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.

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.

'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.

Two isoquinolines and one quinolone were isolated from the stem bark of Pellodendron amurense Rupr. (Rutaceae). Two isoquinolines were elucidated as thalifoline (2) and pharmacological active berberine (3) has been blocking the release of $Ca^{2+}$ from internal stores. One quinolone was identified as N-methylatanine (1). This is the first report on the isolation of N-methylatanine (1) and thalifoline (2) from this plant.

Three limonoids and two phenolics were isolated from stem bark of Pellodendron amurense Rupr. (Rutaceae) and were defined clearly as calodendrolide (1), obacunone (2), limonin (3), methyl 4-hydroxybenzoate (4), and syringin (5) based on NMR spectroscopy results obtained with the aid of X-ray crystallographic analysis. This is the first report on the isolation of calodendrolide (1) from this plant.

In Traditional Oriental Medicine, the drug treatment has been explained by the thoery of "Si Qi Wu Wei(四氣五味)". Among them, Xin(辛) has effect of Sheng(升), San(散), Xing(行), and Ku(苦) has effect of Jiang xia(降下), Zao shi(燥濕), Jian yin(堅陰). The study on the medical action of Asari Radix shows that "Xin ke run zao(辛可潤燥)" was derived from Sheng(升), San(散), Xing(行) efficacy of sour. And the study on the medical action of Phellodendron Bark, Anemarrhenae Rhizoma shows that "Ku ke run zao(苦可潤燥)" was derived from Xie(泄) efficacy of bitter.

This research investigated the dyeing behavior of palmatine (a major coloring compound of Phellodendron bark in addition to berberine) using mercerization (M), tannic acid (T), mercerization-tannic acid (MT), and tannic acid -mercerization (TM) pretreatments. Mercerization was conducted using $20^{\circ}C$ of 20% NaOH for 5 minutes. Tannic acid treatment was conducted using 15% o.w.f. solution of tannic acid at $60^{\circ}C$ for 30 minutes and fixed with potassium antimonyl tartrate trihydrate. Dyeing was conducted using 1% o.w.f. palmatine chloride hydrate with 1:100 liquor ratio at $10-95^{\circ}C$ for 10-60 minutes in a dyebath of pH 3-9. MT method resulted in the highest dye uptake and was two times higher than the average dye uptake of T method. MT method provided the best result when the dyeing temperature was $80^{\circ}C$ or $95^{\circ}C$ and the dyeing time was 60 minutes. The pH of the dyebath had less effect on the dye uptake but a pH higher than 5 provided better results. The study confirmed that palmatine is a major coloring compound of Phellodendron bark and that the MT method can be used as a successful cotton dyeing method.
