'Whang Baig(黃柏)' is one of the crude drugs used mainly as a removing dampness, purging fire, detoxicating, and cleaning away heat of deficiency type. The botanical origin of the crude drug has never been studied pharmacognostically in Korea. To clarify the botanical origin of Whang Baig, the anatomical characteristics of Phellodendron amurense Rupr., Phellodendron insulare Nakai and Phellodendron molle Nakai were studied. As a result, it was clarified that Whang Baig from Korea was the bark of Phellodendron amurense and Phellodendron molle.

본 연구에서 소목 및 코치닐로 염색한 견직물, 그리고 소목과 황벽 및 코치닐과 황벽 복합 염색한 견직물의 염색성 및 기능성을 고찰하였다. 그 결과, 소목으로 염색한 견직물의 색상은 2.2R의 적색계열, 코치닐로 염색한 견직물은 3.0RP의 적자색 계열, 소목과 황벽으로 복합 염색한 견직물의 색상은 2.7YR로 주황색계열, 그리고 코치닐과 황벽으로 복합 염색한 견직물의 색상은 4.3R로 적색계열을 나타내었다. 항균성의 경우, Staphylococcus aureus에 대해서 코치닐로 염색한 견직물을 제외한 나머지 세 종류의 염색 견직물은 균 감소율이 91.1% 이상으로 우수한 항균효과를 나타내었다. 그리고 Klebsiella pneumoniae에 대해서 소목과 황벽 및 코치닐과 황벽으로 복합 염색한 견직물의 균감소율이 99.9%로 뛰어난 항균효과를 나타내었다.

Berberine, palmatine, and Phellodendron bark dye was prepared in methanol for HPLC-DAD-MS analysis of liquid dye. Silk was dyed using berberine, palmatine, and Phellodendron bark dye prepared in water. The dye was extracted from the dyed silk using the HCl/methanol/water (2:1:1 v/v/v) solvent system with a slight modification. The liquid dyes and the dye extracted from the silk samples dyed with the three dye sources were examined using the HPLC-DAD-MS analysis to simultaneously detect berberine and palmatine from the plant dye and the dyeings. Colorimetric measurement was carried out using a spectrophotometer to examine the color and the intensities of berberine, palmatine, and Phellodendron bark dyed silk samples. From the liquid dyes, berberine eluted at 5.21 min with the molecular cation m/z=336 and the UV spectrum confirming that the product was berberine. Palmatine eluted at 5.12 min with the molecular cation m/z=352 and the UV spectrum confirming that the product was palmatine. From the silk dyed with berberine and palmatine dye, berberine and palmatine species eluted at 5.35 min and 5.24 min, respectively. From the silk dyed with Phellodendron bark, berberine and palmatine were detected simultaneously at 5.35 min and 5.26 min, respectively. All three dyes had yellow hue while palmatine dyed silk showed the highest hue and chroma. Palmatine dyed silk showed the highest K/S value that indicated the strongest color intensity and the highest dye uptake.

The dyeing behaviors of berberine chloride, palmatine chloride hydrate, and Phellodendron bark extract on silk fabric were investigated to evaluate palmatine as another chromophoric substance of Phellodendron bark. The dyeing conditions were composed of combinations of pH (3, 5, 7, 9), temperature (10, 30, 55, $80^{\circ}C$), and time (10, 30, 60 min). The results indicate that palmatine was comparable to berberine in the dyeing behaviors tested for this study and the results were statistically significant. The dye exhaustion and dye uptake of palmatine-CH were slightly lower than berberine-C, which however were not statistically significant. Similar to berberine-C, palmatine-CH favored a pH 7 condition for both dye exhaustion and dye uptake. However, palmatine-CH favors a higher dyeing temperature and longer dyeing time than berberine-C for superior dyeing results.

항생제 내성균들의 등장으로 새로운 항생제의 개발이 요구되고 있으나 항생제의 개발은 많은 시간과 인력과 개발비를 필요로 한다. 이 문제를 해결하기 위한 방법의 하나로 전통적으로 감염질환의 치료에 사용되어온 식물인 황금과 황백 추출물의 methicillin-resistant Staphylococcus aureus(MRSA)에 대한 항균활성 보유 여부를 조사하였다. 황금의 메탄올 추출물은 MRSA와 Candida에 대하여 높은 항균 활성을 나타내었으며 황백 추출물보다 활성이 높아 앞으로 새로운 항균제로의 개발 및 사용 가능성이 있을 것으로 보여진다.

