Search for: [Abstract = "tating \(shoot and suspension\) cultures. The next stage of research involved HPLC determination of the composition and contents of four main lignans of Chinese magnolia vine and eleven phenolic acids, cinnamic and benzoic acid derivatives and the parent compound of one of the subgroups of these compounds \- cinnamic acid. Free phenolic acids \- FPA and total phenolic acids – TPA, free and bound phenolic acids \(obtained after acid hydrolysis\), were estimated. The established shoot\-differentiating callus cultures were characterized by a distinct capability of deoxyschisandrin production. The contents of schisandrin and gomisin A were also high while γ\-schisandrin amounts were lower. The studies demonstrated the effect of plant growth regulators on the lignan production. In addition, it was shown that the cultures at the higher level of differentiation produced many times greater amounts of these compounds than undifferentiating callus cultures. The maximum contents of lignans equaling 308.51 mg\/100 g d.w. for deoxyschisandrin, 86.41 mg\/100 g d.w. for gomisin A, 75.54 mg\/100 g d.w. for schisandrin and 22.09 mg\/100 g d.w. for γ\-\-schisandrin, were obtained in agar shoot\-differentiating callus. The maximum contents of these compounds in undifferentiating callus cultures amounted to 18.75 mg\/100 g d.w., 2.66 mg\/100 g d.w., 2.16 mg\/100 g d.w. and 1.03 mg\/100 g d.w., respectively."]
