Background: The study aimed to obtain data on the effects of cultivation and soil reduction of green manure crop on the quantity and quality of organically cultivated Cynanchum wilfordii Hemsley. Methods and Results: The experiment comprised four treatments: control, hairy vetch, barley, and hairy vetch + barley (3 : 2). The plant height in the hairy vetch treatment (86.3 cm) was significantly different from that in the other treatments, whereas the stem diameter leaf area, and special product analysis division (SPAD) value did not differ across the treatments. The largest soil reduction of green manure crop was recorded in the barley treatment (440 kg/10 a), whereas the smallest was recorded in the single treatment with hairy vetch (80 kg/10 a). The hairy vetch + barley (60 : 40) treatment showed 63% more soil microorganisms than control. Radical scavenging activity estimation revealed that the total polyphenol content was highest (1,740 mg/kg), and the 2,2-diphenyl-1-picrylhydrazyl (DPPH) was 92.6% in the barley treatment. The 2,2′-azino-bis-(3-ethylbenzothiazoline-6-sulfonic acid) (ABTS) activation was highest in the control (51.1%), and the root yield was the highest in the barley treatment (310 kg/10 a). Conclusions: The root yield, total polyphenol content, and antioxidant activity of Cynanchum wilfordii (Maxim.) Hemsley increased in presence of the green manure crop barley.

This study was performed to select the soil covering materials for winter safety of Cynanchum wilfordii Hemsley and to investigate the effect on the growth after overwinter. Soil covering materials such as vinyl, rice straw, lagging cover, vinyl+lagging cover, and non-covering were investigated how effect on overwintering rate, growth and yield of Cynanchum wilfordii Hemsley. In changes of soil temperature according to the soil covering materials, non-covering treatment was recorded the highest to $26.7^{\circ}C$, and lagging cover and rice straw showed little change of soil temperature with 9.2 and $9.3^{\circ}C$, respectively. Regrowth rates of early growth after overwinter were lowered in the order as rice straw > vinly+lagging cover > lagging cover > vinyl > non-covering. From the above-ground growth by soil covering materials, vine length showed similar growth in all treatments except vinyl covering and stem diameter exhibited the thicker pattern in vinyl and lagging cover, and there was no significant difference among treatments in number of branch. Flowering period is recorded July 30 in all treatments and ripening period is October 16. Yield of seed production is showed the best in vinyl+lagging cover with $25g/m^2$. Root weight and root length for subterranean growth showed no significant differences among all treatments. Yield is produced the highest in vinyl+lagging cover with 433kg/10a and the next to lagging cover with 431kg/10a. In comparison with incomes, lagging cover earned to 9,882 thousand won/10a, showed the effect on income enlargement to 21%, compare to that of the non-covering.

Hormone replacement therapy (HRT) consists of highly effective prescription medications for treating menopausal symptoms; however, these agents have exhibited side effects including the risk of estrogen-induced carcinogenesis. Therefore, interest in phytotherapy-based materials as a natural source of alternatives to estrogen therapy has increased. However, some of these herbal medicines have been reported to increase the risk of estrogen-induced cancer. Herbal formulations composed of a combination of Cynanchum wilfordii Hemsley (CW), Phlomis umbrosa Turczaninow (PU), and Angelica gigas Nakai (AG) extracts (CPAE) have been used for treating menopausal symptoms. Therefore, in this study, we aimed to examine the safety of CPAE by determining its potential adverse estrogenic activity using the Organization for Economic Cooperation and Development (OECD) test guideline 455 (TG455) in a stably transfected transcriptionally activated human estrogen receptor ${\alpha}$ ($hER{\alpha}$)-HeLa9903 cell model. We found that CPAE did not how any estrogenic activity or stimulate promoters containing estrogen response elements in MCF-7 cells. In addition, CPAE showed no significant selective activity against $hER{\alpha}$ and $hER{\beta}$, non-selective activity against the ER, or effects on ER target gene expression. Furthermore, CPAE did not significantly induce MCF-7 cell proliferation and uterine weight increase in ovariectomized rats. These results demonstrate that CPAE can be used as beneficial herbal drug for prevention and therapeutic intervention of estrogen carcinogenesis in menopausal women.

A This study evaluated the antidepressant effects of the herbal mixture CPAE(Cynanchum wilfordii Hemsley, Phlomis umbrosa Turcz, and Angelica gigas Nakai) using several tests, including a test for serotonin 6($5-HT_6$) receptor activity, the forced swimming test(FST), and tests for corticosterone(CORT) and monoamine levels. CPAE showed antagonistic effects on the $5-HT_6$ receptor in a stable $5-HT_6$ receptor-expressing cell line. We subsequently confirmed the antidepressant effects of CPAE in chronic stress model in mice and explored the underlying mechanisms of its action. Specifically, we observed that CPAE treatment significantly reduced immobility time in the FST and effectively restored abnormal levels of CORT in plasma and of monoamines(serotonin, dopamine, and norepinephrine) in hippocampus and prefrontal cortex. These results suggest that CPAE has significant antidepressant effects.

This study was designed to investigate the effects of Angelicae Gigantis and Cynanchum wilfordii Hemsley extract (AAC) on the changes of regional cerebral blood flow (rCBF) and mean arterial blood pressure (MABP) in normal rats, and in the rats with cerebral ischemia induced by middle cerebral artery occlusion, and further to determine the mechanisms. The results were as follows. AAC significantly increased rCBF but significantly decreased MABP in a dose-dependent manner in normal rats. The increase of AAC-induced rCBF was significantly inhibited by pretreatment with methylene blue (0.01 mg/kg, i.p.), an inhibitor of guanylate cyclase, and AAC-induced MABP was decreased by pretreatment with methylene blue. In cerebral ischemics, rCBF was stably improved by AAC (10 mg/kg, i.p.) during the period of cerebral reperfusion, which was contrasted with the findings of rapid and marked increase in the control group. These results suggest that AAC can increase rCBF in the normal state, as well as improve the stability of rCBF in cerebral ischemic state.
