Cyperus rotundus L. (Cyperaceae) has been used as an analgesic and antiiflammatory agent and in the treatment of menstrual disorder in folk remedies. Cyperi Rhizomata, processed and unprocessed, were extracted with methanol and fractionated with petroleum ether, chloroform. Butanol, water. The effect of unprocessed Cyperi Rhizoma and processed Cyperi Rhizoma on $CCl_4$ induced lipid peroxidation and hepatotoxity have been tested in rats. BuOH. Water fractions of unprocessed Cyperi Rhizome enhanced the inhibition of antilipid peroxidative effects in liver lipid. In chemical parameters obtained from serum analysis. Butanol fraction of unprocessed Cyperi Rhizoma showed significant decrease in hepatotoxicity. In result, unprocessed Cyperi rhizoma has significant antilipid peroxidative effect and hepatoprotective activity.

Arginase competitively inhibits nitric oxide synthase (NOS) via use of the common substrate L-arginine. Arginase II has recently reported as a novel therapeutic target for the treatment of cardiovascular diseases such as atherosclerosis. In our experiment, the EtOH extracts of four-hundreds extracts drugs were investigated for the arginase inhibitory activity. Among them, four extracts exhibited over 50% inhibition of arginase II activity compared to control at a concentration of 150${\mu}g/ml$. In particular, the seed of Arctium lappa, gum-resin of Boswellia carterii, aerial part of Artemisia apiacea and rhizome of Cyperus rotundus inhibited arginase II activity, with $IC_{50}$ values of 118.4, 135.4, 123.9 and 86.7${\mu}g/ml$, respectively. In addition, four plant extracts showed less than 20% inhibition of arginase I activity at 150${\mu}g/ml$. These plants might be the potential candidate materials in the development of the novel atherosclerosis drug.

Cyperi Rhizoma (CR), the rhizome of Cyperus rotundus L., exhibits neuroprotective effects in in vitro and in vivo models of neuronal diseases. Nevertheless, no study has aimed at finding the neuroactive constituent(s) of CR. In this study, we identified active compounds in a CR extract (CRE) using bioactivity-guided fractionation. We first compared the anti-oxidative and neuroprotective activities of four fractions and the CRE total extract. Only the ethyl acetate (EA) fraction revealed strong activity, and further isolation from the bioactive EA fraction yielded nine constituents: scirpusin A (1), scirpusin B (2), luteolin (3), 6'-acetyl-3,6-diferuloylsucrose (4), 4',6' diacetyl-3,6-diferuloylsucrose (5), p-coumaric acid (6), ferulic acid (7), pinellic acid (8), and fulgidic acid (9). The activities of constituents 1-9 were assessed in terms of anti-oxidative, neuroprotective, anti-inflammatory, and anti-amyloid-${\beta}$ activities. Constituents 1, 2, and 3 exhibited strong activities; constituents 1 and 2 were characterized for the first time in this study. These results provide evidence for the value of CRE as a source of multi-functional neuroprotectants, and constituents 1 and 2 may represent new candidates for further development in therapeutic use against neurodegenerative diseases.

Objectives: Samul-tang and Rhizome of Cyperus rotundus L. have been frequently used in gynecologic disease. The purpose of the present study is to explore the behavioral and neurobiological effects of Samul-tanggahyangbuja (SGH) on ovariectomized rats and to form a basis for clinical treatment. Methods: Ovariectomized rats were repeatedly stressed for over 2 weeks. After orally medicated with SGH (200 or 400 mg/kg/day), the anxiety response was tested using the Elevated Plus Maze (EPM) in rats. The serum levels of estradiol and IL-4, and immunohistochemical changes of IL-4 in the Locus coeruleus (LC) and Paraventricular Nucleus (PVN) were measured. Results: 1. In the EPM, SGH 400 mg significantly increased time spent on the open arms and decreased time spent on the closed arms, compared with the control group (p<0.05). 2. SGH tended to increase numbers of crossings in the open and closed arms in the EPM. However, it did not reach statistical significance. 3. SGH significantly increased the serum levels of estradiol compared with the control group (p<0.05). 4. SGH 400 mg significantly increased the serum levels of IL-4 compared with the control group (p<0.05). 5. IL-4 immunoreactivity was reduced in the control group compared with the normal group (p<0.05). However, SGH groups (200 and 400 mg) did not produce any significant effects on levels of IL-4 in the LC and PVN. Conclusions: These results suggest that SGH possesses the anti-depressant and immuno-modulatory effects on ovariectomized rats.

