The flavone tricin (5,7,4'-trihydroxy-3',5'-dimethoxyflavone) is considered to be a selective potent inhibitor of different cancer cell lines and a potential colorectal cancer chemopreventive agent. In this paper we describe a reliable UHPLC-UV-ESIMS method for the determination of tricin in Huperzia plants used in the traditional medicine of the Saraguro community living in Southern Ecuador. An unusually high amount of tricin was found in H. brevifolia and H. compacta, which exceeded the content of this flavone determined so far in other plants.

The flavonoid contents of different bamboo-leaf extracts and their relationships to antioxidant activity were investigated in this study by preparing nine samples using two commercially available bamboo-leaf extract products and seven bamboo-leaf extracts such as . A high performance liquid chromatography (HPLC) method was established to determine seven flavonoid components (orientin, isoorientin, vitexin, isovitexin, tricin, luteolin and luteoloside) in these samples, which were separated using a SymmetryShield RP8 column (250 mm×4.6 mm, 5 μm) under gradient-elution conditions using acetonitrile as mobile phase A and 0.

The lignin from tritordeum straw, a hybrid cereal from crossbreeding of durum wheat and wild barley, was isolated and chemically characterized. Its composition and structure were studied by analytical pyrolysis (Py-GC/MS), nuclear magnetic resonance spectroscopy (NMR), Derivatization Followed by Reductive Cleavage (DFRC) method, and gel permeation chromatography (GPC). The data revealed an enrichment of guaiacyl (G) units (H:G:S of 3:61:36), which had a significant impact on the distribution of inter-unit linkages.

This review focuses on the synthesis and biological activity of flavones and their related flavonoidic compounds, namely flavonols and aurones. Among the biological activities of natural and synthetic flavones and aurones, their anticancer, antioxidant, and antimicrobial properties are highlighted and detailed in this review. Starting from the structures of natural flavones acting on multiple anticancer targets (myricetin, genkwanin, and other structurally related compounds), new flavone analogs were recently designed and evaluated for their anticancer activity.
