ABSTRACT Chrysophyllum cainito L. is a plant which empirically used as traditional medicine. The pharmacological effect of C. cainito is caused by secondary metabolite activity contain in the leaves. The aim of this research was to know the metabolites profile in n-hexane extract, ethyl acetate extract, and methanol extract of C. cainito leaves using UPLC-QToF-MS/MS. Dried powder of C. cainito leaves was extracted with n-hexane, ethyl acetate, and methanol with gradual extraction using Ultrasonic Assisted Extraction (UAE). Each extract was prepared with methanol and DCM solvent then injected 5 µl into UPLC-QToF-MS/MS and analyzed with Masslynx 4.1 softwares and Chemspider. The result showed that there were 28 compounds from n-hexane extract with diethyltoluamide as major compound, 47 compounds from ethyl acetate extract with loliolide as major compound, and 34 compounds from methanol extract with eplerenone as major compound. Based on literature study, there were also several compounds that likely having activity as phytoestrogens. Keyword: Metabolite profiling, chrysophyllum cainito L., UPLC QToF-MS/MS     ABSTRAK Chrysophyllum cainito L. merupakan tumbuhan yang secara empiris digunakan sebagai obat tradisional. Efek farmakologi tersebut disebabkan adanya aktivitas dari berbagai senyawa metabolit sekunder yang terkandung dalam daun C. cainito. Tujuan dari penelitian ini untuk mengetahui profil metabolit ekstrak n-heksana, ekstrak etil asetat, dan ekstrak metanol daun C. cainito menggunakan UPLC-QToF-MS/MS. Serbuk kering daun C. cainito diekstraksi secara bertingkat menggunakan n-heksana, etil asetat, dan metanol dengan metode UAE. Masing-masing ekstrak dipreparasi dengan metanol dan DCM lalu diinjeksikan sebanyak 5 µl ke dalam UPLC-QToF-MS/MS, kemudian dianalisis dengan software Masslynx 4.1 dan Chemspider. Hasil menunjukkan profil metabolit dari masing-masing ekstrak daun C. cainito, yaitu ekstrak n-heksana dengan 28 senyawa dan diethyltoluamide sebagai senyawa mayor, 47 senyawa terkandung dalam ekstrak etil asetat dengan senyawa mayor loliolide, dan 34 senyawa terkandung dalam ekstrak metanol dengan senyawa mayor yaitu eplerenone. Dari studi literatur diketahui terdapat beberapa senyawa yang memiliki aktivitas sebagai fitoestrogen. Kata Kunci: Metabolite profiling, Chrysophyllum cainito L., UPLC QToF-MS/MS

Diabetes mellitus (DM) is a progressive metabolic disease that continues to increase every year. Treatment therapy using oral hypoglycemic drugs to treat DM has side effects, and alternative approaches must be taken. Abelmoschus esculentus has been known to be used as an alternative to DM because it has antioxidant activity due to its high flavonoid content. The purpose of this study was to determine the antidiabetic activity of 96% ethanol extract of Okra leaves against male mice of balb-c strain. Male mice were acclimatized for seven days and divided into five test groups and then fasted for 18 hours. Then the mice were induced with 150 mg / 20 g BW alloxan and measured on the 3rd day. Ethanol extract 96% okra leaves were then given in a dose of 5.6 mg / 20g BW; 11.2 mg / 20g BW; 22.4 mg / 20g BW, CMC Na 0.5% as negative control and glibenclamide 0.026 mg / 20g BBs as positive control for 14 days. The results of therapy with 96% ethanol extract of okra leaves can reduce blood glucose levels in mice so that the okra leaves contain flavonoid compounds that have antioxidant activity and can reduce blood glucose levels.

Marsilea crenata Presl. leaves contain phytoestrogens that is suspected to play a role in increasing bone formation. Bone formation activity is defined by the expression of Osterix, a transcription factor that plays a key role in bone development. The aim of this study is to show that the ethyl acetate fraction of Marsilea crenata Presl. leaves can increase bone formation process in hFOB 1.19 cells in a TNF-α dependent manner, by measurement of Osterix. The hFOB 1.19 cells were grown in 24-well microplates and treated with 10 ng/ml TNF-α for 24 hours. The ethyl acetate fraction of Marsilea crenata Presl. leaves were also added in concentrations of 62.5, 125, and 250 ppm. A positive control was employed, at a concentration of 2.5 g/L of genistein. The expression of osterix was examined using an immunocytochemistry technique with CLSM to assess bone forming activity. The results show that ethyl acetate fraction Marsilea crenata Presl. leaves can boost osterix expression in hFOB 1.19 cells, with optimal concentration was 250 ppm at p<0.005. The ethyl acetate fraction of Marsilea crenata Presl. leaves can increase Osterix in osteoblast hFOB 1.19 cell, indicating improved bone forming activity.

Banana peel is a material that can be used as a natural antibacterial because of its secondary metabolites content. The present study aimed to evaluate antibacterial activity of ethanol 96% extracted from banana (Musa paradisiaca L) peel against Escherichia coli. Result of phytochemical screening indicated that banana peel extract has alkaloid, flavonoid (tannin), and saponin compound that can act as antibacterial. Banana peel extract showed antibacterial activity that was proved by clear zone formed around disk paper. Sample of 64% extract concentration had the largest inhibition zone (9.6 mm) compared to sample of 16% and 32% concentration, inhibition zone of which was 4.4 mm and 6.26 respectively. One Way Anova analysis showed that sample of 64% concentration was significantly different from negative control, 16%, and 32% concentration. Nevertheless, there was no significant difference between 16% and 32% concentration.
