%X A detailed chemical investigation of the red resins from Dracaena cochinchinensis (Chinese dragon¡¯s blood) yielded five new flavonoid oligomers, named cochinchinenins D-H (1¨C5), together with a known biflavonoid, cinnabarone (6), and a mixture of two known biflavonoids, socotrin-4¡ä-ol (7) and homoisosocotrin-4¡ä-ol (8). Of these new compounds, 1¨C3 were biflavonoids and 4 and 5 were triflavonoids. Their structures were determined on the basis of spectroscopic analysis. The isolated compounds were tested for cytotoxicity (Cdc25), antibacterial (PEPT) and antifungal (YNG) activities.
