  • Objectives: This study was conducted to evaluate the inhibitory effect of Melia Fructus extract on osteoclast differentiation. Methods: MTT-assay was performed to estimate cytotoxicity of Melia Fructus extract in BMMs stimulated with M-CSF. TRAP staining, TRAP activity and Real-time PCR were performed to know the inhibitory effect on osteoclast differentiation. Actin ring formation were analysed to observe the effect of Melia Fructus extract. Results: Melia Fructus extract decreased the number of TRAP positive cells and the expression of NFATc1 gene, c-Fos gene, TRAP and OSCAR in BMMs stimulated with RANKL. Melia Fructus extract has no cytotoxicity at the concentration used in this study. Melia Fructus extract restrained the formation of actin ring. Melia Fructus inhibited NF-${\kappa}B$ activity by inducing degradation of p-$IkB{\alpha}$. Conclusions: Melia Fructus has the inhibitory effect of osteocalst differentiation and bone resorption. Further studies are needed to treat osteoporosis by herbal medicine containing Melia Fructus.

  • Meliae toosendan Fructus, the seed of Pagoda tree, Melia toosendan Sieb. et Zucc. (Meliaceae), has been used as a liver protective herbal drug in the Orient. Administration of seed oil to hyperlipedemic rats revealed the lipid lowering effects in serum and liver tissue without any toxicity in body weight increase and liver function.

  • Meliae toosendan Fructus is the fruit of Melia toosendan $S_{IEB}$. et $Z_{UCC}$. (Meliaceae), which is written in oriental terminology as clearing heat and drying dampness, and also explained using liver, stomach and small intestine for channels entered. Among the five fractions prepared from methanol whole extractive of the herb, the chloroform fraction which suggests the presence of triterpenoid, flavonoid and alkaloid stimulated the activities of drug metabolizing enzymes and bile secretion and lowered the serum transaminase activities of liver damaged by carbon tetrachloride.

  • A triterpenoid(melianone) and a limonoid(28-deacetyl sendanin) were isolated from the chloroform fraction of Meliae toosendan Fructus, the rippen fruits of Melia toosendan SIEB. et ZUCC.(Meliaceae) and were applied to serial experiments to clarify the liver protective activities. We found that the compounds promoted slightly the drug metabolizing enzyme activities and decreased serum transaminase activities which was elevated by carbon tetrachloride intoxication. And also they slightly increased the secretion of bile juice in rat.

  • To produce bioactivity-strengthen medicinal herbs, the 36 medicinal herbs which have antioxidation or blood circulation activity, were solid fermented using Phellinus baumii mycelium. Most of medicinal herbs, except Chrysanthemum indicum (flower), Zizyphus jujuba Miller (fructus), Aconitum koreanum R. Raymond (root), Magnolia denu-data (flower), and Polygonatum sibiricum Redt (root bark), showed good fermentation at $25^{\circ}C$ for 20 days under 90% of relative humidity. The poor fermentations of the herbs could be explained by lack of nutrient, structural rigidity, and the content of antifungal substance. After fermentation, the average water content of herbs were increased to $67.21{\pm}11.43%$ from $30.84{\pm}15.67%$, but the average pH and average methanol extraction ratio were slightly decreased to $11.16{\pm}7.06%$ and $4.83{\pm}0.73$ from $13.91{\pm}12.22%$ and $5.06{\pm}0.87$, respectively. The analysis of thrombin inhibition and DPPH scavenging activity of the methanol extracts of herbs showed that thrombin inhibition activities of the fermented Drynaria fortunei Kunze, Melia azedarach var. japonica, Prunus persica and Orostachys japonicus, and DPPH scavenging activities of the fermented Polygala tenuifolia, Scrophularia buergeriana, Angelica dahurica, Drynariafortunei Kunze, Cyperus rotundus, and Boschniakia rossica were increased as compared with those activities of non-fermented its cognate herbs. Our results suggest that the production of bioactivity-strengthen medicinal herbs is possible by solid fermentation of Phellinus baumii mycelium, as fermented Drynaria fortunei Kunze showed increased antioxidant and thrombin inhibitory activities than those of non-fermented herbs.
