  • Objectives : Cynanchum wilfordii(Asclepiadaceae) has been traditionally used as a tonic, the prevention and treatment of various geriatric diseases in Korea. Acetophenone derivatives from C. wilfordii showed neuroprotective activity. In this study, two acetophenones were isolated and quantitative determination of acetophenones from C. wilfordii has been developed for quality stand. Methods : Three acetophenone derivatives were isolated from methanol extract of C. willfordii by the chromatographic separation. Their structures were identified as cynandione A, 2,5-dihydroxy acetophenone and cynanchone A on the basis of spectral data(MS, $^1H-NMR$, $^{13}C-NMR$) and chemical analysis. HPLC analysis was performed to determine the contents of cynandione A and 2,5-dihydroxyacetophenone in C. wilfordii. Results : According to the results, the contents of cynandione A and 2,5- dihydroxyacetophenone were 0.274%, 0.035% by HPLC, respectively. Conclusions : In these results, we have determined the contents of cynandione A and 2,5-dihydroxyacetophenone in Cynanchum wilfordii, respectively. We hope that this study will contribute to the standardization and quality control of herbal medicine.

  • The purpose of this study was designed to observe the effects of the feeding Cynanchum wilfordii extract on the improvement of the blood glucose, lipid components in the serum of dietary hyperlipidemic and streptozotocin(STZ) -induced diabetic rats(S.D. strain, ♂) fed the experimental diets for 5 weeks. Concentrations of total cholesterol, atherosclerotic index, LDL, LDL-Cholesterol, free-cholesterol. cholesteryl ester, TG, PL and blood glucose in serum were significantly higher in the cholesterol administration groups((group 2(cholesterol+water), 4(cholesterol+Cynanchum WIlfordii 3.5g% extract)) than those in the control group (group1 , basal diet+water). But the concentrations of total cholesterol. atherosclerotic index, LDL, LDL- cholesterol. free-cholesterol, cholesteryl ester, TG, PL and blood glucose in serum were remakably lower in the group 4 than those in the group 2. In the STZ(55mg/kg B.W.)-induced diabetic groups((group 3(STZ, IP.)+water), 5(STZ(IP.)+Cynanchum WIlfordii 3.5g% extract? the serum total cholesterol, atherosclerotic index, LDL, LDL-cholesterol, free-cholesterol. cholesteryl ester, TG, PL and blood glucose concentrations actions were rather lower in the group 5 than those in the group 3. In the ratio of HDL -cholesterol concentration to total cholesterol and HDL-cholesterol concentration, Cynanchum wilfordii extract administration groups were higher percentage than III the groups 2 and 3. The activities of aspartate aminotransferase(AST), alanine aminotransferase(ALT), alkaline phosphatase (ALP) and lactate dehydrogenase(LDH) in serum were rather lower in the Cynanchum wllfordii extract administration groups (group 4,5) than in the cholesterol diet group(group 2) and STZ-induced diabetic group (group 3). From the above research, the physiological activity substances in Cynanchum wllfordii were effective on the improvement of the blood glucose, lipid compositions in serum of dietary hyperlipidemic and STZ-induced diabetic rats. And particularly, physiological activity substance in Cynanchum wilfordii was more effective therapeutic regimen for the control of metabolic derangements in adult disease.

  • Background: Dried tuberous roots of Cynanchum wilfordii are known to relieve menopause symptoms. However, the dried roots of C. wilfordii are morphologically similar to those of C. auriculatum, which makes it difficult to distinguish when used as a medicine. Various comparative studies have focused on chemical or molecular analysis of these roots. However, the differences between the two species at the cytogenetic level based on chromosome structure and composition remain to be elucidated. Methods and Results: For chromosome slides, the roots were fixed in 8-hydroxyquinoline, digested with enzyme mixture, and spread on slides. 5S and 45S rDNA were used as cytogenetic markers for the analysis of nuclear genomes by FISH. The chromosome number of the two species was 2n = 22, with a relatively short length, 1.13 ㎛ - 4.24 ㎛ and 1.00 ㎛ - 3.42 ㎛ with respect to each other. Both species represent one pair of 5S and 45S rDNA signal on chromosome 1, at the proximal region and peri-centromeric region, respectively. Conclusions: These preliminary cytogenetic data using FISH in C. wilfordii and C. auriculatum could be valuable for the comprehension of Cynanchum genome history.

