The essential oil of Nardostachys jatamansi (Valerianaceae), which has been used for a long time in aroma therapy, was investigated after inhalation or oral administration for its analgesic effect, anticonvulsant action, hypnotic effect and in vitro inhibitory activity on monoamine oxidase. This fragrance oil showed a significant analgesic effect in the phenylquinone-induced .writhing test, suppressed the convulsion induced by pentylenetetrazole and lengthened the pentobarbital-induced sleeping time in a time-dependent manner after fragrance inhalation or dose-independently by oral administration. Its inhibitory activity on monoamine oxidase was remarkable, showing $49.4\%$ inhibition at a concentration of 5.0 mg/ml. Six new terpenes with seven known compounds were detected by our GC-MS analytical conditions used. As a result, the essential oil fragrance of Nardostachys jatamansi would be clinically useful for a sedative by either inhalation or oral administration.

Nardostachys jatamansi (NJ) belonging to the Valerianaceae family has been used as a remedy for gastrointestinal inflammatory diseases for decades. However, the potential for NJ to ameliorate alcoholic chronic pancreatitis (ACP) is unknown. The aim of this study was to examine the inhibitory effects of NJ on ACP. C57black/6 mice received ethanol injections intraperitoneally for 3 weeks against a background of cerulein-induced acute pancreatitis. During ACP, NJ was ad libitum administrated orally with water. After 3 weeks of treatment, the pancreas was harvested for histological examination. NJ treatment increased the pancreatic acinar cell survival (confirmed by amylase level testing) and reduced collagen deposition and pancreatic stellate cell (PSC) activation. In addition, NJ treatment reduced the activation but not death of PSC. In conclusion, our results suggest that NJ attenuated ACP through the inhibition of PSC activation.

Objectives NJ is being used to treat inflammatory diseases in Korea. In this study, we attempted to evaluate the effects of NJ on atopic dermatitis (AD)-like lesions and mast cell-mediated allergy inflammation in vivo and in vitro. Methods and Results We investigated to ascertain the pharmacological effects of NJ on 2,4-dinitrofluorobenzene (DNFB)-induced allergic reactions under in vivo conditions. Additionally, to find possible explanations for the anti-inflammatory mechanisms of NJ, we evaluated the regulatory effects of NJ on the level of inflammatory mediators in phorbol 12-myristate 13-acetate plus calcium ionophore A23187 (PMACI)-stimulated human mast cells (HMC-1). Conclusions NJ inhibited the production of the inflammatory cytokines (IgE, IL-6, IL-8 and TNF-${\alpha}$) significantly in vivo and in vitro.

Nardostachys jatamansi water extract (NJ) has long been used for the treatment of inflammation-and immune-mediated disorders in the oriental countries. However, its site of action and pharmacological mechanism are not fully investigated. In this study, the authors tried to explore the cytoprotective and anti-inflammatory actions of NJ. First of all, NJ has no harmful effects on viability of neuronal cell line HT22 cells in the dose range of 300 mg/ml. On the contrary, it shows cytoprotective effects on the cells treated with reactive oxygen species H2O2. Probably the cytoprotective effects of NJ might be caused by its ability to induce well known cytoprotective gene hem oxygenase-1 (HO-1). Furthermore, NJ shows inhibitory effects on the expression of inducible nitric oxide synthase (iNOS) and NO production which are known to destroy the integrity of both cells and tissues. It also inhibits potent proinflammatory cytokine tumor necrosis factor-alpha (TNF-a) production. The blocking effects of NJ on cytopathic and proinflammatory actions of LPS might be caused by the induction of cytoprotective and anti-inflammatory genes HO-1 in macrophages cell line RAW 264.7 cells. The results in this study suggest NJ could be used for the amelioration of inflammation which is underlying mechanism responsible for most chronic diseases.

Objectives : Nardostachys jatamansi (NJ) is a medicinal herb that has been reported in various traditional systems of medicine for its use in antispasmodic, a digestive stimulant, skin diseases. Previous studies have already reported that NJ effectively protects against inflammation. However, the active compound in NJ is unknown. Therefore, in the present study, we analyzed effects of a compound, 8α-hydroxy pinoresinol (HP), isolated from NJ against lipopolysaccharide (LPS) induced inflammation in RAW 264.7 cells.Methods : To examine the anti-inflammatory effect of HP against LPS, intraperitoneally pre-treat the HP (100, 200, 500 and 1,000 nM) 1 h prior to LPS challenges. LPS was stimulated with 500 ng/ml in RAW 264.7 cells. To identify the anti-inflammatory effect of HP, we measured inflammatory mediators such as inducible nitric oxide synthase (iNOS) and its derivative nitric oxide (NO), cyclooxygenase-2 (COX-2), prostaglandin E2 (PGE2). Also we evaluated molecular mechanisms including mitogen-activated protein kinases (MAPKs) and nuclear factor-kappaB (NF-κB) activation by western blot.Results : The HP inhibited production of inflammatory mediators, such as iNOS and its derivative NO, COX-2 and PGE2 in LPS- induced inflammationin RAW 264.7 cells. Additionally, HP also inhibited activation of p38 pathway signaling but not extracellularsignal-regulatedkinase (ERK), c-jun NH2-terminal kinase (JNK), and NF-κB.Conclusion : Our results suggest that HP has anti-inflammatory functions through the dephosphorylation of p38 and HP can provide beneficial strategy for prevention and therapy of inflammation.

