Studies on periderm. II. Anthocyanidins in secondary periderm tissue of amabilis fir, grand fir, western hemlock, and western red cedar
Keyword(s):
By using a mild method, which precludes the possibility of pigment hydrolysis during extraction and processing, the occurrence of anthocyanidins in the free state has been detected in the normal secondary periderm tissues (rhytidomal region) of amabilis fir (Abies amabilis (Dougl.) Forbes), grand fir (Abies grandis (Dougl.) Lindl.), western hemlock (Tsuga heterophylla (Raf.) Sarg.), and western red cedar (Thuja plicata Donn.). Cyanidin was present in all species. Pelargonidin was present in western hemlock and most likely also in western red cedar.
