Ophiopogon japonicus Root Source & Identity
The botanical entity is Ophiopogon japonicus (Thunb.) Ker Gawl., the dwarf lilyturf of the Asparagaceae, a grass-like evergreen perennial with spindle-shaped tuberous roots. The part used is the tuberous root. Leaf and flower stem are not part of this Ophiopogon japonicus extract.
Look-alike roots are a known source of mix-ups. The tubers of Liriope species are used as substitutes under the Chinese name mai dong, so the Latin binomial should be quoted on every specification. The root holds steroidal saponins, homoisoflavonoids and fructan-type polysaccharides, named here only as constituent families.
