  • This research was performed to determine the production of lovastatin and its HMG-CoA reductase activity produced by fruit bodies and mycelial liquid cultures of domestic edible mushrooms (8 fungal strains). By deter-mining TLC analysis for the confirmation of the presence of lovastatin, all the extracts from fruit bodies and mycelial liquid culture showed same Rf value (0.46), whick was identical to that of the standard lovastatin. In order to extract lovastatin from fruit body, the mixture of water/acetonitrile/methanol was chosen as the most effective solvent. Extracts from fruit body and mycelial liquid culture of pleurotus ostreatus produced the high-est lovastatin 0.98 mg/g based on dry biomass, and 21.90 mg/L, respectively. In the inhibition rate of 3-hydroxy-3-methylglutaryl-CoA (HMG-CoA) reductase, the highest was obtained in P. ostreatus as 67.8% among fruit bodies, and the rates of mycelial liquid culture extracts from P. ostreatus and Laetiporus sulphureus were 37.2% and 29.1%, respectively. Unusually L. sulphureus showed high inhibition rate with low content of lovastatin due to the contribution of campesterol and gamma-sitosterol with hypocholesterolemic activity as metabolites.

  • This study was done to investigated the phytosterol compositions of safflower (Carthamus tinctorius L.) seed. The phytoestrogen activity was also determined using CAT-ELISA Kit in ethanol extract of safflower seed. The phytosterol of safflower seeds was identified using gas chromatography-mass spectrometry after saponification of the oils. The phytosterol content and composition of safflower seed oils were 4% and identified stigmast-5-en-3-ol (3$\beta$, 24S)-form, ${\gamma}$-sitosterol (clionasterol) with Wiley MS spectrum library. The synergistic effect of human estrogen receptor (hER) has been investigated using a minimal chimeric promoters composed of the TATA region of the adenovirus-2 major late promoter (A22MLP) and two consensus perfectly polindromic Xenopus vitellogenin A2 gene estrogen responsive elements (XVEREl19). Transient transfection experiments in tile human breast adenocarcinoma cell line MCF-7, which is known to express the estrogen receptor endogenously, revealed that phytoestrogen from Carthamus tinctorius L. acts as estrogen. We have observed the transcriptional activities stimulated methanol and ethanol extract of safflower seed in MCF-7, were 0.43 and 0.37 respectively, compared to that by $\beta$-estradiol as 1.0. Our data showed that safflower seeds have estrogenic activity methanol and ethanol extracts and ethanol lower than that of $\beta$-estradiol. This result provides the first evidence that the beneficial effect of safflower seeds may be mediated, at least in part, by the stimulating effect of phytoestrogen ell bone-protecting.

  • 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.

  • A novel chlorinated diterpene quinone methide; chlorosmaridione (7-chloro-11-hydroxy-abeita-7,9(11),13-triene-6,12-diode) was isolated from petroleum ether extract of the stems of Rosemarinus officinalis L. growing in Egypt. In addition, ${\beta}-sitosterol$, stigmasterol, lupeol acetate, ${\alpha}-amyrin,\;{\beta}-amyrin$, lupeol, acetyloleanolic acid, acetylursolic acid taxodione, horminone, and cryptotanshinone were also identified. Chemical structures of the isolated compounds have been elucidated on the bases of physical, chemical, and spectral data including IR, UV, MS, 1D-and 2D-NMR spectra.

  • 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.