Indigotin, indirubin, berberine, palmatine, alizarin, and purpurin are major pigments of indigo plant, Phellodendron bark, and madder. The six pigments were examined using the HPLC-DAD-MS instrument for the purpose of the simultaneous detection of the pigments in a single sample run. The HPLC-DAD-MS method examined the individual pigment solutions in DMSO, a solution containing 6 pigments, and the DMSO extract of the silk dyed with a dye solution of 5 pigments excluding indirubin. The retention times of the HPLC chromatograms, ${\lambda}_{max}$ of the uv-vis absorption bands in the DAD analyses, and the molecular ions detected for the compound peaks in the MSD analyses were consistent throughout the analyses of individual pigment solutions, mixed pigment solutions, and dye extracted from silk dyeing. The developed instrumental method of the simultaneous detection of six pigments can identify dye in an exhumed textile if the textile is dyed using any one (or multiple) pigments of indigo, Phellodendron bark, or madder plant.

Phellodendri Cortex, phellodendron bark, has been used as a stomachic for intestinal function control and as an antimicro and anti-inflammatory agent. In this phytochemical study, eight compounds, berberine (1), palmatine (2), syringin (3), (+)-syringaresinol di-O-${\beta}$-D-glucopyranoside (4), salvadoraside (5), citrusin B (6), osmanthuside H (7), and kelampayoside A (8), were isolated from the bark of Phellodendron amurense. Their structures were elucidated by comparing spectroscopic data with reported values. Compounds 1 - 8 were evaluated for cytotoxic activity against HL-60 human promyelocytic leukemia cells in vitro. Among them, compounds 1 and 2 reduced the viability of HL-60 cells significantly, with $IC_{50}$ values of 26.0 and $18.5{\mu}M$, respectively.

In this study, as one of the eco-friendly dyeing methods, indigo, Phellodendron amurense and Caeasapinia sappan were complexed dyed on cotton fabric. For complexed dyeing, the cotton that was pre-dyed 5 times with indigo was dyed 1 ~ 2 times repeatedly with Phellodendron amurense and Caeasapinia sappan. Then the color, tensile strength, density, and color fastness of complexed dyed sample were analyzed and the following analysis results could be obtained. As a result of color difference measurement, the L* value was 22.7 in the sample in which the cotton was dyed 5 times and then the Phellodendron amurense was dyed 1 time, and the K/S value was 15 or higher in all samples. As a result of measuring the strength, cotton fabrics tended to have a slight decrease in tensile strength when complexed dyeing. As a result of measuring the density, the density decreased by 15 ~ 20% in all samples at the warp and increased by 20 ~ 30% in the weft due to the complexed dyeing of cotton fabric. Moreover, the fastness to washing and drycleaning showed good results of 2 ~ 3 or higher, and the light fastness was 4 or higher.

The purpose of this research was to revive the bathochromic effects of wool fabrics by using natural dyestuffs with minimum heavy metallic mordants. The natural dyestuffs used in this research were the indigo plant, Phellodendron amurense, and Caesalpinia sappan. Sample no. 1 was pre-dyed five times with indigo. Sample no. 2 was pre-dyed five times with indigo and then once dyed with Phellodendron amurense. Following the same method as sample no. 2 with an additional Phellodendron, Sample no. 3 consisted of a pre-dye five times with indigo and twice with Phellodendron amurense. Sample no. 4 was pre-dyed six times with indigo and then once dyed with Caesalpinia sappan. Sample no. 5 followed the same method as no. 4 with an additional dye of Caesalpinia sappan. Sample no. 6 was pre-dyed five times with indigo and then once dyed with Phellodendron amurense and once dyed with Caesalpinia sappan. The results were as follows: first, all samples showed deeper colors. Second, according to the results of the surface K/S measurement, the surface K/S of wool fabrics was >20. Third, the results of lightfastness measurement showed superiority over grade 4 in samples no. 1, 2, 3, 5, and 6. However, sample no. 4 was grade 3. In the colorfastness to washing measurement, sample no. 2 showed greater superiority than grade 3-4, while samples no. 1 and 3 were grade 3. In addition, the colorfastness to dry cleaning for all samples was satisfactory or excellent by more than grade 3.

This experiment was carrie out to investigate the amount of essential of leaves and fruits of Magnolia sieboldii, Magnolia hypoleuca, Evodia danillii male and female, Phellodendron amurense male and female and Zanthoxylum schinifolium male and emale by Karlsrube set on August, August, September and October in 1994. Essential oil yield was highest in the fruits of Zanthoxylum schinifollium leaves on Augus the amount of essential oil of Magnolia sieboldii and Magnolia hypoleuca leaves was more than the one of Evodia danillii, Phellodendron amurense and Zanthoxylum schnifolium leaves. The amount of essential oil were not diferent between male and female leaves.
