Abstract

Lovastatin is an anti-cholesterol agent that was produced by Aspergillus terreus using solid state fermentation (SSF). During this fermentation process, sulochrin is also produced as an unwanted co-metabolite. However, our previous result showed that sulochrin had potential as antidiabetes because it is an inhibitor agent of α-glucosidase. In this paper, we reported our observation on lovastatin and sulochrin production pattern in relation with inhibitor α-glucosidase activity during eleven days fermentation of A. terreus koji (SSF) ethyl acetate extract. Koji obtained from solid state fermentation with rice as the substrate and incubated at room temperature, sample is taken daily for eleven day (D-1 to D-11). Lovastatin and sulochrin production was measured by Liquid Chromatography- Mass Spectrometer based on their molecular weight m/z 404.5 and 332.3 respectively. The inibitory activity is measured by inhibition model of koji extract against α-glucosidase (EC 3.2.1.20) from Saccharomyces cereviceae. The results show that lovastatin production was started on the day 2 (0.04 mg/g) and achieving the optimal production on day 7 (11.46 mg/g), while sulochrin production was started on day 4 (0.60 mg/g) and keep produced until the end of fermentation period at Day 11 (3.11 mg/g). Koji extract was started to show inhibitory to α-glucosidase activity on Day 5 (IC50= 23.34 μg/mL) and keep showed activity until Day 11 (IC50=3.33 μg/mL). These results suggest that inhibitory activity of koji extract to α- glucosidase activity have relation with sulochrin biosynthesis production.

Abstract

Clerodendrum minahassae (Lamiaceae) merupakan tumbuhan yang berasal dari Sulawesi Utara dan dikenal dengan nama leilem. Pada umumnya genus Clerodendrum mengandung senyawa antioksidan seperti senyawa-senyawa fenol dan flavonoid. Penelitian ini bertujuan untuk menentukan aktivitas antioksidan dan toksisitas serta kandungan senyawa fenol dan flavonoid total dari daun leilem. Ekstrak daun leilem dibuat secara maserasi dalam metanol yang selanjutnya difraksinasi dengan n-heksana dan etil asetat. Aktivitas antioksidan diuji dengan metode penangkapan radikal bebas DPPH (1,1-difenil-2-pikrilhidrazil) dan toksistas diuji terhadap larva Artemia salina dengan metode BSLT (Brain Shrimp Lethality Test). Kandungan fenol dan flavonoid dilakukan dengan metode kolorimetri. Hasil penelitian memperlihatkan ekstrak metanol dan fraksi etil asetat daun leilem memiliki aktivitas antioksidan lemah dengan nilai IC50 300,57 µg/ml dan 189,62 μg/ml, sementara itu toksisitas terhadap larva udang Artemia salina diperlihatkan oleh ekstrak metanol dan fraksi etil asetat daun leilem dengan nilai LC50 berturut turut 190,58 μg/ml dan 147,36 μg/ml. Penentuan kadar fenol total dan flavonoid total dilakukan pada fraksi etil asetat dengan menggunakan standar asam galat untuk fenol total dan kuersetin untuk flavonoid total. Hasil penentuan menunjukkan bahwa fraksi etil asetat daun leilem mengandung fenol total 164,38 mg/g ekstrak dan flavonoid total 270,8 mg/g ekstrak.

Abstract

Petai mistletoe (Dendrophthoe praelonga (Blume) Miq) is semi-parasitic plant. Parasite plant has been used traditionally in Indonesia to prevent or treat degenerative diseases, such as cancer. The purpose of this study was to indentify anticancer compound of petai mistletoe leaves extract and to examine its antioxidant activity (based on DPPH method) and cytotoxic activity on breast cancer (MCF-7) cell lines in vitro using Alamar blue method. This research aims to isolating, characterize, determine antioxidant activity and cytotoxic activity. Separation was conducting column chromathography and characterize was conducted using TLC, FT-IR, LC-MS and NMR-1D. From the result obtained, the isolated compound is flavonol quercetine (3,3,7,3’,4’ pethahydroxyflavone) which active antioxidant with IC50 value of 9.4 μg/mL and the value of cytotoxic activity with IC50 750.62 μg/mL

Abstract

Ebony (Diospyros celebica. Bakh) is a native plant of Indonesia that is used as a traditional medicine for diabetes mellitus. Previous studies state that ethanol extract from ebony leaves significantly reduced blood glucose levels of diabetic rats induced by alloxan. This ability is thought to be caused by secondary metabolites which is phenolic and flavonoid compound. However, research related to structure compounds in extract and composition of solvent variations in the extraction process to get the most optimal activity and also their correlation with total phenolic and flavonoid compounds has not been carried out. This study aimed to evaluate the composition of the optimum solvent in the extraction process and also to know the structure compounds contained in the extract. In the present study, we extracted the ebony leaves with three solvents of different polarity (ethanol-water), i.e. ethanol 50% (EtOH), EtOH 70%, and EtOH 96%. Quantitative estimation of total phenolic and flavonoid contents. These extracts were future evaluated for their activity and the content of compounds in the extract was identified using LCMS/MS. The results showed that phenolic compounds that have been identified in ebony leaf extract are methyl gallate and (-)-Epiafzelechin 3-gallate and we found there were significant differences in all test parameters between the three extracts which is EtOH 96% extract gave the best.
