<p>Hypercholesterolemia is a risk factor for atherosclerosis and vascular diseases. Medicinal plants with different content of secondary metabolites such as polyphenols and flavonoids are natural sources to cope hypercholesterolemia. This study aimed to determine the effect of ethyl acetate fraction of piladang leaves (<em>Solenostemon scutellarioides</em> (L) Codd) on serum cholesterol levels in hypercholesterolemic male rats. Rats were divided into 6 groups, each consisting of 6 animals: group I (negative control), group II (positive control), group III, IV and V were each given fraction of ethyl acetate doses respectively 100, 250 and 500 mg/kg and group VI (simvastatin as a comparator). Measurement of serum cholesterol levels were conducted with CHOD-PAP method using a photometer 5010. Result showed ethyl acetate fraction affects cholesterol levels of experimental animals with a lower value than the positive control. According to statistics of one way ANOVA followed by the Duncan test method SPSS 17 showed no significant differences (p&gt; 0.05) on cholesterol levels in all given doses of ethyl acetate fraction. Group III(a dose of 100 mg / kg) was probably the most effective in lowering the blood cholesterol levels of experimental animals.</p>

The fruit of Rosa multiflora has been used as traditional herbal medicine in Asian countries. The present investigation was undertaken to study the antimicrobial activity and total polyphenol content of hexane, ether, ethyl acetate, water fraction of methanol extract of fruit and flower from Rosa multiflora and Rosa wichuraiana. Antimicrobial activity of the mentioned fractions against 3 gram-positive and 4 gram-negative bacteria using disk diffussion method. The measurement of minimal inhibition concentration (MIC) showed that the ethyl acetate fraction of the two Rosa species is the most effective against the tested bacteria. The total polyphenol content of ethyl acetate fraction of the two Rosa species is higher than the other fractions. The results indicate the antimicrobial activity was related with the total polyphenol content and the fruit and flower of the two Rosa species can be considered as a natural source of antimicrobial agents.

Treatment Of Diabetes

This study aims to find the treatment of diabetes using natural materials by exploring plants in the province of East Nusa Tenggara. his research was conducted out by extracting the Strychnos nitida G.Don stem using a method of maceration by ethanol 70%. Ethanol extract was then fractionated using n-hexane and ethyl acetate. Simplicia from maceration and fractionation results were then tested for antioxidant activity, α-glucosidase inhibition activity and identification of active compounds. The results showed that ethyl acetate fraction had the lowest IC50 value of 86.83 μg / ml. Results of the α-glucosidase activity test showed that ethyl acetate fraction and n-heksan fraction at 900 ppm had the highest percentage of inhibition of 34.23% and 33.89%. Identification using LCMS/MS method showed that ethyl acetate fraction consist of Benzenemethamine, N, N-dioctyl- as an antioxidantcompound and compound 24-methyl-5-cholestone-hexol as an antidiabetic compound. From the results of this study, we concluded that the extract of kayu ular Strychnos nitida G.Don stem has inhibition activity toward α-glucosidase enzyme.

Background: Microbial resistance to antibiotics is a global public health problem, which requires urgent attention. Platonia insignis is a native species from the eastern Brazilian Amazon, used in the treatment of burns and wounds. Objectives: To evaluate the antimicrobial activity of the hydroalcoholic extract of P. insignis (PIHA), the ethyl acetate fraction (PIAE), and its subfraction containing a mixture of biflavonoids (BF). Moreover, the effect of these natural products on the antibiotic activity against S. aureus strains overexpressing efflux pump genes was also evaluated. Methods: Minimal inhibitory concentrations were determined against different species of microorganisms. To evaluate the modulatory effect on the Norfloxacin-resistance, the MIC of this antibiotic was determined in the absence and presence of the natural products at subinhibitory concentrations. Inhibition of the EtBr efflux assays were conducted in the absence or presence of the natural products. Results: PIHA showed a microbicidal effect against S. aureus and C. albicans, while PIAE was bacteriosctatic for S. aureus. PIAE and BF at subinhibitory concentrations were able to reduce the MIC of Norfloxacin acting as modulating agents. BF was able to inhibit the efflux of EtBr efflux in S. aureus strains overexpressing specific efflux pump genes. Conclusion: P. inignisis a source of efflux pump inhibitors, including volkensiflavone and morelloflavone which were able to potentiate the Norfloxacin activity by NorA inhibition, being also able to inhibit QacA/B, TetK and MsrA. Volkensiflavone and morelloflavone could be used as adjuvant in the antibiotic therapy of multidrug resistant S. aureus strains overexpressing efflux pumps.
