Effect of combinations of quercetin (Q) and licorice (L) extract on bone formation
in murine calvarial tissues. Calvarial tissues were harvested, incubated with
botanical extracts for 7 d, and examined using histomorphometric analysis. The
concentration of either quercetin or licorice extract was kept constant while the
other extract concentration was varied. (a) Quercetin constant at 1 µg/ml; (b)
quercetin constant at 0·2 µg/ml; (c) licorice constant at 2 µg/ml; (d) licorice
constant at 0·2 µg/ml. Results are expressed as percentage of area of new bone
(mm2 × 10−3). (
), Control (untreated)
samples. Values are means, with standard errors represented by vertical bars.
