Abstract

Koja bay leaves (Murraya koenigii) which mostly cultivated in Indonesia and the leaves usually used by Aceh people as a flavoring agent for food, has been known to have an antidiabetic effect.. In this study, we analyzed the antidiabetic effect of koja bay leaves tea bags which commercially available. Methods: The two variant doses of koja bay leaves tea bag (411.11 mg/g body weight and 822.22 mg/g body weight) were administered to 25 male rats which divided into five groups. The antidiabetic activity was determined by measuring blood glucose of rats administered by koja bay leaves tea bag compared to blood glucose of rats in positive control which was given glibenclamide negative control, and normal control. Results: The results showed that dose 1 and 2 decreased blood glucose level by 51.27% and 45.17%, respectively, fairly similar to the glibenclamide (63.38%). Conclusion: Koja bay leaves tea bag have comparable activity with glibenclamide in reducing the blood glucose level.

Abstract

Background: Skin aging is a complex natural process caused by both intrinsic or genetically programmed aging and extrinsic aging caused by environmental factors, such as free radical. The use of antioxidant and anti-collagenase to prevent the aging proses has been known. Natural compounds from plants are one of the sources of antioxidant and anti-collagenase that has ability to prevent aging. Genistein and Epicatechin are the major phenolic compound found in G. max. Objectives: This research was to evaluate the antiaging potential of genistein and epicatechin through antioxidant activity assay (ABTS-reducing activity assay) and collagenase inhibitory activity assay. Methods: Antioxidant analysis of Genistein and Epicatechin was performed by 2,2’- azinobis-3-ethylbenzo-thiazoline-6-sulfonic acid (ABTS) reducing activity Assay. Antiaging assay was conducted through inhibitory of collagenase, one of important enzyme in aging process. Results: ABTS- reducing activity assay showed that both compounds had great ABTS-reducing activity in which epicatechin had better activity than genistein. Epicatechin had low value of IC50 ABTS-reducing activity around 14.39 µg/ml better than genistein with IC50 about 43.17 µg/ml. In terms of collagenase inhibitory activity assay, epicatechin had lower value of IC50 (9.08+-3.46 ug/ml), better than genistein (98.74+-4.25 ug/ml). Conclusion: Epicatechin had higher antioxidant and anti- collagenase activity compared to Genistein.

Abstract

Endothelial dysfunction has been considered as one of the key initial events in the pathogenesis of atherosclerosis and other cardiovascular diseases (CVDs). Several studies imply that chronic inflammation and oxidative stress play a critical role in endothelial dysfunction. The present study was designed to evaluate the preventive effect of alpha-lipoic acid (ALA) on lipopolysaccharide (LPS) induced endothelial dysfunction in rat based on malondialdehyde (MDA) level and vascular cell adhesion molecules-1 (VCAM-1) expression. Thirty Wistar rats were administered ALA for 2 weeks in different doses (30, 60, 120 mg.kg-1 BW) 1 hour before LPS 0.5 mg.kg-1 BW i.p challenge. The LPS was injected on 1st, 4th, and 9th day. MDA plasma level was analyzed with spectrophotometer λ 529 nm, and VCAM-1 expression was determined by immunohistochemistry. Pretreatment with ALA for 14 days could decrease plasma MDA level on LPS-induced endothelial dysfunction in rats. However, only one group of ALA doses, 120 mg.kg-1 BW, showed significant difference with LPS untreated group statistically. It was also found that ALA, in all treatment groups, could attenuate VCAM-1 expression. These findings suggest that ALA had a protective effect against endothelial dysfunction and may potentially prevent vascular inflammatory disease.
