FIGURE 1.12 Specific fragmentations of the C-glycosylflavones isoorientin and isovitexin. [Pg.26]

Forty new compounds have been reported in this class during the last 12 years. Many references concerned the well-known O-acetyl, O-caffeoyl, O-p-coumaroyl, and O-feruloyl esters. The p-hydroxybenzoyl and p-methoxybenzoyl groups gave rise to two new natural 6"-0-acylated isoorientin derivatives in Polygonum perfoliatumin A and B. [Pg.886]

In the case of isoorientin 6"-0-caffeate isolated from Gentiana arisanensis, the C NMR spectrum was assigned by H-decoupled spectra, DEPT pulse sequence, H- C COSY spectrum, long-range C- H COSY, and NOESY experiments the H NMR spectrum was analyzed with the aid of H- H COSY and H- C COSY. [Pg.893]

C-Glycosylflavones of Arum palaestinum showed antimicrobial activity against E. coli and Staphylococcus aureus, which were the most susceptible bacteria to vitexin and isoorientin. Antimicrobial activity was also described for C-glycosylflavones from Otostegia fruticosa vicenm-2. ... [Pg.900]

Arum palaestinum contains isoorientin and vitexin, which were studied for their antispasmodic activity on isolated organs. Isoorientin in concentrations ranging from 10 to 6 X 10 M decreased the frequency and the amplitude of the phasic contractions of uterine... [Pg.900]
