Non‑alcoholic fatty liver disease (NAFLD) is an increasingly prevalent ailment worldwide. Moreover, de novo lipogenesis (DNL) is considered a critical factor in the development of NAFLD; hence, its inhibition is a promising target for the prevention of fatty liver disease. There is evidence to indicate that AMP‑activated protein kinase (AMPK) and sirtuin 1 (SIRT1) may play a crucial role in DNL and are the regulatory proteins in type 2 diabetes mellitus, obesity and cardiovascular disease. Therefore, AMPK and SIRT1 may be promising targets for the treatment of NAFLD. The present review article thus aimed to summarize the findings of clinical studies published during the past decade that suggested the beneficial effects of AMPK and SIRT1, using their specific activators and their combined effects on fatty liver disease.

Mitragyna is a genus belonging to the Rubiaceae family and is a plant endemic to Asia and Africa. Traditionally, the plants of this genus were used by local people to treat some diseases from generation to generation. Mitragyna speciosa (Korth.) Havil. is a controversial plant from this genus, known under the trading name “kratom”, and contains more than 40 different types of alkaloids. Mitragynine and 7-hydroxymitragynine have agonist morphine-like effects on opioid receptors. Globally, Mitragyna plants have high economic value. However, regulations regarding the circulation and use of these commodities vary in several countries around the world. This review article aims to comprehensively examine Mitragyna plants (mainly M. speciosa) as potential pharmacological agents by looking at various aspects of the plants. A literature search was performed and information collected using electronic databases including Scopus, ScienceDirect, PubMed, directory open access journal (DOAJ), and Google Scholar in early 2020 to mid-2021. This narrative review highlights some aspects of this genus, including historical background and botanical origins, habitat, cultivation, its use in traditional medicine, phytochemistry, pharmacology and toxicity, abuse and addiction, legal issues, and the potential of Mitragyna species as pharmaceutical products.

A research which identification of secondary metabolites and antibacterial activity test from methanol exstract of leaf Sungkai (Peronema canencens Jack) to several pathogens bacterial, which aims to identification of secondary methabolites and determine the antibacterial activity from crude methanol extract of leaf Sungkai (P. canencens Jack). against Streptococcus mutans, Salmonella thyposa, Bacillus subtilis and Staphylococcus aureus bacteria. Material test obtained by maceration with methanol, then tested for activity. Minimum Inhibition Concentration (MIC) value extract was determined by liquid dilution and the followed by scratches on solid media method. Minimum Kill Concentration (KBM) value extracts was determined by agar diffusion method with using paper disks.The results secondary metabolite identify form extracts of leaves P. canencens obtainable derived alkaloid, terpenoids - steroids, flavonoids, and tannin compounds. Methanol extract have the antibacterial activity. Minimum Inhibition Concentration (MIC) value of extract is concentration of 20% for bacteria S. mutans, S.thiposa and S.aureus, while for the B. subtilis is konsentration of 15%. Minimum Kill Concentration (KBM) values exstract at a concentration of 5% effective at killing S. mutans and S. thyposa bacteria, while the concentration of 1% effective to bacteria B.subtilis and S.aureus. Key words: P. canencens Jack, antibacteria activity, S. mutans, S. thiposa, B. subtillis, S. aureus ABSTRAK Telah dilakukan penelitian identifikasi metabolit sekunder dan aktivitas antibakteri ekstrak metanol daun Sungkai (P.canencens Jack) terhadap beberapa bakteri patogen. Penelitian ini bertujuan untuk mengidentifikasi metabolit sekunder dan mengetahui aktifitas antibakteri dan Kadar Hambat Minimum (KHM) dan Nilai Kadar Bunuh Minimum (KBM) ekstrak kasar metanol daun Sungkai (P.canencens Jack.) terhadap bakteri Streptococcus mutans, Salmonella thyposa, Bacillus subtilis dan Staphylococcus aureus.

Piper betle var. nigra is a tropical plant closely related to the common piper. P. betle has also been dubbed a promising source of natural antioxidants in herbal health products, antibacterial, antifungal, antimalarial, cytotoxic activity against the cancer cell lines K562 and HL-60, and antileishmanial. The aim of this study to observation Antimicrobial activity and isolation of chemical compound. The antimicrobial activity of P. betle extract was performed by well diffusion method against two oral pathogenic bacteria (Streptococcus mutans and Streptococcus sanguinis) and opportunistic pathogenic yeast (Candida albicans). The inoculum (bacterial and yeast suspension) was prepared from a 24-h culture on NB for bacterial suspension and on TSB for yeast suspension. Extraction and isolation using various method of chromatography. Isolated compounds were characterized by spectroscopic means. Our study showed antimicrobial activity from crude ethanol extract of leaves P. betle L. var. nigra against two oral pathogenic bacteria and opportunistic pathogenic yeast with concentration 0.5% and 1%. The first report of two new amides derivatives, piperenamide A (1) and piperenamide B (2) in P. betle L. var. nigra.

Research of potential antifungal Candle bush’s leaf extract (Cassia alata L.) have been done. The research done by the method of extraction by maceration using methanol solvent and continued by fraksinasi. Extract get a tes to know potential the antifungal with diffusion method and used a paper disc in different consentration. Analysis of the test is done by measuring the diameter of the zones of fungal growth inhibitory extract. The result of antifungal activity test shows that Candle bush’s leaf has antifungal activity against M. furfur
