Chemical Composition and Antioxidant Activity of Artemisia argyi Essential Oil and Hydrolate

Abstract

Artemisia argyi, Chinese mugwort, is a plant widely used in China for various purposes from traditional medicine to food. The plant is less known in Europe. From plants grown in Austria, essential oils and their respective hydrolates were obtained, and their compositions were studied. Oxidized monoterpenes 1,8-cineole (32–42%), camphor (12–14%), and borneol (10–12%) were the main components present in both the essential oils and hydrolates. The essential oils also contained 6.6–10.5% monoterpene hydrocarbons such as β-caroyphyllene, camphene, and p-cymene. The hydrolate volatile fractions were devoid of hydrocarbons because of the low solubility of these compounds in water. Neointermedeol (selin-11-en-4-α-ol), a rather rare compound, and caryophyllene oxide were the major oxidized sesquiterpenes in the essential oils and were also present in low levels in the hydrolate volatiles. Furthermore, small amounts of eugenol were in the hydrolate volatiles. The essential oils and hydrolates showed some antioxidant activities in the DPPH and FRAP assays. Essential oils diluted 1:100 corresponded to gallic acid equivalents of 212–274 µg/mL in the FRAP assay and 26.1–30.7 µg/mL in the DPPH assay, while the ranges of activity for the hydrolates corresponded to gallic acid equivalents of 109–597 and 10.5–31.7 µg/mL for FRAP and DPPH assays, respectively.

Current Advances in Antiviral Potential of Artemisia Against Major Viral Infections

“…& Vaniot is a recognized medicinal plant deployed for managing dysmenorrhea, abdominal pain, and inflammation (48). A study identified 69 compounds from A. argyi essential oil (AAEO), with prevalent sesquiterpenes, monoterpenes (1,8-cineole and α-terpineol), and a relatively modest presence of ketones, aldehydes, aromatic, and phenolic compounds (49). Additionally, the study assessed the anti-HBV potential of AAEO, revealing substantial inhibition of HBV DNA replication and HBV antigen secretion (Fig.…”

Preparation and Application of Volatilized Wormwood Essence Derived Naturally into Green Insecticide

“…Wormwood essential oil has a particularly strong odor, with a warm and sometimes bitter herbal aroma [ 30 ]. Wormwood essential oil has complex chemical components, containing over 75 different compounds [ 31 , 32 ]. The main ingredients include anisaldehyde, anisole, anisone, eucalyptus, camphor, and pinene.…”
