Abstract
Total phenolics, condensed tannins, proanthocyanidins, leucoanthocyanins, and protein-precipitable phenolics were determined in young and mature leaves of Quercus incana, Quercus semecarpifolia, and Quercus ilex. Total phenols in young leaves of both Q. semecarpifolia and Q. incana were higher, but no difference was observed for Q. ilex. Condensed tannins increased with maturity except in the case of Q. ilex where no change was observed; the same trend was observed for proanthocyanidins and leucoanthocyanins. Protein-precipitable phenolics and total phenols were highest in Q. semecarpifolia and lowest in Q. ilex. The protein-precipitable phenolics had an excellent correlation (r = 0.995) with total phenols.