Purpose: The purpose of this study is to investigate inhibitory effect on the maturation of dendritic cells from aqueous extract from Nardostachys Jatamansi(NJ). Methods: I examined the phenotypic maturation(class II MHC, CD40, CD86), expression of pro-inflammatory cytokine(TNF-$\alpha$, IL-6, IL-12) and endocytosis of FITC-Dextran in the LPS-induced bone marrow-derived dendritic cells(BMDCs) of mice. Furthermore, the Western-blot analysis reveals the mechanism of inhibitory effect. Results: 1. The NJ extract inhibited the phenotypic maturation of BMDCs in a dose-dependent manner. 2. The NJ extract inhibited the LPS induced cytokine production of BMDCs in a dose-dependent manner. 3. The NJ extract enhanced the endocytosis of Dex-FITC in LPS treated DC. 4. The NJ extract inhibited the activation of JNK and p38 phosphorylation, but not ERK phosphorylation of MAPK family and doesn't inhibit Ik-Ba degradation in LPS-stimulated BMDCs. Conclusion: These results suggest that NJ extract is able to attenuate the inflammation and maturation in BMDCs and may inhibit proliferation of T cells. In conclusion, this experiment suggests that NJ extract may be useful in hypersensitivity disease including autoimmune disease.

The purpose of this study is to confirm the antioxidant, black hair, and hair growth effects of the N. jatamansi, O. basilicum, and C. sativus mixed extracts that pharmacological efficacy has been verified. Accordingly, four samples (NOC-1 to-4) produced under different extraction conditions were prepared and the results are as follows. First, all samples showed an increase in antioxidant content in a concentration-dependent manner from the results of antioxidant efficacy. In particular, NOC-4 extracted by steaming and ultrasonic methods showed the highest antioxidant effect among the four samples. As a result of analysis of the amount of melanin production in mouse melanoma cells, NOC-4 with concentration of 500 ㎍/ml showed higher melanin production compared to the control group, so the black hair efficacy was the best. Also, in the hair growth test results, it was found that the hair growth was the best at 0.94 ± 0.10 mm at experimental group orally administered with 500 mg/kg of NOC-4. In addition, as a result of cytotoxicity analysis in mouse melanoma cells, the safety of samples was demonstrated by maintaining cell viability of 95% or more at all concentrations. These results suggest that the steaming and ultrasonic extraction method increased the extraction yield of active ingredients for antioxidant, melanin, and hair generation, thereby affecting physiological activity. Based on these results, if the steaming and ultrasonic extraction methods are applied to the mixed extraction of N. jatamansi, O. basilicum, and C. sativus, it is judged that the practical potential as a natural material for black hair and hair growth agents will increase.

Objectives: This study is to review the effect of Korean medicinal herbs on treatment of polycystic ovary induced rat models reported in domestic & foreign journals. Methods: 7 electronic databases (Pubmed, CNKI, EMBASE, Oasis, RISS, CENTRAL, Koreankt) were searched with term as polycystic ovary, and study reports on polycystic ovary impairment with Korean medicinal herbs. After selecting several studies, the analysis was focused on items reflected in the Rotterdam criteria for diagnosis of polycystic ovary syndrome such as hyperandrogenism (HA), ovarian weight, the number of follicle cysts, estrous cycles, and etc. Results: 15 studies were reviewed. As a polycystic ovary induction material, estradiol valerate (EV) was used in 9 studies, testosterone propionate (TP) in 2 studies and dihydrotestosterone (DHT), dehydroepiandrosterone (DHEA), Poretsky's method and letrozole (LE) was used in rest 4 studies, respectively. Tribulus terrestris (TT), Nardostachys jatamansi (NJ), Lycii cortex (LC), Cinnamomum cassia kees (CCK) and Atractylodis macrocephalae koidz (AMK) produced statistically significant results related to hyperandrogenism. In ovarian weight, Silybum marianum (SM), AMK and Alllium sativum (AS) were statistically significant. In the the number of follicle cysts, SM and TT were statistically significant. In estrous cycles, AMK, NJ, TT and Coix lacryma-jobi (CL) were statistically significant. Conclusions: Based on the diagnosis criteria of Rotterdam, TT, NJ, AMK, SM, AS, and CL produced statistically significant results in rat model.
