This study assessed the whitening and anti-aging effects of the Cistanche deserticola extract, to develop a cosmetic substance. The cell viability of the Cistanche deserticola extract was evaluated in B16F10 melanoma cells by the MTT (3-(4,5-dimethylthaiazol-2-yl)-2,5-diphenyl tetrazolium bromide) assay. The cell viability of the extract was determined to be 90% at 4mg/ml concentration. Furthermore, the tyrosinase, collagenase, and elastase mRNA expression level were measured by RT-PCR, using the Cistanche deserticola extract treated B16F10 melanoma cells. At 4 mg/ml concentration, mRNA expression level of tyrosinase, collagenase, and elastase was dramatically decreased to 80.9%, 37.6%, and 70.9%, respectively. The antioxidant activity of the Cistanche deserticola extract was determined by DPPH free radical scavenging. The DPPH free radical scavenging capacities ranged from 70.6% to 82.6%, when evaluated from 2 mg/ml to 10mg/ml concentrations. The effects of whitening and anti-aging of the Cistanche deserticola extracts were examined at 2, 4, 6, 8, and 10 mg/ml concentration. Tyrosinase activities were inhibited from 66.8% to 78.5%, elastase activities were inhibited from 67.6% to 79.3%, collagenase activities were inhibited from 72.3% to 83.6%, and hyaluronidase activities were inhibited from 65.8% to 69.2%, respectively. These data suggest that the Cistanche deserticola extract is effective in whitening and anti-aging; therefore, it is considered to be a functional cosmetic material in cosmetic products.

Purpose : This study was undertaken to evaluate the effects of the different administration duration of Epimedium Herb extract solution on the spermatogenic abilities such as concentration, motility and morphological normality of sperm from the testis and the activities of sperm hyaluronidase. Methods : We used the 2-month-old mice and administered the extract solution of Epimedium Herb 0.3 ml/g/day for 30, 60, 90 and 120 days. The control group was administered the normal saline as the same way. We examined the number of total, motile and normal sperm from the cauda epididymis, the activities of sperm hyaluronidase. Also we observed changes of isolated testis before and after administration of Epimedium Herb extract solutions in the mice. And we compared the testicular tissue especially seminiferous tubules with the control and treated group by histochemical methods. Results : The significant differences were observed in the concentration of total sperm and normality of spermatozoa of the Epimedium Herb extract solution administered groups compared to the control group in 60, 90 and 120 days groups. The significant differences were observed the motility of the Epimedium Herb extract solution administered groups compared to the control group in 60 days group. In the histological analysis of the testicular tissues, the enlargement of testicular lobe diameter and apparent vasculogenesis between testicular lobes were observed in the Epimedium Herb extract solution administered groups compared to the control group, respectively. And the activity of hyaluronidase was significantly increased in the Epimedium Herb extract solution administered groups compared to the control group. Conclusion : This study shows that Epimedium Herb has the beneficial effect on the concentration, morphology and motility of sperm, the testicular tissues and the activities of sperm hyaluronidse in 60 days administration group. We can suggest that Epimedium Herb extract solution be useful for the treatment of male sexual dysfunction and infertility.

To establish the in vitro culture system and quantitation for chondrogenesis, and to investigate the relationship between cell aggregation and chondrogenesis, chick limb bud mesenchymal cells of Hamburger-Hamilton stage 23/24 were micromass cultured in various cell densities. The chondrogenesis was assayed based on checking the alcian blue-stained nodule numbers, the amount of alcian blue extraded, the change in cell numbers, the rate of [35 S] sulfate incorporation and expression of type II collagen. Mesenchymal cells plated with an initial density of high (1 x 107 cells/ml)- and intermediates (5. $\times$ 106 cells/ml)-density were differentiated into cartilage. On the other hand, the cells of low density (2 x 106 cells/mi, 5 $\times$ 105 cells/ml) of stage 23/24 cells and the stage 18/19 cells in three kinds of cell density did not differentiate into cartilage even though the cells formed an aggregated core at the center of cultured mass. From these results and others obtained in this study, it can be stated that the stage 23/24 mesenchymal cells are likely to pass over the aggregation step and have the potentiality to differentiate into chondrocytes. Thus chondrogenesis in vitro can be observed when mesenchymal cells are plated over the threshold density of 5 $\times$ 106 cells/ml. Hyaluronidase (HAase) activity was relatively constant throughout the culture, suggesting that the role of HAase may not be important for the cells of stage 23/24.

