Phytochemical, Antibacterial and Antioxidant Activity Evaluation of Rhodiola crenulata

Abstract: The chemical components, as well as the antibacterial and antioxidant activities of the essential oil (EO) and crude extracts prepared from Rhodiola crenulata were investigated. The essential oil was separated by hydrodistillation, and gas chromatography-mass spectrometry (GC-MS) was used to identify its constituents. A total of twenty-seven compounds was identified from the EO, and its major components were 1-octanol (42.217%), geraniol (19.914%), and 6-methyl-5-hepten-2-ol (13.151%). Solvent extraction and f… Show more

“…According to the previously described protocol with some modifications [ 18 , 19 , 20 ], the whole sunflower receptacles were ground into fine powder (1.5 kg) and extracted with the optimal extraction conditions. All filtrates were collected and dried to obtain crude extracts of 186 g. One hundred and fifty of gram of the crude extracts were suspended into water, three solvents (petroleum ether, ethyl acetate, n-butanol) with increasing polarities were successively used to partition plant extracts, the partitioning of each solvent was operated three times, the extract liquor were collected and concentrated by vacuum distillation at 60 °C, 0.8 MPa for 3–4 h. The remaining water was removed by using freeze dryer (Alpha 1-2 LD plus, Christ, Germany) with −52 °C, 0.052 mbar for 72 h. The dry fractions were obtained and recorded as petroleum ether fraction (PEF), ethyl acetate fraction (EAF), n-butanol fraction (nBUF) and water fraction (WAF).…”
