A. paniculata is a plant that can be used to overcome the disease diabetes. In DM there is a possibility of the use of therapy with oral hypoglycemic drugs, for example: metformin. This research was conducted using a complete random method indirectional pattern. This study aims to determine the potential of the combination of purified extract of sambiloto herbs and enhancement effects of metformin on blood glucose levels decrease in insulin resistant rats. Test animals used were divided 4 groups, group 1: metformin 45 mg / kg (positive control), group 2: purified extract of sambiloto herbs 434.6 mg/ kg, group 3: a combination of metformin 45 mg / kg BW with the extract of 434.6 mg/ kg (combination 1), and group 4: metformin 22.5 mg/ kg body weight with extract 434.6 mg/ kg (combination 2). Test animals are insulin resistant type 2 DM was made by administering 1.8 g fructose / kg body weight and fat diet for 50 days. Assay of glucose using a reagent kit. Observation of GLUT-4 expression in muscle cells by using immunohistochemical techniques. Insulin resistance rats was tested by using three parameters: (1) testing of blood glucose levels preprandial and postprandial (2) the hypoglycaemic activity of glibenclamide, and (3) observations of GLUT-4 protein expression in muscle tissue. Test results show that the animals had insulin resistant. Results, in this research antidiabetic activity assay indicate that the hypoglycaemic for combination 1 and combination 2 lower compared to a single administration of metformin or purified extract (p<0,05). From the above results concluded that the combination of sambiloto extract purified with metformin does not increase the potency of antidiabetic in single use.

The form of liposome formulations is one of strategies to overcome the limitations of anthocyanin extract stability of roselle calyx (Hibiscus sabdariffa L.). In this study, antioxidant comparative analysis of antioxidant activity and total anthocyanin content from rosella extract and its liposomes form was conducted. Preparation of extract made by maceration using the best solvent consisted of methanol : formic acid (97:3) (v/v). From this procedure, the obtained extract was about 26.40% and antioxidant activity was 19.99%. Liposome formulations of methanol extract from roselle calyx were prepared by reverse phase method using rosella extract as aqueous phase and egg lecithin as the lipid phase. The stability of exctract and liposome form of rosella calyx was compared. The stability study showed that there was a reduction of antioxidant activity (DPPH test) 11.25 % for the roselle extract, while the liposome form was 0.93% after 30 days storage in low temperature (0-50C) and saturated nitrogen. In addition, total anthocyanin content (pH differential method test) decreased approximately 39.12 % for the roselle extract and 0.72% for the liposome form. More over, the liposome had lower level of irritation than the form of extract. Therefore, it can be concluded that anthocyanin encapsulated by liposome was more stable, safe, and effective than the anthocyanin of the rosella calyx extract.

Free radical induced oxidative stress that influences the occurrence of various degenerative diseases such as cancer, coronary heart disease and premature aging. In the case that body's antioxidant defense system does not have excessive antioxidants, additional natural antioxidant via food or other nutrients intake is needed. Stems of ferns are known to contain phenolic compounds that are known to have antioxidant activity. A study has been carried out to determine antioxidant potential of stems of ferns of western Borneo origin compared to quercetin as positive control. Initially, material was macerated gradually with wasbenzen followed by methanol. The extract obtained was filtered and evaporated to dryness to give dried wasbenzen extract and methanol extract respectively. Antioxidant properties of extracts were performed by DPPH on TLC. Active (wasbenzen) extract was then partitioned with 80% methanol to give soluble and insoluble fractions. Active (insoluble) fraction was further fractionated by vacuum liquid chromatography using a gradient mobile phase with increasing polarity (wasbezen: chloroform). Fractions obtained were tested antioxidant activity, and isolation was done by preparative TLC. The purity of isolated antioxidant compound was confirmed by TLC, and antioxidant potential was measured spectroscopically with DPPH method. This compound displayed antioxidant activity, but its value was lower than that of quercetin used as a positive control (IC50 178.4 v / s 2.17 microg / mL)

Shiitake mushroom (Lentinula edodes (Berk.) Pegler) is one of the fungi that has potentially been used as food and medicinal mushroom. Cultivation in liquid medium by the fermentation process has been developed over recent years. Four isolates of L.edodes (isolates from Malang, Cianjur, Lembang and Yogyakarta) cultured on three types of fermentation media (KM: Medium Kauffman; GYMT: Glucose, Yeast Extract, Malt Extract, Thiamin; YEMR: Yeast extract, Malt Extract, Rice bran). Bioactive metabolites extracted from mycelium biomass and fermentation culture filtrates were tested using pathogenic microbial Staphylococcus aureus ATCC 25923, Escherichia coli ATCC 35218, Candida albicans ATCC 10231, and Trichophyton mentagrophytes. Inhibition zone diameter data were analyzed using analysis of variance followed by Duncan test at 5% error rate. The results showed that bioactive compounds in the culture filtrates and mycelium biomass of L. edodes extracted using chloroform, ethyl acetate and water, were able to inhibit S. aureus, E. coli and C. albicans, but were not able to inhibit T.mentagrophytes. Isolates of L.edodes from Lembang and Yogyakarta cultured on Kauffman Medium gave the best results with inhibitory zones of 24.97 to 31.14 mm. Microbes which gave the most sensitive of bioactive compounds test from L. edodes were C. albicans followed by E. coli, S. aureus and T. mentagrophytes. Bioactive metabolites from L. edodes inhibited potentially pathogenic microbes from the group of bacteria and yeasts but did not inhibit the fungus.

Antioxidant is a substance which in small concentrations can significantly inhibit or prevent the oxidation of the substrate. One plant is efficacious as an antioxidant is the persimmon (Diospyros kakiThunb.) where is cultivated widely in East Asia, Spain and Indonesia. In the search for natural antioxidant compounds, have been studied isolation and identification of antioxidant compound of persimmon leaves (DiospyroskakiThunb.) using DPPH (2,2-diphenyl-1-pikrilhidrazil) method. The extraction of persimmon leaves was carried out by maceration method with wasbenzen. Extracts obtained by evaporating the solvent wasbenzenon a rotary evaporator and were then re-macerated with methanol. Antioxidant activity of extracts was evaluated with DPPH 0.2% method. Active extract was partitioned with chloroform, methanol, distilled water and tested for antioxidant activity by DPPH 0.2% method. The active compound was purified byPTLC and the purified active isolates was then confirmed by TLC. The antioxidant activity (IC50) active isolates were analyzed using spectrophotometry. Analysisof active isolates resulted the antioxidant activity (IC50) of 100.00 ug / ml. UV-Vis spectrum of the active isolates showed absorption at λmax 285 and 401 nm. Infrared spectra (KBR) showed absorption at 3446 cm-1 (OH), 2926 cm-1 (CHaliphatic), 1456 cm-1 (CH2), 1384 cm-1 (CH3), 1255 cm-1, and 1115 cm-1 (C-0-C), 1631 cm-1 (C=Caromatic).