To evaluate antiinflammation of Aloe vera peel, antiimflammation substances were extracted from Aloe vera peel and identified, and we investigated the effect of the its substance the inhibitory effect on the activity of hyaluoronidase, elastase, collagenase and prostaglandin endoperoxide synthase. The water extract from Aloe vera peel were successfully purified with solvent fractionation, silica gel column chromatography, preparative thin layer chromatography and UV spectrometer. Two purified active substances were identified as aloe-emodin and barbaloin by Mass Spectrometer, $^1H-NMR$ and FT-IR. Aloe-emodin and barbaloin. $IC_{50}$ values of aloe-emodin and barbaloin against hyaluronidase activity were 40 and $70\;{\mu}g/mL$, respectively. Leuckocyte elastase, which is related to the destruction of various tissue, $IC_{50}$ values of them were 50 and $60\;{\mu}g/mL$, respectively. $IC_{50}$ values of aloe-emodin and barbaloin against collagenase activity were 40 and $60\;{\mu}g/mL$, respectively. and $IC_{50}$ values of aloe-emodin and barbaloin aganist the prostaglandin endoperoxide synthase, which play an important role in inflammatory reactions, were 40 and $70\;{\mu}g/mL$, respectively. Inhibitory effects of aloe-emodin, barbaloin and aspirin against carrageenan paw edema were 74.9, 52.9 and 51.9% as inhibiton percentage, respectively, at dose of 100 mg/kg and that of indomethancin was 49.7 at dose of 10 mg/kg. Cell cytotoxicity of barbaloin against human gingival cells was lower than that of aloe-emodin. Aloe-emodin and barbaloin did not show cytotoxicity against human gingival cells at concentration of 1.0 and $5.0\;{\mu}g/mL$, However, aloe-emodin and barbaloin showed less cytotoxicity than chlorhexidine, which usually have been used as the agent of anticaries and antiinflammation. These results suggested that aloe-emodin and barbaloin from Aloe vera peel have the effect of anticaries and antiinflammation.

A total of 20 extracts derived from different plant family commonly used in Indonesian traditional inflammation medicine were screened for their inhibitory effect on soybean lipoxygenase (SBL) and hyaluronidase (HAse) activity. Three methanol extracts, the bark of Cinnamomum burmanni (CB), the leaves of Piper betel (PB), and fruit of Barringtonia acutangula (BA) were found to have high inhibitory effects, whereas the methanol extract of the leaves of Mimusops elengi (ME) have medium inhibitory effect. The IC50 of CB, PB, BA and ME were found to be 21.7, 16.9, 39.1 and 62.8 g/$m\ell$, respectively. Among the tested extracts, only CB inhibited HAse (IC50 = 27g/$m\ell$). CB was successively fractionated with n-hexane, ethyl acetate, butanol and water. The EtOAc fraction having the strongest activity was fractionated and some compounds were isolated and purified by a preparative HPLC(Develosil ODS-HG-5 column). Coumarin and 2-hydroxy cinnamaldehyde. were identified through the analyses of UV-Vis absorption 1H-NMR, 13C-NMR and FAB+-MS spectra.

Propolis is a lipophilic, natural product prepared by mixing the exudates collected from various plants by honeybees with beeswax for the purpose of using to seal hive walls and to strengthen the borders of combs. Because of its versatile bioactivities, propolis has been attracting many investigators'interest. But the pharmacological studies on propolis has, to date, been exclusively performed for an alcohol extract, there is few information of water extract. Therefore, in this study, we investigated the various effects of water extract of Chinese propolis. The water extract of propolis and its fractions of organic solvents showed strong antioxidative activities, especially ether and ethylacetate fractions, and reduced the lipid peroxidation of rat liver in viro. Additionally the ether fraction of propolis (10 mg/ml) inhibited the activity of hyaluronidase by 50%. In vivo, the water extract of propolis considerably decreased s-GOT, s-GPT and s-LDH activities which represent for the hepatotoxicity induced by $CCl_4$ in rats, and prolonged the MST (Medium revival tinge) and ILS (Increasing in MST over control) by 18% in mice which inoculated with sarcoma 180 ascites cells. These results suggest that the water extract of propolis has various bioactivities as well as the alcohol extract.

In this study, Tongue fern (Pyrrosia lingua) plants that have been used traditionally as medicines. Their traditional medicinal uses, regions where indigenous people use the plants, parts of the plants used as medicines. This study was designed to assess the antioxidant and inhibition activities of extracts from P. lingua. In the P. lingua extracts was measured ethanol activity, 80.0% ethanol was high activity. The antioxidant activity was measured in 1,1-diphenyl-2-picrylhydrazyl (DPPH) and 2,2'-Azino-bis-(3-ethylbenzothiazoline-6-sulfonic acid) (ABTS), assays. DPPH and ABTS radical in this experiment, solid and phenolic of extract were tested, but only an average concentration of 100 ㎍/mL was used. However, the phenolic extract is shown phenolic activity reached a peak. Also, phenolic extracts ware reached peak water and ethanol extracts. As a result, using the phenolic extracts did other antioxidant assays such as DPPH, ABTS, protection factor, and thiobarbituric acid reactive substances at 50-200 ㎍/mL concentrations. The activity of elastase and collagenase, inhibiting their activities may retard skin aging. α-Glucosidase and α-amylase, inhibitors need to be explored for the benefit of postprandial hyperglycemia in diabetic patients. Activities of tyrosinase, hyaluronidase and xanthine oxidase inhibitors of these enzymes are increasingly important ingredients in cosmetics and medications to protect the skin against hyperpigmentation and skin aging. Inhibition effects were investigated using the P. lingua extracts at 50-200 ㎍/mL concentrations. The expression levels of enzyme inhibitions activities were decrease in dependent-concentrations manner when P. lingua extracts were treated.
