Protea caffra is used as a diarrhoeal remedy in South African herbal medicine, however, its\npharmacological properties remain largely unknown. In the present study, extracts from different\nProtea caffra organs were screened against drug-sensitive and -resistant diarrhoeagenic pathogens\nusing the microdilution assay (minimum inhibitory concentration, MIC). Twig extracts (70% methanol,\nMeOH) of the plant were purified and the resultant fractions screened for antibacterial properties\n(MIC). The chemical profiles of the fractions were determined by Gas Chromatography-Mass\nSpectrometry (GC-MS), while ultra-high-performance liquid chromatography-tandem mass\nspectrometry (UHPLC-MS/MS) was used to quantify the phenolic acids in the plant. The mutagenic\nproperties of bioactive extracts were assessed using the Ames test..........................
Helichrysum petiolare (Asteraceae family) is part of the Helichrysum genus which comprises\nof an estimated 600 species. Several parts of the plant have been used traditionally for the treatment\nof various ailments, such as cough, infection, asthma, chest problems, diabetes and wounds. Given its\nvarious chemical constituents with anticancer properties, there has been no scientific evidence of its\nusage for the treatment of cancer. This study aims to investigate the anti-proliferative and genotoxic\nactivities of H. petiolare methanol extract........................
Pistacia lentiscus L. is a Mediterranean shrub known for its health promoting effects\nattributed to a large extent to polyphenols accumulated in all parts of the plant. Microwave-assisted\nextraction is a green extraction technique enabling fast and effective isolation of plant polyphenols.\nTherefore, the aim of this research was to optimize the microwave-assisted extraction of polyphenols\nfrom Pistacia lentiscus L. leaves and fruit in terms of temperature, extraction time and microwave\npower and to evaluate their............................
Hibiscus schizopetalus (Dyer) Hook.f. (Malvaceae) is an ornamental plant. The aim\nwas to investigate its antimicrobial and antioxidant activities. In vitro antiviral, antibacterial,\nand antioxidant activities of the 70% ethanolic extract (Et-E) of the aerial parts of the plant\nwere determined. The Dichloromethane Fraction (DCM-F) and the n-Butanol Fraction (Bu-F) were\nassessed using Liquid...............................
Rosa banksiae Ait. (R. banksiae) is a traditional Chinese folk medicine and an ornamental\nplant. Most previous studies have focused on cultivation and utilization while there are few research\npapers on the pharmacological activity of R. banksiae. This study aimed to get a better understanding\nof R. banksiae by extracting polyphenols with fractionated extraction technology. The results showed\nthat ethyl acetate phase (EAP) contained the most polyphenols................................