Objectives: This study was performed to review the research trends regarding the treatment of Postpartum Depression (P.P.D) in the Traditional Chinese Medicine (TCM). Methods: We searched articles in CNKI (China National Knowledge Infrastructure) from 2004 to 2013. Search key words were "产后抑郁症", "Postpartum Depression", and we selected 27 studies except for non-clinical studies, insufficient number of studies, unrelated studies and tests on animals. Results: We selected 27 articles with following results: 1) One study of Jadad Quality Assessment Scale score showed 3 points, 4 studies showed 2 points and 22 studies showed less than 1 point. Overall, the quality of the studies was low. 2) DSM - IV was frequently used as a diagnostic criteria and HAMD was mostly used as evaluation criteria. Diagnostic criteria and evaluation criteria were the same in HAMD and EPDS. 3) In TCM, there are various ways, such as herbal medicine, acupuncture, electro acupuncture, auricular acupuncture and/or massage to treat the postpartum depression. 4) The roots of Bupleurum falcatum Linne, Glycyrrhiza uralensis Fisch, Angelica gigas Nakai and Paeonia lactiflora Pall, the rhizome of Atractylodis macrocephala Koidz, the semen of Zizyphus jujuba Mill, the radix of Curcuma aromatica Salisb, the sclerotium of Poria cocos Wolf and the rhizomas of Cyperus rotundus L and of Cnidium officinale Makino are mainly used in the herbal medicine. BaekHoi (GV20) and Yindang (Ex-HN3) are mainly used in acupuncture points. 5) Most of the studies showed effective results. Some of the results were similar to those of the control groups which were cured by western medicine. Other results were better than those of control groups. Conclusions: Research on postpartum depression has been actively conducted in TCM and all studies showed effective results in the study group patients. Therefore, with this study, we hope to activate more clinical research on the treatment of patients in Korean traditional medicine.

Objectives: The purpose of the present study is to investigate anti-depressive effects of Samul-tanggahyangbuja (SGH) on ovariectomized and chronic mild stress (CMS) induced rats. Methods: Ovariectomized rats were exposed to CMS for 4 weeks. Changes of depression behavior were tested by using sucrose intake test (SIT), elevated plus maze (EPM), forced swimming test (FST) and Morris water maze test (MWMT) in rats until being orally medicated with SGH (100 or 400 mg/kg/day). In addition, the serum levels of corticosterone (CORT), IL-4, IL-$1{\beta}$ and changes of 5-HT in the brain were measured. Results: 1. SGH 400 mg/kg treated group (SGH 400) significantly increased amount of sucrose intake compared with the control group (p<0.05). 2. SGH 100 mg/kg treated group (SGH 100) and SGH 400 significantly increased the time spent in the open arms of the EPM compared with the control group (p<0.01). SGH 400 also significantly increased the number of crossing of the open and closed arms compared with the control group (p<0.05). 3. SGH significantly shortened the immobility time in FST compared with the control group (SGH 100 p<0.05, SGH 400 p<0.01). 4. SGH significantly increased performance of acquisition trials compared with the control group (p<0.05, on day 4, 5 of SGH 100 and 400). SGH 400 also significantly increased performance of retention trials compared with the control group (p<0.05). 5. The serum levels of corticosterone and IL-4 were not significantly different among the groups. There were no changes on the serum levels of corticosterone, IL-$1{\beta}$ and IL-4 after administration with SGH. 6. SGH 400 significantly increased the level of 5-HT in the hippocampus compared with the control group (p<0.05). SGH significantly increased the levels of 5-HT in the hypothalamus compared with the control group (SGH 100 p<0.05, SGH 400 p<0.01). Conclusions: These results suggest that SGH has the anti-depressive effect on ovariectomized rat and affect 5-HT system rather than hypothalamic-pituitary-adrenal (HPA) axis and immune system.
