Abstract

Skin aging processes are divided into chronological aging and premature aging. Premature aging is generally caused by free radicals, from both air pollution and photoaging. Natural compounds from plant extracts are among sources of antioxidants and anti-hyaluronidase which have the ability to prevent antiaging. One of the potential fruits related to antioxidant and antiaging activities is Anana scomosus. A. comosus has a number of phenolic compounds with biological activities. One of the main phenolic compounds in A. comosus is luteolin. The aim of this study was to evaluate the antioxidant and antiaging potentials of Pineapple Core Extract (PCE). This study was conducted at the Biomolecular and Biomedicine Research Center, Aretha Medika Utama from August to November 2018. Analysis of antioxidants from PCE and luteolin was carried out using H2O2 scavenging activity assay. The antiaging assay was carried out through inhibition of hyaluronidase enzyme, one of the important enzymes in the aging process. Luteolin had lower IC50 value of H2O2 scavenging activity of around 24.12±3.13 μg/ml, which was better than CPE with IC50 of 304.56±3.76μg/mL. The results of hyaluronidase inhibition activity assay showed that luteolin compound had a lower IC50 value of 67.38±3.99 μg/mL when compared to PCE with an IC50 value of 161.15±1.05 μg/mL. Hence, Luteolin has higher antioxidant and anti-hyaluronidase activities than PCEPerbandingan Aktivitas Antioksidan dan Antihialuronidase Ekstrak Bonggol Buah Nanas (EBN) dengan Senyawa LuteolinTerdapat dua jenis proses penuaan kulit, penuaan kronologis dan penuaan dini. Penuaan dini umumnya disebabkan oleh radikal bebas, baik dari polusi udara maupun photoaging. Penggunaan antioksidan dan antihialuronidase untuk mencegah proses penuaan telah banyak diketahui. Ananascomosus merupakan salah satu tanaman yang memiliki potensi sebagai antipenuaan dan antioksidan karena mengandung sejumlah senyawa fenolik yang memiliki berbagai aktivitas biologis. Salah satu senyawa fenolik utama dalam A. comosus adalah luteolin. Tujuan penelitian ini adalah untuk mengevaluasi potensi antioksidan dan anti-aging dari Ekstrak Bonggol Nanas (EBN) dan senyawa pembandingnya yaitu luteolin . Penelitian ini dilakukan di Biomolecular and Biomedicine Research Center, Aretha Medika Utama dari Agustus hingga November 2018. Pengujian antioksidan dari EBN dan luteolin  dilakukan menggunakan uji pemerangkapan H2O2. Uji antipenuaan dilakukan melalui uji penghambatan aktivitas hialuronidase, salah satu enzim penting dalam proses penuaan. Hasil penelitian menunjukkan bahwa Luteolin  memiliki nilai IC50 aktivitas pemerangkapan H2O2lebih rendah sekitar 24.12±3.13 μg/ml lebih baik daripada EBN dengan IC50 sebesar 304.56±3.76μg/mL. Hasil uji aktivitas penghambatan hialuronidase, senyawa luteolin  memiliki nilai IC50 lebih rendah, yaitu sebesar 67,38±3,99 μg/mL dibanding dengan EBN nilai IC50 161,15±1,05μg/mL. Hasil ini menunjukkan bahwa senyawa pembanding luteolin  memiliki aktivitas antioksidan dan antihialuronidase yang lebih tinggi daripada EBN.

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.
