Objective : Nelumbo nucifera, its rhizome and semen have been used as a traditional medicine which was studied on antioxidant, hepatoprotective effect, anti-obesity and the others. However, Nelumbinis Flos have not studied. We investigated protective effects on oxidative DNA damage and anti-inflammatory effects of Nelumbinis Flos. Methods : The antioxidant activity was conducted by 1,1-diphenyl-2-picryl hydrazyl (DPPH) radical, 2, 2'-Azino-bis (3-ethylbenzothiazoline-6 sulfonic acid) diammonium salt (ABTS) radical scavenging assay and reducing power assay. Total phenolic content was analyzed. Also, phenolic compounds were detected by HPLC/UV. The inhibitory effect on oxidative DNA damage was determined using ${\Phi}X-174$ RF I plasmid DNA cleavage assay. The anti-inflammatory effect of Nelumbinis Flos was measured by the amount of nitric-oxide (NO) produced and protein levels of iNOS, and COX-2 in LPS induced RAW 264.7 cells. Results : The results of DPPH and ABTS radical scavenging activity at $200{\mu}g/m{\ell}$ of extraction were $97.02{\pm}0.88%$ and $96.42{\pm}0.25%$. Reducing power (fold of L-ascorbic acid as control) was $100.14{\pm}0.31$ at $200{\mu}g/m{\ell}$. Total phenol content was $8.70{\pm}0.02mg/g$. Chlorogenic acid, catechin and epicatechin were found by HPLC. Nelumbinis Flos has inhibitory effect in dose-manner against oxidative DNA damage. In addition, it showed the anti-inflammatory effect by suppression of NO production as well as protein levels of iNOS, and COX-2. Conclusion : This study suggested that Nelumbinis Flos showed potential antioxidant and suppression activities of various factors were related in NO produced. Therefore, Nelumbinis Flos as natural plant resources that may help reduce inflammation and alleviate DNA damage.

This paper deals with the natural occurrence of total aflatoxins ($B_1$, $B_2$, $G_1$, and $G_2$) in commercial herbs for food and medicine. To monitor aflatoxins in commercial herbs for food and medicine not included in the specifications of Food Code, a total of 62 samples of 6 different herbs (Bombycis Corpus, Glycyrrhizae Radix et Rhizoma, Menthae Herba, Nelumbinis Semen, Polygalae Radix, Zizyphi Semen) were collected from Yangnyeong market in Seoul, Korea. The samples were treated by the immunoaffinity column clean-up method and quantified by high performance liquid chromatography (HPLC) with on-line post column photochemical derivatization (PHRED) and fluorescence detection (FLD). The analytical method for aflatoxins was validated by accuracy, precision and detection limits. The method showed recovery values in the 86.9~114.0% range and the values of percent coefficient of variaton (CV%) in the 0.9~9.8% range. The limits of detection (LOD) and quantitation (LOQ) in herb were ranged from 0.020 to $0.363{\mu}g/kg$ and from 0.059 to $1.101{\mu}g/kg$, respectively. Of 62 samples analyzed, 6 semens (the original form of 2 Nelumbinis Semen and 2 Zizyphi Semen, the powder of 1 Nelumbinis Semen and 1 Zizyphi Semen) were aflatoxin positive. Aflatoxins $B_1$ or $B_2$ were detected in all positive samples, and the presence of aflatoxins $G_1$ and $G_2$ were not detected. The amount of total aflatoxins ($B_1$, $B_2$, $G_1$, and $G_2$) in the powder and original form of Nelumbinis Semen and Zizyphi Semen were observed around $ND{\sim}21.8{\mu}g/kg$, which is not regulated presently in Korea. The 56 samples presented levels below the limits of detection and quantitation.

Inhibitory effect of water and ethyl acetate extract of 60 kinds of herbal medicines was investigated on ${\beta}-glucuronidase$. Among water extract of them, Galla Rhois had the most potent ${\beta}-glucuronidase-inhibitory\;activity$. Termaliae Fructus, Amomi Tsa-ko Fructus and Arecae Semen were also potent inhibitors. Among ethyl acetate extract of them, Galla Rhois had the most potent ${\beta}-glucuronidase-inhibitory\;activity$. Nelumbinis Semen. Ephedrae Radix and Termaliae Fructus were also potent inhibitors. The extract of Galla Rhois had potent hepatoprotective effect on $CCl_4-induced$ hepatotoxicity of rats. These results suggest that the ${\beta}-glucuronidase$ seems to be closely related to the liver injury, which could be prevented by the inhibitor of ${\beta}-glucuronidase$.

