Abstract

Temulawak or Curcuma xanthorrhiza Roxb, is usually used as traditional medicine (herbal medicine) that has antioxidant, anticancer, antihyperglycemic, anti-inflammatory, hepatoprotective and gastroprotective properties. The main components contained in temulawak responsible for its efficacy as a medicine are xantorhizol and curcuminoid. Curcuminoid has drawbacks, which are difficult to absorb and very quickly metabolized by the body, so that limit its bioavailability. The use of solid lipid nanoparticle carrier system (SLN) in form of palmitic acid, is known to improve the bioavailability of curcuminoid. This study aims to find the effective dose of nanocurcuminoid coated with palmitic acid that can be used as an anti-inflammatory agent. The methods used in this study, include the production of nanocurcuminoid with homogenization and ultrasonication methods, determination of particle size, polydispersity index, entrapment efficiency and anti-inflammatory activity test through rat feet edema. Nanocurcuminoid obtained in this study was 561.53 nm in size, with polydispersity index 0.309 and concentrations of curcuminoid absorbed and entrapment efficiency were 0.61±0.031 mg/mL, 58.93±3.021%, respectively. Anti-inflammatory activity of nanocurcuminoid through treated Sprague Dawley rats, showed that there were no significant difference compared with the positive control, curcuminoid extracts and empty nanoparticle. These results indicate that nanocurcuminoid with 175, 200 and 250 mg/kg.bw in doses, has greater anti-inflammatory activity (31.70%) compared to the other treatments.

Abstract

Study on the chemical compound of painted nettle (Coleus blumei Benth) leave extract and its anthelmintic activity against chicken tapeworm were conducted. Leave of painted nettle were collected and extracted with hexane, chloroform, ethanol and water. Phytochemical analysis was carried out to determine the chemical compound of secondary metabolites. Anthelmintic activity was evaluated with an assay using chicken tapeworm in a serial microplate dilution method by determination of efective concentration 50 (EC50) using probit analysis. The result of phytochemistry analysis showed that Coleus leaves consisted of flavonoid, steroid, tannin and saponin. Three of four extracts displayed strong anthelmintic activity with the higest activity belong to chloroform extract with EC50 5 mg/ml followed by n-hexane 9 mg/ml and metanol extract 10,2 mg/ml, while water extract has a weak anthelmintic activity with 106,2 mg/ml. In general, chloroform extract proved to be a more efficient extractant of biologically active compounds than either hexane, ethanol or water extract. The promising activity displayed by a number of extracts has led to further investigation of the active compound. Unfortunately, the result of invivo assay showed that the chloroform extract treatment with dose level 25 mg/kg BW could not to reduce the number of tapeworm in chicken. It is interesting for further investigate the differences of respon between in vitro and in vivo to determine involved factors.

Abstract

A laboratory scale research to obtain environmentally safe effluent and liquid fertilizer from leachate from Final Waste Disposal Site in Galuga owned by Regional Government of Bogor City was conducted from July 2006 through to April 2007. The experiment was initiated by aerating the leachate in 4 difference aeration rates (0, 10, 30 and 70 liters/minute) followed by processing the sediment to product the liquid fertilizer. The experiment of production liquid fertilizer was carried out by adding lime with different dosage into sediment generated from processing by aerating at 70 liters/minute followed by centrifugation process or secher. Further, the liquid fertilizer generated from such experiment was applied to chilis planting (Capsicum annum). The research found that the processing conducted by aerating at the rate 70 liters/minute was the most effective in reducing pollutant from leachate. The addition of 1000 ppm CaO or Ca(OH)2 limes in sediment from aeration is the most effective in depositing the dissolved material compared to the addition of limes in other dosage. Liquid fertilizer generated through the addition of 1000 ppm CaO have the content of N = 375,83 ppm, P = 121,44 ppm, K = 948,11 ppm, Ca = 827,20 ppm, Mg = 959,50 ppm, S = 48,53 ppm, Cu = 8,23 ppm, Zn = 30,02 ppm, Mn = 230,57 ppm, Fe = 320,95 ppm, Pb = 10,34 ppm, Cd = 7,46 ppm and Cr = 2,05 ppm. The use of liquid fertilizer generated by adding 1000 ppm CaO was the most effective in enhancing vegetation growth and production of chili. The non essential elements (Pb, Cd and Cr) in fruits from vegetation given liquid fertilizer produced from such treatment did not exceed tolerable threshold.

Abstract

Tabat Barito (Ficus deltoidea) is known as a plant that has potency as an antioxidant because of containing a significant phenolic compound. In this study, we performed metabolite profiling on F. deltoidea leaves by UPLC-QTOF-MS/MS to identify its phenolic compounds. Extraction by maceration and ultrasonication techniques with methanol (MM and UM) and ethanol (ME and UE) were used to extract the F. deltoidea metabolites. About 70 metabolites were identified by using UPLC-QTOF-MS/MS in negative ion mode. The amounts of metabolites found in each extract were different, i.e., 45 metabolites in MM, 64 metabolites in UM, 42 metabolites in UE and 41 metabolites in ME. MS/MS could further tentatively identify 16 metabolites. The identified compounds belonged to the class of flavonoids and phenolic acid. Also, we conducted an antioxidant activity by using DPPH method on each extract to determine its potency as an antioxidant. The highest antioxidant activity was exhibited by UM extract (IC50 71.93 ppm) may be due to the number of metabolites in UM extract which was higher than the other extract based on the detected metabolites.
