Abstract

Ekstrak daun sirsak (Annona muricata) mengandung antioksidan seperti flavanoid, acetogenins yang memiliki peran sebagai antiplasmodium secara in vitro. Penelitian ini bertujuan menguji pengaruh ekstrak etanol daun sirsak terhadap penurunan kadar Tumor Necrosis Fakctor-alpha (TNFα) dan peningkatan kadar Nitric Oxide (NO) pada limpa mencit Swiss betina yang diinokulasi Plasmodium berghei ANKA. Desain penelitian ini adalah Post Test only randomized Control Group Design. Sampel terdiri dari mencit Swiss normal (K-), mencit yang diinokulasi P. berghei ANKA (K+), mencit yang diberikan ekstrak daun sirsak 100 mg/KgBB/hari (P1), mencit yang diberikan ekstrak daun sirsak 200mg/KgBB/hari (P2), mencit yang diinokulasi P. berghei ANKA dan diberikan ekstrak 100mg/KgBB/hari (P3), mencit yang diinokulasi P. berghei ANKA dan diberikan ekstrak 200mg/KgBB/hari (P4). Rerata kadar TNFα kelompok P4 lebih rendah di banding kelompok yang lain (X=403,88). Uji Bonferroni kelompok P4 berbeda bermakna (p=0,04). Rerata kadar NO kelompok P3 (0,93) lebih tinggi dibanding K(+) dan P4. Hasil uji Mann whitney menunjukkan bahwa kadar NO berbeda bermakna antara K(+) dengan K(-), K(+) dengan P1, K(+) dengan P2, K(-) dengan P4, P1 dengan P4, P2 dengan P4. Hasil uji korelasi Spearmen Rank antara kadar TNFα dan NO menunjukkan adanya korelasi (p <0,05).

Abstract

Background: Consumption of high-fat diet (HFD) is increasing blood total cholesterol, LpPLA2 enzyme and MDA level which is a cause of atherosclerosis that should be controlled by antioxidants. Paddy straw mushroom (Volvariella v.) extract has an antioxidant compounds. This research proves the effect of Volvariella v. extract on blood total cholesterol (TC), LpPLA2 enzyme and MDA level, and proves correlation between TC with LpPLA2 enzyme and MDA level.Methods: A randomized post test only control group design to twenty four of 8-10 weeks old  male Rattus novergicus Wistar strain with 180-200 gram were divided into four group; K1 with standard diet, K2 with HFD, each X1 and X2 with HFD+Volvariella v. extract 500 mg/kg.bwt/day and 1000 mg/kg.bwt/day. All treatments for 56 days. TC levels assesed by enzymatic colorimetric test method, LpPLA2 enzyme with ELISA method and MDA with TBARs method. Data were analyzed by one way Anova, LSD post hoc and Pearson’s correlation.Results: TC mean of K1 (91,28±1,55 mg/dL), K2 (181,96±4,19 mg/dL), X1 (122,94±2,75 mg/dL) and X2 (105,86±2,25 mg/dL); p=0,001. Enzyme LpPLA2 mean of K1 (2,65±3,19 ng/mL), K2 (1,29±1,35 ng/mL), X1 (3,92±2,18 ng/mL),  X2 (2,05±3,29 ng/mL); p=0,385 and blood MDA mean of K1 (1,17±0,12 nmol/mL), K2 (5,75±0,21 nmol/mL), X1 (2,96±0,91 nmol/mL) and X2 (1,77±0,92 nmol/mL); p=0,001. Correlation between TC and LpPLA2 enzyme was shown by X1 group (p=0,042; r = - 0,827).Conclusion:Volvariella v. extract decreased blood total cholesterol and MDA level significantly, did not significant to LpPLA2 enzyme. There wss a correlation between TC and LpPLA2 enzyme but was not to TC and blood MDA.

Abstract

Background: Several studies focused on phytochemical as agents of cancer prevention and co-chemotherapy. One of Indonesian plant which has edible fruit but it hasn’t been completely explored is Medinilla speciosa (Reinw.ex Bl.). Objective : The aim of this study is to examine the cytotoxic activity (IC50 value) of Medinilla speciosa (Reinw.ex Bl.) fruit ethanolic extract. Methods : Medinilla speciosa (Reinw.ex Bl.) fruit ethanolic extract was used in this study. The cytotoxic activity was investigated in vitro on human breast cancer T47D cell-line. The cells viability were assessed using MTT colorimetric assay. Breast cancer T47D cell lines was treated with fruit ethanolic extract (10, 25, 50, 100, 250, 500 and 1000 µg/ml) for 24 hour of incubation. This study also identified phytochemical compound of the fruit with thin layer chromatography (TLC). Results: The result showed that ethanolic extract of Medinilla speciosa (Reinw.ex Bl.) has moderate cytotoxicity on breast cancer T47D cell line with IC50 value of 614.50 µg/ml and yield the decrease of cell viability at higher concentration. Medinilla speciosa fruit can not be used as anticancer agent but chemoprevention agent. Phytochemical test showed that the fruit extract contain flavonoid and saponin compound. Conclusion: Ethanolic extract of Medinilla speciosa fruit exhibited moderate cytotocicity on breast cancer T47D cell lines with IC50 value was 614,50 µg/ml thus it can be used as chemopreventioan agent.
