Five major flavonoids induced by chitin in Cephalocereus senilis cell suspension cultures have been reported previously. We describe here five minor induced flavonoids including two new and three known ones. The two new compounds are (2S)-5,6,7-trihydroxyflavanone 7-glucoside and baicalein 7-(6''-malonylglucoside).
... 9 On this basis compound 2 was characterized as chrysin, a flavone previously known from many plants. The third compound (3) appeared as brown crystals that melted at 265-266 o C. 10 The HR-EIMS of compound (3) showed the molecular ion peak at m/z 270.2438 [M + ], which led to establish the molecular formula as C 15 H 10 O 5 . The 13 C NMR spectrum ( Table 2) exhibited 15 carbon signals, which were accounted for seven methine and eight quaternary carbons. ...
