The inclusion of the Cunoniaceae within a rosalean alliance is unquestioned, but its position in such an alliance is uncertain. In respect of proanthocyanidins, flavonols, ellagitannins and absence of iridoids the most closely similar taxa are Saxifr

Leaves of a further 25 species of Acer, mostly from Asia and N. America, show similar levels of astringency and distribution of condensed and hydrolysable tannins to those previously examined. The results are tabulated and discussed in accordance wit

Procyanidin A from Aesculus hippocastanum differs from the B type procyanidin in that it is difficultly soluble in water, gives a higher yield of cyanidin when heated in butanolic HCl and the production of cyanidin continues beyond the 2 hr period su

Fifty per cent methanolic extracts of the leaves of 70 species (including some subspecies, varieties and one hybrid) of Geratiium have been analysed for proanthoeyanidins, total galloyl esters, hexahydroxydiphenoylglucose and astringency. Proanthoeya

The tannins of the leaves of Viburnum and Hydrangea species consist of proanthocyanidins only, but in each genus the range is very wide. In several species of Hydrangea the proanthocyanidins are of the A type, otherwise they are mostly tri- or tetram

All 25 species of Acer examined contain condensed (proanthocyanidins) and hydrolysable (gallo- and/or ellagi-) tannins, but each of these varies ov

The association of particular constituents with particular groups of plants, and attempts made to fit them into systems of classification are reviewed. Muller's data on the earliest plant records are used to estimate the time of appearance of differe

The tannins of the leaves of five of the relatively few species of herbaceous Leguminosae which contain them, consist of leucocyanidin and leucodelphinidin. In most of the species (sainfoin, Onobrychis viciaefolia Scop. especially) the tannins are di

Luteoforol, prepared by reduction of eriodictyl with sodium borohydride, is characterized by the formation of luteolinidin when heated with aqueous HCl and by the formation of a blue-rose colour when treated with cold mineral acid. The latter propert

The RF values, accurate and reproducible to ± 0.02, in butanol-acetic acid and m-cresol-acetic-acid of a number of naturally-occurring flavones, anthocyanins, and related compounds have been determined; also the RF values of a number of hydroxy-, me
