M. Neves et al., 3 TRITERPENOIDS AND ONE FLAVONOID FROM THE LIVERWORT ASTERELLA-BLUMEANA GROWN IN-VITRO, PTR. Phytotherapy research, 12, 1998, pp. 21-24
This is the first report on the chemical constituents of Asterella blu
meana. Three triterpenoids (22-hydroxyhopane, 22,29-dihydroxyhopane, 6
alpha,22-dihydroxyhopane) and one flavonoid (isoscutellarein-7,8,4'-t
rimethyl ether) were isolated from the CH2Cl2 extract of the liverwort
Asterella blumeana grown in vitro. The structures of isolated compoun
ds were established by spectroscopic methods (UV, EI mass spectroscopy
, H-1- and C-13-NMR). 22,29-dihydroxyhopane is a new natural compound.
