  • Spinoside, new coumaroyl flavone glycoside was isolated from the n-butanol fraction of the mathanolic extract of the whole plant of Amaranthus spinosus and assigned the structure 7-pcoumaroyl apigenin 4-O-${\beta}$ -D-glucopyranoside (1) on the basis of spectroscopic techniques including 1D and 2D NMR spectroscopy. In addition ${\alpha}$ - xylofuranosyl uracil (2), ${\beta}$ -D-ribofuranosyl adenine (3) and ${\beta}$ -sitosterol glucoside (4) have also been isolated for the first time from this species.

  • Achillea sibirica Ledeb. is widely distributed in Korea and has been often used as folk medicine in peptic and tonic. As one of our searches for bioactive (anti oxidation) compounds from medicinal plants, we studied Achillea sibirica Ledeb. (Compositae). Antioxidant activity of Achillea sibirica was determined by measuring lipid peroxide produced when a mouse liver homogenate was exposed at $90^{\circ}C$ using 2-thiobarbituric acid (TBA) and by evaluation the radical scavenging activity on 1, 1-diphenyl-2-picrylhydrazyl (DPPH) radical. Whole parts of Achillea sibirica was extracted with methanol and its extracts was fractionated with organic solvent; n-Hexane, methylene chloride, ethyl acetate, n-Butanol. EtOAc fraction exhibited antioxidant activity and From its, two flavonoid glycosides were isolated by silica gel and gel filtration colume chromatography and identified to kampferol 3-O-glucoside and luteolin 7-O-neo-hesperidoside, respectively, by physico-chemical and spectroscopical method. At antioxidant activity test for two compounds isolated, antioxidant activity was showed too. And from hexane fraction sterol was is isolated and identificated to mixture of campesterol, stigmasterol, and ${\beta}-sitosterol$.

  • Sajabalssuk (Artemisia herba) was extracted with 80% aqueous MeOH, and the concentrated extract was partitioned with EtOAc, n-BuOH and $H_2O$, successively. From the EtOAc and n-BuOH fractions, four sterols were isolated through the repeated silica gel and ODS column chromatographies. From the results of physico-chemical data including NMR, MS and IR, the chemical structures of the sterols were determined as ${\beta}-sitosterol$ (1), ergosterol peroxide (2), stigmasterol (3) and daucosterol (4). They were the first to be isolated from Sajabalssuk (Artemisia herba).

  • In previous studies, we confirmed the effective antimicrobial activity of fermented Dendropanax morbifera leaf/branch extracts with Lactobacillus plantarum ilchiwhangchil 1785 and Lactobacillus plantarum ilchiwhangchil 2020. In this study, we investigated the hair growth effect of D. morbifera leaf/branch extracts fermented with L. plantarum ilchiwhangchil 1785 and L. plantarum ilchiwhangchil 2020 on human hair dermal papilla cells. The growth rate of human hair dermal papilla cells treated with fermented extracts in the range of 1 to $10{\mu}g/ml$ significantly increased in a concentration-dependent manner, without increasing cell death. Double staining studies showed that the growth of cells treated with fermented D. morbifera leaf/branch extracts was more active than that of control cells. Moreover, the cells treated with the fermented D. morbifera leaf/branch extracts exhibited a 18.84% and 23.31% increase in cell mobility, respectively, as compared with that of the untreated cells. High-performance liquid chromatography (HPLC) was used to determine the active agents responsible for hair growth. The results showed that the content of ${\beta}$-sitosterol, which is known to affect hair growth, increased about 10 times in the fermentation process of D. morbifera leaf/branch extracts. Taken together, the findings confirm that fermented Dendropanax morbifera leaf/branch extracts promote hair growth.

  • Five compounds$(I{\sim}V)$ were isolated from the roots of Peucedanum terebinthacem growing in Korea. Compounds I, IV and V are ${\beta}-sitosterol$, bergapten and umbelliferone, respectively. IR and NMR spectra of compounds II (mp. $190^{\circ}$) and III(mp. $111{\sim}120^{\circ}$), both white needle crystalls, indicate that compounds II is a furocoumarin and that compound III, yielding decursinol upon saponification, is a pyranocoumarin.

  • Zizyphus jujuba, Z. jujuba var. inermis, and Z. jujuba for. hoonensis were cultured in korea. Zizyphus seeds are used for insomnia, sedation and sleeping-dropsy in many oriental medical prescriptions. Three Zizyphus species in Korea were investigated for their chemical composition. The components in methanol extracts of the fruit and seed were separated by TLC, PPC and were identified with known compounds. Sucrose, galactose, glucose, fructose and ${\beta}-sitosterol$ were isolated from the fruit of Zizyphus jujuba for. hoonensis.
