Decorative Magnolia Plants: A Comparison of the Content of Their Biologically Active Components Showing Antimicrobial Effects

Popis výsledku v původním jazyce

Magnoliaplants are used both as food supplements and as cosmetic and medicinal products. The objectives of this work consisted of preparing extracts from leaves and flowers of eight Magnoliaplants, and of determining concentrations of magnolol (1 to 100 mg.g(-1)), honokiol (0.11 to 250 mg.g(-1)), and obovatol (0.09 to 650 mg.g(-1)), typical neolignans for the genusMagnolia, in extracts made by using a methanol/water (80/20) mixture. The testedMagnoliaplants, over sixty years old, were obtained from Pruhonicky Park (Prague area, Czech Republic):M. tripetala MTR 1531,M. obovataMOB 1511, and six hybrid plantsMagnolia x pruhoniciana, results of a crossbreeding ofM. tripetalaMTR 1531 withM. obovataMOB 1511. The identification of neolignans was performed by HRMS after a reversed-phase high-performance liquid chromatography (RP-HPLC) fractionation of an extract fromM. tripetalaMTR 1531. The highest concentrations of neolignans were found in the flowers, most often in their reproductive parts, and obovatol was the most abundant in every tested plant. The highest concentrations of neolignans were detected in parent plants, and lower concentrations in hybrid magnolias. Flower extracts from the parent plants M. tripetala MTR 1531 and M. obovata MOB 1511, flower extracts from the hybrid plants Magnolia x pruhoniciana MPR 0271, MPR 0151, and MPR 1531, and leaf extract from the hybrid plant Magnolia x pruhoniciana MPR 0271 inhibited growth ofStaphylococcus aureus.
