Component Analysis and Antioxidant Activity of Oenanthe javanica Extracts

Abstract

The purpose of this study was to determine the possibility of using Oenanthe javanica as a natural health food source. To accomplish this, its general and biological activities were measured. Its carbohydrate, crude protein, crude lipid, and ash contents were 44.7, 9.8, 8.9, and 27.8%, respectively. The K content was largest for minerals followed by Ca, P, and Mg, which means that Oenanthe javanica is an alkali material. The concentrations of total phenol and flavonoids of OJE were 88.9±0.46 mg GAE/g, and 28.6±0.64 mg QE/g, respectively. Gallic acid, catechin, chlorogenic acid, and caffeic acid in OJE as measured by using HPLC were 0.9±0.23, 1.2±0.19, 227.1±0.62, and 4.0±0.35 mg/g. The DPPH and ABTS radical scavenging activities of OJE were 72.2%, and 66.1%, respectively, at 1,000 µg/mL. The FRAP and reducing power of OJE were 0.79, and 0.41 absorbance units value respectively, at 1,000 µg/mL. OJE possessed significant antioxidant properties, which suggests its great potential as a functional ingredient for food applications.

Ulam Herbs of <I>Oenanthe javanica</I> and <I>Cosmos caudatus</I>: an overview on their Medicinal Properties

“…Persicarin and isorhamnetin are the main components isolated from the methanol extract [8][9][10] . Analysed using HPLC, chlorogenic acid (227 mg/g) is the dominant phenolic compound in the ethanol extract of O. javanica 11 . The hydrophilic extract contains chlorogenic acid, quercetin rhamnosyl galactoside, rutin, hyperoside and isoquercitrin, while lutein, γ-tocopherol and α-tocopherol have been identified in the lipophilic extract 12 .…”

A Review ofOenanthe javanica(Blume) DC. as Traditional Medicinal Plant and Its Therapeutic Potential

“…Phenolics are also abundant in O. javanica , including neochlorogenic acid [4], chlorogenic acid [4, 5, 11, 60], caffeic acid [4, 5, 48, 57, 60], gallic acid [4, 57], α -tocopherol [10, 61], lunularin, p -hydroxyphenylethanol ferulate, 5- p -trans-coumaroylquinic acid [18], carvacrol, ferullic acid [57], and catechin [45] (the structures are presented in Figure 3). For phenolic acids and ester identified from O .…”

“…javanica , most of them are caffeic acid derivatives. The content of total phenolic acids in O. javanica from Korean was 88.9 ± 0.46 mg GAE/g [45] and in O. javanica from Guizhou Province of China was 131.5-173.2 mg/g [62]. In addition, O. javanica extract contains α -tocopherol (146.8 mg/kg) [61], gallic acid (0.9 ± 0.23 mg/g), catechin (1.2 ± 0.19 mg/g), chlorogenic acid (227.1 ± 0.62 mg/g), and caffeic acid (4.0 ± 0.35 mg/g) [45].…”

“…The fresh O. javanica plant has wide variety nutrients such as carbohydrates, proteins, vitamins, and fat, as well as mineral micronutrients, as shown in Table 4 [10, 45–47]. O .…”

“…javanica has high iron content, followed by kalium, calcium, natrium, and magnesium, which are useful for patients with mineral deficiencies problems. The plant has moisture content of up to 88% [10] and a total ashes value of 8.9% [45] suitable for body hydration.…”
