Q. Li et al., Isolation, identification and physiological activities of 2-(1 ',2 ',3 ',4'-tetrahydroxybutyl)-6-(2 '' 3 '',4 ''-trihydroxybutyl)-pyrazine from panax notoginseng, CHEM J CH U, 22(11), 2001, pp. 1824-1828
A water soluble polyhydroxy derivative of 1, 4-diazine has been isolated fr
om panax notoginseng for the first time. Its structure was determined as 2-
(1', 2', 3', 4'-tetrahydroxybutyl)-6-(2", 3", 4"-trihydroxybutyl)-pyrazine
by MS, NMR, H-1-H-1 COSY, H-1-C-13 COSY, HMBC etc., it was also confirmed b
y the synthesized sample. Its activity of anticancer was studied.
