The combined new phytoformula (CAS), a mixture (5 : 3 : 2, w/w/w) of the ethanol extracts of the roots of C. officinalis and A. japonica, and the n-butanol fraction of the S. subprostrata strongly inhibited arthritic severity score as well as IL-6 production in serum of collagen-induced arthritic mice. Histological observation also indicated that the CAS-treated group showed less breakdown of joint cartilage of the collagen-treated mice. In contrast, C. officinalis alone or a combination of A. japonica and S. subprostrata did not show significant inhibitory action on the same animal model. Thus, it is thought that CAS possesses a synergistic inhibitory action on arthritic condition. All these results strongly suggest that CAS may be a potential anti-arthritic agent.

Objectives : A morphological classification among Achyranthes japonica Nakai (produced in Korea), A. bidentata Blume (imported from China), and Cyathula officinalis Kuan (used in China exclusively) was made through microscopic observation. Method : The slice of the tested material made by paraffin section technique was colored with Safranine Malachite Green contrast methods, and then observed and photographed by olymphus-BHT. Result : 1. Korean A. japonica Nakai has slim roots, whose diameter is $1{\sim}5\;mm$. 1) Most of its intersection is stele, which includes a lot of vascular bundles. The inside of vascular bundles shows the arrangement of $2{\sim}4$ cycles, the innermost wheel of which is divided into two parts. 2) Parts of parenchymatous cell include Crystal sand of calcium oxalate. 2. The diameter of the roots of Chinese A. bidentata Blume is $0.4{\sim}1\;cm$. 1) The xylem in the vascular bundle in the middle of its intersection is rather big, around which the inner parts of the vascular bundles are arranged in the shape of $2{\sim}4$ cycles around. The most outside part of it is small, and the middle part is gathered into $2{\sim}3$ groups. 2) Parts of parenchymatous cells include Crystal sand of calcium oxalate. 3. The roots of Chinese C. officinalis Kuan is thick, whose diameter is $0.5{\sim}3\;cm$. 1) Vascular bundle of its intersection is spotted, arranged in the shape of $4{\sim}11$ concentric circles, whose center is divided into $2{\sim}9$ groups. 2) Parenchymatous cells include crystal sand and square crystal of calcium oxalate. Conclusion : It is concluded that Achyranthes japonica Nakai, A. bidentata Blume, and C. officinalis Kuan have different shapes in both external forms and internal intersections, so that they can be easily distinguished from one another through microscopic observation.

Objectives : This study was performed to investigate the discriminative criteria of 6 kinds of Achyranthis Radix by HPLC/DAD. Methods : 20-hydroxyecdysone is isolated by silica gel column chromatography ($CHCl_3$:MeOH, 7:1-1:1 v/v) and identified by nuclear magnetic resonance, A high-performance liquid chromatographic method with diode array detection was used to identify 20-hydroxyecdysone in A. japonica. The analysis was performed using $C_{18}$ column with isocratic elution consisted of 18% acetonitrile and 82% water and the detection was carried out by DAD at 254 nm. 6 kinds of Achyranthis Radix from different locations were extracted in MeOH. Each extracts was analyzed by HPLC in same condition as used in analysis of 20-hydroxyecdysone. The identities of each extracts were determined by comparing the retention time and UV spectrum with that of reference compound. Results : 1. A. japonica and A. bidentata showed the similar patterns of HPLC chromatogram and 20-hydroxycedysone was present in both of them because the peaks having the same retention time and UV spectrum as 20-hydroxyecdysone were shown in the HPLC chromatograms of A. japonica and A. bidentata 2. Cyathula officinalis and C. capitata showed the similar patterns of HPLC chromatogram. The peak having the same retention time and UV spectrum as 20-hydroxyecdysone was shown in the HPLC chromatogram of C. capitata but not shown in the HPLC chromatogram of C. officinalis. 3. Two species of medicinal drugs from Sacheon province showed similar patterns of HPLC chromatogram. Achyranthis Radix from Sacheon(wild) did not have 20-hydroxycedysone but Achyranthis Radix from Sacheon(cultivated) showed the peak having the same retention time as 20-hydroxyecdysone but UV spectrum of the peak was different from that of 20-hydroxyecdysone. Conclusions : These results suggested that 20-hydroxyecdysone could be the discriminative criteria for Achyranthis Radix contain 20-hydroxyecdysone though they belong to different genus and species. And the patterns of HPLC chromatogram also could be the discriminative criteria as the different species of Achyranthis Radix belonging to the same genus showed similar patterns of HPLC chromatogram.
