Abstract

Peperomia pellucida L. Kunth known as “Katumpangan Air” is a potential medicinal plants used traditionally for uric acid, rheumatic, headache, stomachache, antimicrobial. This study aims to establish  the non-specific  and specific parameters of ethanol extract from Katumpangan air (EKA). EKA was collected from three different growth places: South Tangerang (6.833%), Bogor (7.8%) and Yogyakarta (13.125%). The results show that organoleptic extract characterization from three places were same: thick, blackish green brown, bitter and have a characteristic odor. The average content of water-soluble compounds was within range 7.39-13.29%, ethanol-soluble 15.33-16.68%, flavonoid total 3.807-4.244%. The range of moisture content was 12.25-16.34%, ash total 1.21-2.78%, acid insoluble ash 0.19-1.62%, drying shrinkage 21.62-24.98%, specific gravity 1.0010-1.0034 g/mL for the non-specific parameter. Microbial contamination testing results 0.61x103-1.13x103 coloni/g, the contaminant testing mold/yeast 0.1x102-1.7x102 coloni/g, while lead metal 0.15-0.18 mg/kg, cadmium 0-0.11 mg/kg and arsenic <0.005µg/kg.

Abstract

The flavone glycoside was isolated from ethyl acetate fraction of ethanol extract of leaves Pterocarpus indicus Willd. The isolation was conducted by gravitation column chromatography and eluted successively with hexane, ethyl acetate and methanol by gradient, and purified by sephadex-LH20. The structure was elucidated base on spectroscopy data of NMR (1D and 2D), UV, LC-MS and FT-IR. Antioxidant was evaluated using 2,2-diphenyl-1-picrylhidrazyl (DPPH) radical scavenging. The isolation and identification led a stigmasterol as Compound 1 and a new flavonol-glycoside [(2R)-7-hydroxy-3-(3,4,5-trihydroxy-6-(hydroxymethyl)tetrahydro-2H-pyran-2-yloxy)-2-(3,4,5-trihydroxy phe nyl)chroman-4-one] or ptevon-3-D- glycoside as Compound 2. Antioxidant activity of Compound 2 showed IC50 for 18.53 mmol and blank of quercetin was 7.94 mmol and Vitamin C was 40.25 mmol. These compounds and antioxidant activities are the first time reported from this plant.

Abstract

Dengue hemorrhagic fever (DHF) is major public health problem in tropical and subtropical areas of the world with lack of approved vaccines and effective antiviral therapies. With no current treatment for illness attributed to dengue virus (DENV) infection other than supportive care, therapeutic strategies that use natural extract was developed. Indonesia have many plants that potential for antiviral drµgs such as Pterocarpus indicus Willd (P. indicus). The objective of this study was to determine the effect of P. indicus to inhibit DENV replication. We used a well-differentiated hepatocytes-derived cellular carcinoma cell line (Huh-7 it-1 cells) to determine and select antiviral activity. The toxicity effects were determined by MTT assay. Then, the suppression of DENV replication was determined by Focus assay. Dengue infected cells with DMSO were used as control. We found that crude extract (Pi), hexane (Pi.1) and ethyl acetate (Pi.2) extract showed strong inhibition with high selectivity index (SI) of 1,392; 285.36 and 168.56 respectively.  Sub fraction of Pi.1 and Pi.2 still showed strong inhibition with high SI.  Further sub-sub fraction of Pi.2 such as Pi.2.12 and Pi.2.12.1 still showed inhibition of DENV replication but there was reduction of SI value. The mechanism experiment of Pi.2.12, we found that Pi 2.12 more profound to inhibit in the post infection stage that entry or pre-infection. We conclude that the sub-fraction of Pi.2.12 has potential antiviral activity against DV infection in vitro. Further studies are still needed to investigate the pure compound of Pi.2.12 that inhibit and have advantages in the future as alternative for treatment of DENV infection.

Abstract

      Peperomia pellucida was used traditionally in Indonesia for health treatment: wounds, boils, pimples, abscesses, abdominal pain, colic, gout, kidney, rheumatic pain, fatigue headache, furuncles, conjunctivitis and anti dermatogenic and also for dengue treatment. The isolation compounds from hexane and ethyl acetate fractions of Peperomia pellucida L. are  conducted by maceration of the dry herbs sample with methanol and partition with hexane, ethyl acetate, butanol and water.The hexane and ethyl acetate fractions were fractionated by gravitation column chromatography and eluted successively with hexane, ethyl acetate and methanol by the gradient. The structure was elucidated base on spectroscopy data of NMR proton and carbon for one and two dimension, LC-MS and FT-IR. The isolation founded three compounds are stigmasterol, analogue of pheophytin and b-sitosterol-D-glucopyranoside.

Abstract

Background: Increased lipase activity can increase the amount of monoglycerides and fatty acids absorbed by the body, this is what affects obesity. If pancreatic lipase activity is inhibited, the production of fatty acids will decrease, consequently the level of fat in the blood will also decrease.Objective: To study anti obesity potential of a single herb or a mixture of green tea and other herbs (Syzygium polyanthum. Lv, Artocarpus communis.Lv, Cinnamomum verum..Lv, Manilkara zapota.Lv, Tectona grandis.Lv) by the in vitro inhibition assay of the lipase enzyme activityMethod: A single (8 herbs) or a mixture of three herbs powder (12 formulas) was put into a tea bag with a total weight of 1.5 g to be brewed in 100 mL bottled mineral water at 70⁰-90⁰C for 10 minutes. In vitro lipase enzyme inhibition assay were conducted to measure the ability of these samples as lipase inhibitor. Orlistat used as positive lipase inhibitor. Results: There was a difference results of lipase inhibition activity between the sample of a single and a mixture of herbs. Interestingly, the results shows that formula 3 (mixture of green tea, Manilkara zapota and cinnamon). has 53.942 % inhibition, formula 9 (a mixture of green tea, Syzygium polyanthum and cinnamon) has 67.322 % inhibition and formula 12 (a mixture of green tea, Tectona grandis and cinnamon) has 56.612 % inhibition which close to lipase inhibitory activity by standard Orlistat.Conclusion: The mixture of green tea and two other herbs has a lipase inhibitory activity similar to Orlistat, when compared to the single herb. The highest lipase inhibitory activity is found in formula 9.
