Abstract
|
Artemisia species belong to Asteraceae family, and have many medicinal properties that
are used to treat a variety of diseases, including: antioxidant, antitumor, antiviral,
antimalarial, antihypertensive, invigorating bloodcirculation, and antiallergy. Artemisia
deserti Krasch is one of the Artemisia species that is a Chinese traditional medicinal herb
[1, 2]. The purpose of this study was to evaluate the phenolic acid compositions of
different extract (n-hexane, chloroform, ethyl acetate, acetone, methanol,
methanol/water, and water) from aerial parts of A. deserti. The extracts were analyzed
by HPLC using C18 column. In this study, a total of 10 phenolic acid components were
identified in the different solvent extracts. The results indicated that the amount of
phenolic acids varied from 0.002 mg/g of plant to 0.778 mg/g of plant in different solvent
extracts of A. deserti herb. Rosmarinic acid and salicylic acid were the dominant
phenolic acid which was detected separately in methanol (0.778 mg/g of the plant) and
methanol/water (0.760 mg/g of a plant) extracts. In different extract, p-hydroxybenzoic
acid was the only phenolic acid identified in all extracts. Cinnamic acid was identified
in all extracts in the amount of lower limit of detection (trace). According to results,
methanol/water extract contain the highest amount of phenolic acids (1.292 mg/g of
plant) followed by methanol extract (1.278 mg/g of plant), and the lowest amount of
phenolic acids was related to n-hexane extract (0.078 mg/g of plant). The results of this
study reveal that the methanol/water extract can be used as functional food ingredients
and/or supplements.
