Determination of Antioxidant Compounds, Proximate Compositions and Assessment of Free Radical Scavenging Activities of Nypa Fruticans Wurmb. Sap

Abstract

Nipa palm sap (NPS) as source of medicine traditionally used to treat various diseases. This study identified good radical scavenging activity in NPS with the IC50 value of 33.36 μg/mL using 2, 2-diphenyl-1-picrylhydrazyl (DPPH) assay. NPS comprises of moisture (72.44%), ash (1.04%), protein (7.04%), carbohydrate (19.48%), fat (0%), and energy level (106 kcal). Glucose (0.3%) and fructose (1.8%) were detected using high-performance liquid chromatography. Maleic acid, cinnamic acid, chlorogenic acid, and kaempferol were the predominant compounds revealed by ultra-high-performance liquid chromatography. Overall, NPS has the potential antioxidants sources with significant health benefits and values for commercialisation.

Utilization of Phytochemical Content of Nipah Leaf Extract in the Coastal Area of Indonesia

“…Dalam sistem biologis, senyawa fenolik dan flavonoid berperan sebagai agen penangkap radikal bebas (Lourenço et al, 2019). Menurut Yahaya et al (2021) asam askorbat di nipah menunjukkan aktivitas antioksidan tertinggi dengan nilai IC 50 21,29±0,74 g/mL. Menurut Sowndhararajan dan Kang (2013) semakin rendah IC 50 semakin tinggi aktivitas antioksidannya.…”

Potential metabolites of Arecaceae family for the natural anti-osteoarthritis medicine: A review

“…Several studies related to the nipa palm plant, namely nipa flower stalk extract, have demonstrated its anti-pain and anti-inflammatory activity by suppressing TRPV1 in sciatic nerve injury [ 82 ]. The phytochemical content of the nipa palm plant includes phenolics, alkaloids, tannins, flavonoids, terpenoids, steroids, and saponins [ 83 ]. Nipa palm sap contains phenolics and flavonoids; the fruit skin contains polyphenols and tannins, and the seeds contain alkaloids [ 84 ].…”
