Abstract

Pomegranate has valuable nutritional content and contains various bioactive compounds, one found in the fruit's peel. The utilization of these bioactive compounds could be used as herbal medicines and supplements, such as antioxidants. This study aimed to determine the antioxidant capacity, phytochemical profile, and pomegranate peel extract grouping using different extracting solvents. The three extracting solvents used were water, 70% ethanol, and ethanol p.a. Antioxidant capacity of the three extracts was measured using the DPPH and CUPRAC methods. We also determined the total phenolic and flavonoid levels and the TLC fingerprint analysis and FTIR spectrum of the pomegranate peel extracts. The 70% ethanol extract owned the largest antioxidant capacity than the other two extracts with a value of 358.67 and 2981.59 µmol trolox/g dried sample using the DPPH and CUPRAC methods, respectively. The three pomegranate peel extracts' total phenolic and flavonoid levels ranged from 287.26–1068.81 mg GAE/g dried sample and 0.24-0.75 mg QE/g dried sample. TLC fingerprint analysis of pomegranate peel extract yielded 2, 6, and 6 bands for water extract, 70% ethanol, and p.a ethanol, respectively. The three extracts can be grouped based on FTIR spectrum data using principal component analysis using three principal components with a total variance of 93%. The results obtained show that using different extracting solvents provides different antioxidant capacities and phytochemical profiles.

Abstract

Tumbuhan Asteraceae dilaporkan mengandung metabolit sekunder tinggi yang aktif sebagai antioksidan. Senyawa antioksidan juga digunakan untuk mencegah penuaan/reaksi glikasi. Penelitian ini bertujuan menentukan aktivitas antioksidan dan antiglikasi 7 tumbuhan Asteraceae. Daun Adenostema lavenia, Ageratum conyzoides, Dichrocephala integrifolia, Galinsoga parvifolia, Synedrella nodiflora, Mikania micrantha, dan Sphagneticola trilobata masing-masing diekstraksi menggunakan air. Ekstrak kemudian ditentukan kandungan total fenol, flavonoid, dan aktivitas antioksidan menggunakan metode 1,1-difenil-2-pikrilhidrazil (DPPH) dan 2,2’-azino-bis(3 ethylbenzothiazoline-6-sulfonic acid (ABTS), serta aktivitas antiglikasi. Ekstrak dengan kadar total fenolik dan flavonoid tertinggi adalah ekstrak M. micrantha. Ekstrak A. lavenia memiliki aktivitas antioksidan terhadap DPPH tertinggi dengan nilai IC50 sebesar 121,82 μg/mL dan A. conyzoides tertinggi terhadap ABTS dengan kapasitas sebesar 4,51 mg trolox ekivalen (TE)/g ekstrak. Aktivitas antiglikasi tertinggi pada ekstrak G. parvifolia sebesar 90,67% yang tidak berbeda nyata dengan ekstrak A. lavenia (87,87%) dan S. trilobata (87,38%). Secara keseluruhan ekstrak A. lavenia dan S. trilobata baik dikembangkan sebagai antioksidan dan antiglikasi.

Abstract

It has been reported that the lidah mertua plant (Sansevieria trifasciata) can absorb electromagnetic radiation from vari-ous electronic equipment. The current study aimed to make a film layer from polyvinyl alcohol (PVA) and a dichloro-methane (DCM) fraction of S. trifasciatato reduce heat radiation from smartphones. S. trifasciataleaves were macer-ated using ethanol and partitioned with ethyl acetate, DCM, and n-butanol. The DCM fraction was chosen to create the film, for which PVA was also used. The blended film made from PVA and 0.02% DCM reduced heat radiation from smartphones by up to 4.4 °C starting from the first minute of use; its heat reduction remained stable until the 20th mi-nute. Based on these results, it was determined that the active compounds in the DCM fraction are closely related to saponin-type steroids.