Depression is associated with a dysfunctional serotonin (5-hydroxytryptamine; 5-HT) system. More recently, several lines of evidence suggest that an important factor in the development of depression may be a deficit in the function and expression of $5-HT_{1A}$ receptors. The present study assessed if Nelumbinis Semen (N. s.) had an anti-depression effect through reversing a decrease in $5-HT_{1A}$receptor binding in rats with depression-like symptoms induced by chronic mild stress. Using a $5-HT_{1A}$ receptor binding assay, with a specific $5-HT_{1A}$receptor agonist, 8- OH-DPAT (8-hydroxy-2-(di-n-propylamino) tetralin), the mechanism of the anti-depression effect of N. s. on rats was investigated, and the effects compared with two well-known antidepressants, Hyperium Perforatum (St. Johns Wort) and fluoxetine (Prozac). Animals were divided into five groups: the normal (N) group without chronic mild stress (CMS), the control (C) group under CMS for 8 weeks, the Nelumbinis Semen (N. s.) treatment group under CMS for 8 weeks, the Hyperium Perforatum (H. p.) treatment group under CMS for 8 weeks and finally, the fluoxetine (F) treatment group under CMS for 8 weeks. Each treatment was administered to rats during the last 4 weeks of the 8-week CMS. A sucrose intake test was performed to test the anti-depression effect of N. s. The N. s. treatment significantly reversed the decreased sucrose intake under CMS (P<0.05 compared to control group under CMS). In the CA2 and CA3 regions of the hippocampus, both N. s. and H. p. reversed the CMS-induced decrease in $5-HT_{1A}$receptor binding. In the I to II regions of the frontal cortex, N. s. and H. p. also reversed the CMS-induced decrease in$5-HT_{1A}$receptor binding, and even showed a significant increase in $5-HT_{1A}$receptor binding compared to the F treatment group (N. s. vs. P, p<0.05, H. p. vs. P, p<0.05). However, in the hypothalamus, all treatments reversed the CMSinduced decrease in $5-HT_{1A}$receptor binding. This reversal effect of N. s. on the decrease in $5-HT_{1A}$receptor binding in the frontal cortex, hippocampus and hypothalamus of rat brains was very similar to that of H. p, but different from that of F. It is concluded that N. s. presents an anti-depression effect through enhancing $5-HT_{1A}$receptor binding.

Objectives: This study aims to review the herbal medicines containing substances banned by World Anti-Doping Agency(WADA), and to consider criteria for the using of herbal medicines. Methods: Using foreign(Pubmed, Cochrane, Embase, Google Scholar, WANFANG, CiNii) and domestic databases (NDSL, OASIS, RISS), we analyzed the content and pharmacokinetics of the prohibited substances in herbal medicines. Results: Herbal medicines containing the prohibited substances proposed in Korea, China, and Japan are Ephedrae Herba, Cannabis Semen, Strychni Semen, Strychni Ignatii Semen, Pinelliae Tuber, Rhizoma Pinelliae, Chelidonii Herba, Papaveris Fructus Deseminatus, Liriopis Tuber, Rehmanniae Radix Recens, Cistanchis Herba, Ponciri Fructus Immaturus, Aurantii Fructus Immaturus, Moschus, Testudinis Plastrum, Otariae Testis et Penis, and Hominis Placenta. Of these, when using Ephedrae Herba, Cannabis Semen, Strychni Semen, Moschus, Strychni Ignatii Semen, and Otariae Testis et Penis, caution is needed in relation to the doping test. Other herbal medicines are considered safe for the doping test. In addition, by analyzing data related to higenamine added to the WADA's prohibited list of doping since 2017, we don't recommend using Nelumbinis Plumula. And in the case of the other herbal medicines containing higenamine, it is considered that care should be taken in doping test depending on the amount of usage. Conclusions: As a result of analyzing the herbal medicines which are in prohibited list about doping, we were able to know the criteria and precautions to use when prescribing the herbal medicines. Further research will be needed about common used herbal medicines and the amount of detection depending on extraction and boiling method.