  • Definitive identification of original plant species is important for standardizing herbal medicine. The herbal medicines Cynanchi Wilfordii Radix (Baekshuoh in Korean and Beishuwu in Chinese) and Polygoni Multiflori Radix (Hashuoh in Korean and Heshuwu in Chinese) are often misidentified in the Korean herbal market due to morphological similarities and similar names. Therefore, we developed a reliable molecular marker for the identification of Cynanchi Wilfordii Radix and Polygoni Multiflori Radix. We used random amplified polymorphic DNA (RAPD) analysis of three plant species, Polygoni multiflorum, Cynanchum wilfordii, and Cynanchum auriculatum, to obtain several species-specific RAPD amplicons. From nucleotide sequences of these RAPD amplicons, we developed six sequence characterized amplification region (SCAR) markers for distinguishing Polygoni Multiflori Radix and Cynanchi Wilfordii Radix. Furthermore, we established SCAR markers for the simultaneous discrimination of the three species within a single reaction by using multiplex-PCR. These SCAR markers can be used for efficient and rapid authentication of these closely related species, and will be useful for preventing the distribution of adulterants.

  • These studies were conducted to discriminate Cynanchum wilfordii, C. auriculatum, Metaplexis japonica, and Polygonum multiflorum by morphological characters. Cynanchum wilfordii, C. auriculatum, and Metaplexis japonica(Asclepiadaceae) were easily distinguished from Polygonum multiflorum by twining stem to the left, producing opposite leaves, having laticiferous stems and leaves at cutting cross-sectionally, and lacking lignification of the stem. Four species had different morphological characters of flower. Comparing four species to fruit type, three species of Asclepiadaceae had follicle, while Polygonum multiflorum had achene with three wings. Follicle shape was lanceolate, narrowly lanceolate, and widely lanceolate in C. wilfordii, C. auriculatum, and Metaplexis japonica, respectively. Whereas seed color of four species was dark brown similarly, seed shape and 1,000 seed weight were useful characters to discrimate between three species of Asclepiadaceae and Polygonum multiflorum. Shape and color of root were thickened and yellowish brown in C. wilfordii and C. auriculatum. They were thin and long and white in Metaplexis japonica, and fusiform and reddish brown in Polygonum multiflorum. They would be useful characters to distinguish Cynanchum spp., Metaplexis japonica, and Polygonum multiflorum, however, impossible characters to discriminate between C. wilfordii and C. auriculatum.

  • The purpose of this study was to investigate the effects of the ethanol extract of Cynanchum wilfordii (ECW) on the blood lipid profile of hypercholesterolemic rats. Thirty 7-week-old male Sprague-Dawley rats were allowed free access to either a normal diet (AIN-93 diet), or 1% high-cholesterol diet with or without 0.5% or 1% ECW for 5 weeks. After sacrifice, the rat serum lipid profile was analyzed. The diets containing ECW decreased body weight gains compared to the normal diet. Serum HDL-cholesterol levels of ECW-fed groups were significantly increased in the hypercholesterolemic groups and normal groups (P<0.05). When 1% ECW was fed to the normal group, total cholesterol level was increased. Moreover, treatment of ECW in hypercholesterolemic groups yielded a dose-dependent and highly significant decrease in the atherogenic index as compared to the control. These results suggest that intake of Cynanchum wilfordii may help reduce the risks of hypercholesterolemia by increasing blood HDL-cholesterol and lowering the atherogenic index.

  • Menstrual problem (premenstrual syndrome (PMS) and dysmenorrhea) is a common gynecological complaints among women in reproductive age. The aim of this study was to compare the effects of isoflavone and Cynanchum wilfordii for improvement of premenstrual syndrome, dysmenorrhea. Subjects were 30 college women in Busan, divided into three groups (CG; control group, n=10; IS group; isoflavone supplement group, n=10; CS group; Cynanchum wilfordii supplement group, n=10). They showed 5.0 or higher for menstrual pain when tested by the VAS. IS group was allocated a isoflavone pill (500 mg/day) for 8 weeks, and CS group was allocated a Cynanchum wilfordii pill (6 g/day) for 8 weeks. We administered a menstrual distress questionnaire (MDQ), and visual analogue scale(VAS). There were no differences among the three groups in general characteristics, nutrients intake, MDQ, or VAS. In the CG group, there were no differences in MDQ, or VAS after 8 weeks. In the IS group, negative emotions, behavioral changes, concentration, pain, autonomic nervous system response, water retention, and skin changes significantly improved (P<0.05). In the CS group, negative emotions, pain, autonomic nervous system response, and water retention significantly decreased after 8 weeks (P<0.05). Changes in negative emotion, pain, autonomic nervous system response, water retention, skin changes significantly improved in the CS group compared to the control group (P<0.05). VAS significantly decreased in the IS and CS groups (P<0.05). The decrease in VAS differed among three groups, with the CS group showing a larger decrease than the control group and IS group (P<0.001).
