title: Contribution of phenolics and essential oils to the antioxidant and antimicrobial properties of Disporopsis pernyi (Hua) Diels.
abstract: This study describes the characterization of essential oil and phenolic compounds in Disporopsis pernyi (Hua) Diels. The essential oil was analyzed by gas chromatography-mass spectroscopy (GC-MS) and twelve volatile bioactive compounds of D. pernyi were identified. Polyphenols were identified by reverse-phase high-performance liquid chromatography (RP-HPLC) coupled to electrospray ionization time-of-flight mass spectrometry (ESI-TOF-MS) and quantified by ultrahigh-performance liquid chromatography (UPLC). A total of 4 polyphenolic compounds found in extract were identified as rutin, luteolin, quercetin, and betulinic acid. All obtained extracts and the 4 polyphenolic compounds were evaluated for their antimicrobial and antioxidant properties. The results suggested that the phenolic compounds contributed significantly to the antioxidant and antimicrobial activities of the plant.
