摘要：

Two rare anthocyanins, cyanidin 3-(6-malonylglucoside)-7,3'-di(6-sinapylglucoside) and the demalonyl derivative, were characterised as the purple floral pigments of Dendrobium cv. 'Pompadour'. Nine known flavonol glycosides were also identified, including the 3-rutinoside7-glucosides of kaempferol and quercetin. One new glycoside was detected: the ferulyl ester of quercetin 7-rutinoside-7-glucoside. These flavonoid patterns are typical for plants in the family Orchidaceae. (C) 2002 Elsevier Science Ltd.
