## Abstract Critical‐size bone defects usually require the use of autogenous bone grafts to heal. Harvesting of bone is traumatic, and results in high morbidity of donor site. A potential alternative to bone graft may be a bone substitute with adequate biocompatibility and biological properties pro

✦ Synopsis
This is the first report on the chemical constituents of Asterella blumeana. Three triterpenoids (22-hydroxyhopane, 22,29-dihydroxyhopane, 6a,22-dihydroxyhopane) and one flavonoid (isoscutellarein-7,8,4'-trimethyl ether) were isolated from the CH 2 Cl 2 extract of the liverwort Asterella blumeana grown in vitro. The structures of isolated compounds were established by spectroscopic methods (UV, EI mass spectroscopy, 1 H-and 13 C-NMR). 22,29-dihydroxyhopane is a new natural compound.
