Abstract

Abstract

The aim of this study was to determine the chemical constituents of volatile constituents from Isatidis Radix, and evaluate the antimicrobial and antioxidant activities using in vitro assays, including disk diffusion test, prussian blue test, ferric reducing antioxidant power and 1, 1-diphenyl-2-trinitrophenylhydrazine free radical (DPPH·) scavenging activity. Results showed that the volatile constituents of Isatidis Radix had low content (0.038%) and comprised of isothiocyanates, aromatic hydrocarbons, carboxylic acids, etc., which were identified by NIST Library. The volatile constituents of Isatidis Radix had antibacterial effects on Escherichia coli and Staphylococcus aureus, and the average antibacterial zone diameters were 8.1 mm and 6.5 mm, respectively. Also, it had good reducing ability, and obvious scavenging effect on DPPH·, with IC₅₀ value of 7.169 mg/mL.
