THE COMPARATIVE STUDIES ON PHENYLPROPANOID GLYCOSIDES OF VISCUM ALBUM SUBSPECIES BY HIGH PERFORMANCE LIQUID CHROMATOGRAPHY

Evaluation of the hypoglycemic effect and antioxidant activity of three Viscum album subspecies (European mistletoe) in streptozotocin-diabetic rats

“…Previously, the chemical composition of various V. album subspecies was shown a great variability depending on the host plant (Deliorman et al, 1999). However, only a few studies were conducted on the subspecies/host-specific biologic activity of V. album subspecies (Samuelsson and Jayawardane, 1974;Lorch, 1993;Schaller et al, 1996Schaller et al, , 1998Yeşilada et al, 1998).…”

“…Concerning the quantitative composition, only a few studies were conducted on the particular content of the subspecies; viscotoxins (Schaller et al, 1996), phenylpropanoids (Deliorman et al, 1999) and flavonoids (Lorch, 1993) were comparatively investigated and shown to be exist in different concentrations depending up on the subspecies. Moreover, it was reported that the leaves and twigs of this plant (without discriminating the subspecies) contain ursolic acid, kaempferol, quercetin, pectin, ␤-sitosterol, syringin and lectins as the main components (Ergun and Deliorman, 1995).…”

Phytochemical profile and therapeutic potential ofViscum albumL.

“…austriacum, and in V. album ssp. abietis syringin and coniferin were identified but kalopanaxin D was not detected (Deliorman et al 1999). Their structures are presented in Figure 1.…”

HIGH PERFORMANCE LIQUID CHROMATOGRAPHIC DETERMINATION OF SYRINGIN IN VISCUM ALBUM L. SSP. ALBUM SAMPLES COLLECTED FROM DIFFERENT HOST PLANTS

“…6 The structure of 3034 DELIORMAN AND ERGUN syringin was elucidated by UV, IR, 1 H-NMR, 13 C-NMR, and MS. 7 HPLC grade solvents and bidistilled water were used for the chromatographic studies. album (Armeniaca vulgaris L.) was reported in a previous study.…”

“…4 The literature indicated that, butanol extracts of V. album collected from apple tree, spruce, and elm showed an inhibitory effect on the enzyme, cyclic adenosine monophosphate (cAMP)-phosphodiasterase (PDE). 6 In this study, considering the different host plants, syringin content in nine different V. album ssp. 5 Syringin is the main phenylpropane constituent of V .album (Figure 1), and qualitative and quantitative determinations of this compound in different subspecies were previously reported by using High Performance Liquid Chromatography (HPLC).…”
