Bioanalytical HPLC method of Piper betle L. for quantifying phenolic compound, water-soluble vitamin, and essential oil in five different solvent extracts

2019 Journal of Applied Pharmaceutical Science  
A reversed-phase high-performance liquid chromatography with diode-array detection (HPLC-DAD) was developed and validated to estimate the phenolic acids (gallic acid, caffeic acid, syringic acid, p-coumaric acid, sinapic acid, and ferrulic acid), flavonoids (catechin rutin, myricetin, quercetin, apigenin, and kaempferol), ascorbic acid, and eugenol. The chromatogram condition was set in suitable wavelength 272 nm and run flow rate 0.7 µl/minutes using HPLC Agilent Technologies 1260 Infinity, a

The linearity, precision, limit of detection, limit of detection, and accuracy were R 2 > 0.9907, relative standard deviation < 1%, 0.005 µg/ml, 0.015 µg/ ml, and 96%-102%, respectively. As a result, all the selective compounds were successfully separated, identified, and quantified. The enormous contents were found in quercetin and eugenol, expressing crude content (mean, 5.989 mg/g) and residue content (mean, 1.934 mg/g) for quercetin, while crude content (mean, 3.209 mg/g) and residue content (mean, 0.184 mg/g) for eugenol. Consequently, this method could be applied, repeated, and developed for the later observation, especially in commercially inclination of Piper betle analysis.
