Potensi Antioksidan Rumput Laut Gracilaria verrucosa Dari Pantai Gunung Kidul, Yogyakarta

Abstract: Gracilaria verrucosa is red algae that has been widely used as an antioxidant. This research was conducted to test antioxidant activity, total phenolic content and bioactive compound of Gracilaria verrucosa obtained from Pok Tunggal Beach and Ngandong Beach, Gunung Kidul, Yogyakarta. Research was carried out by descriptive method. Samples were fresh and taken from the beach, then macerated for 3x24 hours in a methanol solvent. Antioxidant test was carried out by electron transfer method with DPPH 0.1 mM and me… Show more

“…Every species has a different compounds which affect its antioxidant activity and depends on extraction method, season, location and the species used in the study [42]. In this research, antioxidant activity of GAE was better than of G. verrucosa from Pok Tunggal water (IC50= 188.53 ppm) [13], while antioxidant activity of ULE was still relatively low compared by U. lactuca extract [43] that have strong antioxidant activity (IC50= 60.975 ppm). The different result occurs because the antioxidant activity are varied, depends on the species of seaweed [44], location [45] and seasons [14], respectively.…”

“…had an IC50 value of 72.9 μg/mL and had total phenolic content of 1.509 ± 0.023 mg GAE/g. Gracilaria species are important for the industrial and biotechnological because they have bioactive compounds such as carotenoid, feofotin, chlorophyll a, chlorophyll b, xantophyll, alkaloid, flavonoid, saponin, fenol, triterpenoid [13].…”

“…The examples of the fatty acids content are caprylic, capric, lauric, myristic, palmitic, stearic, oleic, and linoleic acid (Abast et al ., 2015). The bioactive compounds in seaweed, such as steroids, could also have a role in the total fat content of the soap (Febrianto et al ., 2019). However, the bar soap variants in this study do not yet meet the total fat standard according to the Indonesian National Standard for bar soap, SNI 3532:2016(Badan Standardisasi Nasional, 2016.…”

“…Rumput laut merah yang berpotensi sebagai antioksidan yaitu Galaxaura rugosa (Widowati et al, 2014), Eucheuma spinosum (Podungge et al, 2018), Eucheuma cottoni (Ananda, 2019) , dan Gracilaria sp (Purwaningsih & Deskawati, 2020). Galaxaura rugosa termasuk jenis rumput laut merah (Rhodophyta) (Ruslaini, 2016) yang memiliki senyawa metabolit sekunder yang memiliki kemampuan sebagai antioksidan dan antibakteri (Febrianto et al, 2019). Beberapa penelitian terkait dengan antioksidan dari rumput laut merah Galaxaura rugosa telah dilakukan, seperti yang telah dilakukan oleh Widowati et al, (2014), menentukan aktivitas antioksidan dari Galaxaura rugosa mengggunakan pelarut etil asetat memiliki IC50 sebesar 172,67 ppm.…”

Febrianto et al, (2019) melaporkan bahwa rumput laut merah Galaxaura rugosa dari dua pantai gunung kidul menggunakan pelarut metanol memiliki aktivitas antioksidan yang rendah dengan IC50 sebesar 168,76 ppm dan 188,53 ppm. Mahmudah (2018) menyatakan bahwa hasil uji antioksidan menunjukkan hanya Galaxaura rugosa dari Pantai Newa memiliki potensi sebagai antioksidan.…”
