Objectives: Oxidative stress plays a key role in chronic and acute brain disorders and neuronal damage associated with Alzheimer disease (AD) and other neurodegeneration symptoms. The neuroprotective effects of berberine and Berberis vulgaris (barberry) root extract against apoptosis induced by hydrogen peroxide (H₂O₂) in the human SH-SY5Y cell line were studied. Methods: The methanolic extraction of barberry root was performed using a maceration procedure. Oxidative stress was induced in SH-SY5Y cells by H₂O₂, and an MTT assay was applied to evaluate the neuroprotective effects of berberine and barberry root extract. The cells were pretreated with the half maximal inhibitory concentration (IC₅₀) of each compound (including berberine, barberry root extract, and H₂O₂), and the anti-apoptotic effects of all components were investigated using RT-PCR. Results: The SH-SY5Y cell viability increased in both groups exposed to 75 and 150 ppm barberry extract compared with that in the H₂O₂-treated group. The data showed that exposing SH-SY5Y cells to 30 ppm berberine significantly increased the cell viability compared with the H₂O₂-treated group; treatment with 150 and 300 ppm berberine and H₂O₂ significantly decreased the SH-SY5Y cell viability and was associated with berberine cytotoxicity. The mRNA levels of Bax decreased significantly under treatment with berberine at 30 ppm compared with the control group. A significant increase in Bcl-2 expression was observed only after treatment with the IC₅₀ of berberine. The expression level of Bcl-2 in cells exposed to both berberine and barberry extracts was also significantly higher than that in cells exposed to H₂O₂. Conclusion: The outcomes of this study suggest that treatment of SH-SY5Y cells with barberry extract and berberine could suppress apoptosis by regulating the actions of Bcl-2 family members.

In order to analysis on color difference of yellow natural dyes, I have dyed cellulose and protein fabrics. The results of experiment have been analysed by wavelength of maximum absorption, amounts of dye uptake, color difference, Hunter's value and Munsell's value. The results from these analyses are as follows : Bud of pagoda tree, Amur cork, and Curcuma showed greenish yellow color, Gardenia Jasminoides showed reddish yellow color. Barberry root showed reddish yellow color with post-mordanting method on cellulose fabric. Moreover, Dupioni silk was dyed in reddish yellow color by Barberry root and Rhubarb. In addition to Chroma index, Gardenia Jasminoides and Curcuma showed clear color overall. However, dyeing rayon and silk by Barberry root, and dyeing silk by Rhubarb showed clear color. Comparing all the results to actual dyed materials, Bud of pagoda tree had small dye uptake, and both ${\Delta}a$ and ${\Delta}b$ value were short which can't recognized the yellow color easily. Dye uptake of Amur cork and Gardenia Jasminoides was small just like Bud of pagoda tree. However, ${\Delta}b$ value order was Gardenia Jasminoides>Amur cork>Bud of pagoda tree. Therefore, Gardenia Jasminoides recognized reddish yellow because of big value of red color and yellow color. In case of Barberry root and Rhubarb which have larger dye uptake, Baberry root recognized yellow color on rayon only, and couldn't recognized yellow color on bleached cotton fabric, ramie, silk, and dupioni silk. Rhubarb recognized yellow color on rayon with pre-mordanting method only, but recognized silk and dupioni silk as brown like color. Moreover, we could not analyze color by dye uptake, Lab, and H(v/c) for Barberry root and Rhubarb. As a result, I think we need to attach color table for the research paper which handled the color of dyeing materials.

Objectives: The goal of this project was to measure the antibacterial effectiveness of Hwangryunhaedok-tang (barberry root decoction for detoxification) and its constituents. All of the active ingredients including the final product were prepared using high-pressure sterilization for use as medicinal eye drops. The varying forms of Hwangryunhaedok-tang (barberry root decoction for detoxification) were used to treat Staphylococcus epidermidis and Enterococcus faecalis which are found in keratitis. Methods: The antibacterial effect was measured by observing the presence or absence of antimicrobial activity when treated with varying concentrations of Hwangryunhaedok-tang extract. The tests were performed using a dosage of $70{\mu}l$ dosages of 100%, 50%, 10% and 1% the extracted solution by the minimum growth inhibitory concentration measurement. Antimicrobial activity was measured by examining the correlation between dosage strength and bacterial activity from $70{\mu}l$ to $10{\mu}l$ at the same concentration. Results: 1. Hwangryunhaedok-tang (barberry root decoction for detoxification), Phellodendri Cortex, and gardenia didn't show any antimicrobial effects against S. aureus, S. epidermidis, or E. faecalis. 2. Barberry root showed antimicrobial effects against S. aureus and S. epidermidis depending on the levels of concentration but didn't show any antimicrobial effects against E. faecalis. 3. Skullcap showed antimicrobial effects against S. aureus and S. epidermidis when a dosage of 100% extract $70{\mu}l$ was used. However, did not show any antimicrobial effects at all against E. faecalis. Conclusions: Hwangryunhaedok-tang (barberry root decoction for detoxification) and its constituents such as barberry root, phellodendri cortex, skullcap, and gardenia, can be used as an alternative to antibiotic medicinal eye drops to treat keratitis. However, further research on effective uses of and efficient extraction methods are needed.

