Polyphenolic compounds from Platycodon grandiflorum A. DC.

Flavonoids and phenolic acids from the aerial parts of Platycodon grandiflorum A. DC. were analysed by isocratic TLC, MGD-TLC and HPLC methods. Four flavonoid compounds were determined including luteolin 7-O-glucoside as the main component and apigenin 7-O-glucoside, luteolin and apigenin. When performing HPLC analysis, 12 phenolic acids in the free, depside and glycoside forms were identified. Among them, 3,4-dimethoxycinnamic, caffeic, chlorogenic, ferulic, isoferulic, homovanillic, alpha-resorcylic, m-coumaric, p-coumaric, p-hydroxybenzoic, 2-hydroxy-4-methoxybenzoic and 2,3-dihydroxybenzoic acids.

Investigation of the essential oils from three Cephalotaxus species.

Essential oils from leaves of Cephalotaxus fortunei Hook., Cephalotaxus haningtonia K. Koch., Cephalotaxus sinensis Li. and variety Cephalotaxus harringtonia var. drupacea Koidz. underwent qualitative and quantitative analysis. The content of the oils obtained by hydrodistillation in the investigated species was 0.01 - 0.22% v/w. Gas chromatography (GC-MS) with flame ionisation detector (FID) showed generally 47 components in the essential oils. In all investigated species the presence of a-pinene varying from 18.4% to 35.1%, as well as sesquiterpene hydrocarbon beta-caryophyllene up to 22% at Cephalotaxus fortunei were revealed as the main components.
