Root specific elicitation and antimicrobial activity of rosmarinic acid in hairy root cultures of Ocimum basilicum
Rosmarinic acid (RA) is a multifunctional caffeic acid ester present in sweet basil (Ocimum basilicum L.). Untransformed normal roots of O. basilicum harbored the maximum titers (0.98% g fresh weight basis) of RA compared to leaves and shoots. Hairy root cultures of O. basilicum transformed with Agrobacterium rhizogenes (ATCC-15834) showed three-fold increases in growth and RA production compar...
متن کاملRapid Separation Method of Ursolic Acid from Pomegranate (Punica granatum L.) Flowers using Normal-Phase Flash Chromatography
Ursolic acid (UA) is a major bioactive component in many traditional medicinal plants including pomegranate (Punica granatum L.) flower. In vitro and in vivo studies have both revealed that UA has many important biological functions.In this study, a rapid and efficient procedure for preparation of UA from an Iranian pomegranate flower cultivar using ultrasound-assisted extraction fo...
متن کاملChicoric acid found in basil (Ocimum basilicum L.) leaves
This is the first report to identify the presence of chicoric acid (cichoric acid; also known as dicaffeoyltartaric acid, which is a caffeic acid derivatizedwith tartaric acid) in basil leaves. Rosmarinic acid, chicoric acid and caftaric acid (in the order of most abundant to least; all derivatives of caffeic acid) were identified in fresh basil leaves. Rosmarinic acid was themain phenolic comp...
متن کاملHepatoprotective triterpenes from hairy root cultures of Ocimum basilicum L.
Six triterpene acids identified as betulinic, oleanolic, ursolic, 3-epimaslinic, alphitolic and euscaphic acids have been isolated from a dichloromethane extract of hairy root cultures of Ocimum basilicum L. (Lamiaceae). These cultures were obtained by genetic transformation using Agrobacterium rhizogenes. The extract as well as the isolated compounds were evaluated for their hepatoprotective a...
متن کاملPreparative isolation of Heteroclitin D from Kadsurae Caulis using normal-phase flash chromatography
Heteroclitin D (H.D) was successfully isolated from Kadsurae Caulis by using flash chromatography and recrystallized by methanol, 10.2 mg of H.D was obtained from 4.86 g of crude extract, and the purity determined by HPLC was 99.4%. The structure was identified by UV, IR, MS, and NMR analysis. The fast, simple and efficient method can be applied to the preparation of reference substance of H. D.