Berberis tinctoria (Berberidaceae), commonly known as Nilgiri Barberry is a common allied species to B. aristata, used in India Traditional Systems of Medicine by the name of 'Daruharidra' for skin disease, jaundice, affection of eyes, and rheumatism. Keeping this in view, in the present study attempts have been made to identify marker characters of B. tinctoria. Some of the diagnostic features of the root are patches of pericyclic fibre, pitted sclerieds, crystals, berberine containing cells and heterocyclic medullary rays. Besides, the physicochemical characters such as total ash; acid insoluble ash; alcohol and water soluble extractive; tannins; sugar and starch percentages has also shown some variations. The percentage of berberine as berberine hydrochloride was also calculated through HPTLC densitometric method and it was found almost similar to B. aristata, B. asiatica and B. chitria i.e. 3.36%. Thus it can be explored as a possible source of substitute to B.aristata.

Mesoporous alumina was synthesized using bayberry tannin (BT) as template. This novel synthesis strategy was based on a precipitation method associated with aluminum nitrate as the source of aluminum in an aqueous system. $N_2$ adsorption/desorption, XRD, SEM and TEM were used to characterize the as-prepared mesoporous alumina. The results showed that the mesoporous alumina possessed crystalline pore wall, high specific surface area, narrow pore distribution and excellent thermal stability. Moreover, the surface area and pore size of the mesoporous alumina can be tuned by changing the experimental parameters. Further, the mesoporous alumina was investigated as the support of palladium catalyst ($Pd-Al_2O_3{^*}$) for the hydrogenation of propenyl, styrene and linoleic acid. For comparison, the reference catalyst ($Pd-Al_2O_3$) prepared without barberry tannin was also employed for the catalytic hydrogenation. The experimental results showed that $Pd-Al_2O_3{^*}$ exhibited the superior catalytic performance than $Pd-Al_2O_3$ for all the investigated substrates, especially for the hydrogenation of linoleic acid with larger molecular.

In order to analysis on color difference of natural dyes, I have dyed Hanji, cotton, silk fabric and exposed them to carbon arc light. The results of experiment have been analysed by Munsell's value, and compared the difference of colors which were recognized visually. Gardenia Jasminoides is monogenetic dye, but it gained darker color by pre-mordanting method used aluminum mordant agent and greenish yellow color by ferric mordant agent. whereas Curcuma, an Amur cork, and bud of pagoda tree are shown as greenish yellow color, and A barberry root, Betel nut, and Rhubarb are shown as reddish yellow color. these gained khaki colored dyed fabric by ferric mordanting. In addition, Sappan wood showed great result in pre-mordanting. Especially, it gained dark red color by aluminum pre-mordanting. The pink color was shown by post-mordanting. and Logwood showed great dyeing result in Hanji and cotton better than silk. Specially pre-mordanting was effective. Hanji and cotton showed greenish blue color by aluminum pre-mordanting, and silk showed brown color. However the color, which was recognized visually, differed from colorimeter sometimes. Therefore, such color table might be necessary for the natural dyeing.

Hair loss affects both men and women of all ages and often significantly affects social and psychologic health. Recent therapeutic approach for hair loss such as finasteride and minoxidil focused on regulation of hormonal system blood flow. However, long-term use of these drugs caused adverse effects. To develop herbal medicine for therapeutic effect on hair growth, here we screened the 10 medicinal herbs (Red ginseng, Licorice, Ulmus, Barberry root, Lycium root, Rehmanniae radix crudus, Sophora root, Sweet flag, Polygala root, Achyranthes) based on oriental medicine literature. We measured cytotoxicity, anti-oxidant activity, and $5-{\alpha}$ reductase inhibitory effect of the herbal medicine on human dermal papilla (DP) cells to investigate therapeutic effect of the herbal medicine. Treatment of the 1% herbal medicine did not show any cytotoxic effects, and cell growth was increased by treatment of the 0.1% herbal medicine. In addition, the herbal medicine showed stronger antioxidant activity than resveratrol and comparable inhibitory activity of $5-{\alpha}$ reductase with finasteride. Furthermore, when applied to in vivo mouse model, we also observed increases in the number and length of hair of the herbal medicine-treated group. These results suggest that the herbal medicine promotes hair growth by its antioxidant activity and inhibitory activity of $5-{\alpha}$ reductase and might therefore be a promising hair growth-promoting agent.
