In this research, the curly dock was used in the process of dyeing for fabrics of the inner wear & the patient wear. Since the curly dock has a pharmacological effect on dermatosis, this study focused on the variety of color and functions of the inner wear fabrics & patient wear fabrics to make the best use of the pharmacological effect of curly dock. With regards to giving a variety of colors and functions in the inner wear, patient wear fabrics, the curly dock dye was used in each treatment conditions on the cotton & silk fabrics. After dyeing, the dyeability, color change, light fastness, washing fastness, perspiration fastness, antibiosis, far infrared emissivity and emission power were evaluated. The evaluation results are as follows; The dyeablity increased from repeated dyeing and, by using the mordant, variety of colors such as skin, mustard, greyish-brown and dark earth colors were conformed to the naked eye. Fe mordant was better than Al on the lightfastness and the washing fastness. The repeated dyeing was found out to have less effect on neither lightfastness nor washing fastness. Both silk and cotton fabrics were graded $3{\sim}4$, since their degree of degradation appeared to be the same in alkali perspiration and acidic perspiration. In the case of silk fabrics mordanted by Al, the rate of declining in both Staphylococcus aureus ATCC 6538 and Klebsiella pneumonia ATCC 4352 were 99.9%. In addition, the antibiosis was enhanced when the mordant was used. The far infrared was 86.6% of emissivity, $3.34{\times}10^2\;W/m^2{\cdot}{\mu}m$ emission power.

This study investigated the anti-inflammatory effects of processed (Beopje) curly dock (Rumex crispus L.) in LPS (lipopolysaccharide)-stimulated murine RAW 264.7 cells. The experimental group was classified into five groups : LPS no treatment, CD (curly dock), CD-B (CD processed through Beopje), LPS, LPS+CD-B (LPS+CD processed through Beopje) and LPS+CD (LPS+CD). Treatment of the Raw 264.7 cell lines using LPS led to a significant increase in NO production, pro-inflammatory cytokines ($TNF-{\alpha}$, IL-6 and $IL-1{\beta}$), and inflammation related genes (COX-2 and iNOS). Investigation of the inhibitory effects of CD and processed CD on NO production and expression of iNOS and COX-2 was done in LPS-induced RAW 264.7 cells. There was significant inhibition of NO production by LPS+CD and LPS+CD-B in a dose-dependent manner (p<0.05). Particularly, LPS+CD-B exhibited reduced mRNA expression of iNOS and COX-2 and NO production as compared to LPS+CD in Raw 264.7 cell lines (p<0.05). These results may explain some known biological activities of curly dock including the anti-inflammatory effects. CD-B in particular exhibited the highest anti-inflammatory effects of inhibiting production of NO, through the regulation of inflammatory related genes and pro-inflammatory cytokines. These results of Beopje processing might help decrease the anti-biological effects and increase several active substances of curly dock.

The objective of this study was to isolate a herbicidally active compound from curly dock (Rumex crispus), a native weed in Korea and to identify its' chemistry. The $GR_{50}$ value of methanol extracts which is determined by a seed bioassay using rapeseed (Brassica napus) seedlings was $935\;{\mu}g\;g^{-1}$. Activity-directed isolation of ethylacetate extract led to the isolation of ECDA fraction with $GR_{50}$ value $53\;{\mu}g\;g^{-1}$. Based on data of GC-MS, $^1H$-NMR and $^{13}C$-NMR, the chemical structure of ECDA was determined as 2H-furo[2,3-H]-[1]-benzopyran-2-one which is known as angelicin. The $GR_{50}$ values of angelicin to barnyardgrass (Echinochloa crus-galli), southern crabgrass (Digitaria ciliaris), and indian jointvetch (Aeschynomene indica) were 426, 66 and $216\;{\mu}g\;g^{-1}$, respectively. Our results suggest that angelicin could be used as a lead compound for the development of new herbicides.
