACT Background: Recent studies showed that Interleukin-8 (IL-8), activated cytokine immune response which plays an important role in the development of acute and chronic gastritis. Harmless anti-inflammatory therapeutic alternatives have been proposed, for example, the consumption of Sechium Edule Jacq. Swartz (chayote). Antioxidant (flavonoid) and cell regeneration (alkaloid) agents were found in chayote. This study aimed to determine the effect of chayote Sechium Edule Jacq. Swartz extracts on the level of IL-8 in Wistar rats with aspirin- induced gastritis. Subjects and Method: This was a randomized controlled trial (RCT) conducted at the laboratory of Mathematics and Natural Science, Universitas Sumatra Utara from January to February 2020. A total of 35 male Wistar rats was selected for this study and randomly allocated into 7 groups: (1) Negative control; (2) Positive control; (3) 100 mg/ kg BW chayote ethanol extract ; (4) 200 mg/kg BW chayote ethanol extract; (5) 100 mg/ kg BW chayote ethyl acetate fraction; (6) 200 mg/kg BW chayote ethyl acetate fraction; and (7) 20 mg omeprazole. The rats in positive control and treatment groups were induced with aspirin (200mg/ kg BW). The negative control group received no intervention. The dependent variable was level of IL-8 measured by ELISA. The independent variables were treatment status. The data were analyzed by One Way Anova and post hoc test. Results: The mean differences of IL-8 level were not statistically significant between study groups (p= 0.327). Mean of IL-8 level was higher in positive control group (Mean= 160.80; SD= 6.90) than in negative control group (Mean= 141.20; SD= 10.98). The lowest IL-8 level was in 100mg/ kg BW chayote ethanol extract group (Mean= 149.94; SD= 40.4), followed by 200mg/ kg BW (Mean= 152.4; SD= 30.73) and 100mg/ kg BW (Mean= 164.60; SD= 25.04) chayote ethyl acetate fraction groups, 20 mg omeprazole group (Mean= 170.60; SD= 21.58), and 200 mg/ kg BW chayote ethanol extract group (Mean= 176.80; SD= 10.98). Conclusion: The low dose (100mg/ kg BW) chayote ethanol extract has the most potential antiinflammation effect on in vitro gastritis with the lowest IL-8 level of all doses of chayote ethanol extract, chayote ethyl acetate fraction, and omeprazole.

Hedyotis diffusa Willd and Scutellaria barbata D. Don (HDSB) were the core couplet in medicines that were commonly used for the purpose of anti-inflammation and anticancer treatments in China. However, biological properties of this couplet have not been fully elucidated. In this study, we screened fractions of HDSB for their anti-inflammatory activities and explored pertinent molecular mechanisms on murine macrophage RAW264.7 cell model. Ethyl acetate fraction from the aqueous extract of the couplet at equal weight ratio (EA11) showed the strongest inhibition of the nitrite accumulation in supernatant of RAW264.7 cells stimulated with lipopolysaccharide (LPS)/interferon-γ (IFN-γ). In addition, EA11 inhibited iNOS and IL-1β expression in a concentration-dependent manner while promoting the expression of HO-1 and PPAR-γ. Anti-inflammatory capability is most likely facilitated by its inhibitory effect on JNK signaling pathway and miR-155 expression. This study suggests that EA11 may be represented as a potential anti-inflammatory therapeutic candidate.
