SummaryThe extraction, fractionation, and chromatographic separation of a series of proanthocyanidin monomers and oligomers were facilitated using a flavonoid-rich cell culture of Vaccinium pahalae Skottsberg as the donor tissue. The cell cultures, after exposure to light, readily accumulated anthocyanin pigments and other flavonoids in relatively large amounts, with minimal concurrent production of pectins, enzymes, and complex sugars produced in field-grown Vaccinium berries. The absence of… Expand

Biosynthesis and characterization of 14C-enriched flavonoid fractions from plant cell suspension cultures.
A range of radiolabeled anthocyanins, proanthocyanidins, and other flavonoids were accumulated by cell suspension cultures of two plant species, ohelo and grape, after providing uniformly labeled sucrose to the medium to gauge their bioavailability and accumulation in target organs. Expand
Composition of a chemopreventive proanthocyanidin-rich fraction from cranberry fruits responsible for the inhibition of 12-O-tetradecanoyl phorbol-13-acetate (TPA)-induced ornithine decarboxylase (ODC) activity.
Antioxidant activity was not restricted to a particular class of components in the extract but was found in a wide range of the fractions, and significant chemopreventive activity was localized in one particular proanthocyanidin-rich fraction from the initial fractionation procedure. Expand
Sorting out bioactivity in flavonoid mixtures.
A plant-cell-culture production approach that provides uniform yields of abundant natural mixtures of flavonoids from small molecules to high molecular weight oligomers and polymers is described. Expand

Polyphenolics in Rhizophora mangle L. leaves and their changes during leaf development and senescence
The overall pools of plant phenolics in R. mangle leaves are quantified, identify the major constituents of these pools and document their changes during leaf maturation and senescence, where polyphenolic pools become simplified. Expand
Proanthocyanidin biosynthesis--still more questions than answers?
This work reviews the structures of proanthocyanidins reported over the past 12 years in the context of biosynthesis, and summarizes the outstanding questions concerning synthesis from the chemical, biochemical and molecular genetic perspectives. Expand


Procyanidins (Condensed Tannins) in Green Cell Suspension Cultures of Douglas Fir Compared with Those in Strawberry and Avocado Leaves by Means of C(18)-Reversed-phase Chromatography.
Douglas fir preparations contained the most complex set of procyanidins and consisted of oligomers of catechin and epicatechin, whereas strawberry and avocado contained mainly (+)-cate chin and (-)-epicatechin derivatives, respectively. Expand
Isolation of bioactive constituents from Vaccinium myrtillus (bilberry) fruits and cell cultures
The concentration of the extract required to double QR specific activity was 9 μg/150 μl per well, which indicates that one or more components possess substantial QR-inducing capacity, comparable to known QR inducers such as furanone and catechol. Expand
