SYRINGIN 4-O-BETA-GLUCOSIDE, A NEW PHENYLPROPANOID GLYCOSIDE, AND COSTUNOLIDE, A NITRIC-OXIDE SYNTHASE INHIBITOR, FROM THE STEM BARK OF MAGNOLIA-SIEBOLDII
Hj. Park et al., SYRINGIN 4-O-BETA-GLUCOSIDE, A NEW PHENYLPROPANOID GLYCOSIDE, AND COSTUNOLIDE, A NITRIC-OXIDE SYNTHASE INHIBITOR, FROM THE STEM BARK OF MAGNOLIA-SIEBOLDII, Journal of natural products, 59(12), 1996, pp. 1128-1130
Syringin 4-O-beta-glucoside (1), a new phenylpropanoid glycoside, and
costunolide (2) were isolated from the stem bath: of Magnolia sieboldi
i. The structures were determined by spectroscopic and chemical method
s. Costunolide (2) exhibited strong nitric oxide synthase inhibitory a
ctivity in the endotoxin-activated murine macrophage, J774.1.
