ANALISIS KANDUNGAN VITAMIN C DAN β- KAROTEN DALAM DAUN KELOR (Moringa oleifra Lam.) DENGAN METODE SPEKTROFOTOMETRI UV–VIS

Abstract

This research aimed to analyze the levels of vitamin C and β-carotene in Moringa leaves extract (Moringa oleifera Lam.) using UV-Vis spectrophotometry. Vitamin C on Moringa leaves are extracted with ethanol 96%. The extracts obtained was qualitatively analyzed of levels of vitamin C using specific reagents an iodine 1% and ammonium molybdate 5%. Than quantitatively using UV-Vis spectrophotometry at wavelength of 570 nm, obtained an verage grade of 7,96 mg/g. For β-carotene, Moringa leaves were extracted with acetone. The extract obtained was extracted again with ether, then saponified with KHO solvent 15% w/v in methanol, allowed to stand overnight. The extract obtained was extracted again with ether, then freed from wet with distilled water. Extracts were analyzed qualitatively using thin layer chromatography and quantitatively using UV-Vis spectrophotometry at wavelength of 450 nm and obtained an average grade of 3,31 mg/g.

The Characteristics of Probiotic Drink Based on Moringa Leaves Juice

“…According to Werdhasari (2014), antioxidants from natural ingredients are obtained from active ingredients such as vitamin C, vitamin E, provitamin A, organosulfur, and flavonoids. The most nutritious moringa plant content is the antioxidants, especially in the leaves that contain high antioxidants such as i a i E α-tocopherol) 104 mg/100 g (Mubarak et al, 2017) vitamin C 203.1 mg.100 g-1 DM (Lalas et al, 2017), and vitamin A around 3.31 mg/g (Tahir et al, 2016). The difference in antioxidant activity and total phenol content is due to antioxidant compounds, including polyphenols found in moringa leaves.…”

“…In patients with iron deficiency anemia in general the treatment often given is iron supplements, and is valued by consuming iron-rich foods [10]. Foods that contain lots of iron from animal foods such as meat, fish, while plant foods that contain lots of iron are dark green vegetables, nuts [11]. One of the plants and herbal ingredients that contain iron and can be used as an alternative to overcome the problem of iron deficiency anemia, namely Moringa leaves and honey [12].…”

PENGARUH PENAMBAHAN TEPUNG DAUN KELOR (Moringa oleifera Lamk) TERHADAP KADAR β-KAROTEN DAN ORGANOLEPTIK BAKSO IKAN PATIN (Pangasius pangasius)

“…β-karoten adalah bentuk provitamin A yang paling aktif. Karotenoid termasuk juga β-karoten memiliki sifat fungsional sebagai antioksidan, mencegah penyakit rabun senja, penyakit kanker terutama kanker paru-paru [9]. Selain itu β-karoten yang merupakan provitamin A memiliki fungsi fisiologis pada tubuh seperti fungsi penglihatan, diferensiasi sel, imunitas tubuh, pertumbuhan dan perkembangan serta reproduksi [10].…”
