Abstract
<p>One anthocyanin and three flavones were isolated from the flowers of Tripora divaricata (Lamiaceae). They were identified as delphinidin 3-O-[(6″′-E-p-coumaroylglucosyl)-(1→2)-(6″-E-p-coumaroylglucoside)]-5-O-(6″′-malonylglucoside), apigenin 7-O-glucuronide, scutellarein 4′-methyl ether 7-O-glucuronide, and acacetin 7-O-glucuronide. In addition, we measured absorption spectra of intact petal and the buffer solutions (pH 5.6) containing isolated compounds for elucidation of the blue violet color development in T. divaricata. The absorption spectral curve of the buffer solution containing isolated anthocyanin showed the blue violet. Its color was identical to that of the intact flowers. These results indicate that the intramolecular copigmentation of anthocyanin mainly occurred in the blue violet flowers of T. divaricata.</p>
