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

Breast cancer is one of the most common cancer in the world that occurs in women. Thedevelopment process of cancer is regulated by a variety of pathways that involve various enzymes. COX-2 is an enzyme involved in the inflammatory process in further stages that will play importantroles in breast cancer cells progression. The uses of natural compound from plants give new hope forbreast cancer treatment with minimal side effects. Temulawak is a potential breast cancer drugs because it contains curcuminoid and xanthorizol. Curcumin and xanthorizol has been reported to have chemopreventive effect on colon cancer development. The drug that has same functions of these compounds needed to be examined with various approaches. One of the approach used in this research is molecular docking. Based on ligand analysis with Lipinski and toxicity test using ADMET, curcuminoid and xanthorizol met criteria as medicinal compounds. Curcumin had the highest binding affinity(?G) with the value -9.3 kcal/mol but still under commercial drug celecoxib binding affinity (?G) = -12,5. There were three hydrogen bonds in amino acid Arg106 and Tyr341 His75 which were amino acids in the active side of COX-2. There were 15 amino acids that have similar ties with commercial drug celecoxib. Based on the binding affinity and binding similiarity, curcuminoid and xanthorizol were predicted as compounds that have potential as competitive inhibitor of COX-2 enzyme.

Abstract

Dates seeds are one of the byproducts of the date palm juice industry which has the potential for further processing. Dates seeds contain active compounds that are known to have ability to inhibit αglucosidase. This study aims to measure the activity of 70% ethanol extract and the fraction of date palm seeds with a mechanism in inhibiting αglucosidase. The measurement of inhibitory activity was carried out by extracting date palm seeds using 70% water and ethanol. The extraction product is then fractionated with n-hexane, ethyl acetate, n-butanol, and water. Then the total phenolic and flavonoid calculations were calculated for each extract and fraction. Measurement of α-glucosidase inhibition activity was measured based on reaction of substrate to enzyme by the addition of inhibitors. The results showed that the ethanolextract had the highest total phenolic and flavonoid, which were 76.86 mg GAE / g and 21.19 mg QE / g, respectively. n-hexane fraction have the best inhibitory activity seen from the IC50 value, which is 12.69 mg/L. The kinetics of inhibition of 70% ethanol extract of date palm seeds are mixed inhibition. Keywords: α-glucosidase, date seeds, flavonoids, kinetic inhibition, phenolics

Abstract

Banana (Musaceaea) is one of the highest production fruits in Indonesia, which amounted to 7,162,685 tons in 2017. Banana peel waste produced can reach 40% of the total production of fresh bananas. Kepok banana peel contains a lot of nutrients and pectin. Pectin levels in banana peel ranged from 1.92% to 3.25% of dry weight. This study aims to characterize pectin from kepok banana peel (Musa balbisiana) extracted using nitric acid, citric acid, and HCl and screening potential of pectin bioactivity based on LC50 values. The highest pectin yield was obtained from extraction using pH 4 citrate buffer which was 3.68 ± 1.23%. In general, the characteristics of the best pectin from kepok banana peel are pectin extracted with HNO3 pH 4 with methoxyl degree 3.74 ± 0.34%, galacturonate content 87.64 ± 8.36%, and esterification degree 24.24 ± 0.098%. Based on the LC50 value the pectin extraction results can be classified into two, namely commercial pectin and pectin HCl pH 1.5 which is low bioactivity (LC50 > 100 ppm), and pH 4 HNO3 pectin and pH 4 citrate buffer pectin which has high bioactivity (LC50 ≤ 30 ppm). Keywords: Cytotoxicity, galakturonat, kepok banana pectin, methoxyl
