White powder, soluble in organic solvents such as methanol, ethanol, and DMSO, derived from the dried roots of Ophiopogon japonicus.
Methylophiopogonone B, a homoisoflavonoidal compound that could be isolated from Ophiopogonis Tiber, could scavenge OH and H2O2 in vitro to a certain extent[1][2].
ChEBI: Methylophiopogonone B is a homoisoflavonoid that is 4H-1-benzopyran-4-one substituted by hydroxy groups at positions 5 and 7, methyl groups at positions 6 and 8 and a (4-methoxyphenyl)methyl group at position 3 respectively. It has a role as a plant metabolite. It is a homoisoflavonoid, a member of resorcinols and a monomethoxybenzene.
