Rumex crispus (RC) or Cordyceps militaris (CM) has been used traditionally to treat various diseases and has been also consumed as a functional food made by humanitas medicine concept. We prepared a new herbal mixture, AST2017-01 which is mainly composed of processed (Beopje)-RC (P-RC) and -CM (P-CM). This study aims to validate marker compounds (chrysophanol and cordycepin) in P-RC and P-CM and water extracted-RC and -CM using liquid chromatography-tandem mass spectrometry. In addition, we analyzed contents of chrysophanol and cordycepin in AST2017-01. The linarites of chrysophanol and cordycepin were obtained in calibration curve with a coefficient of correlation of 0.999. The results showed that the concentrations of chrysophanol and cordycepin in P-RC and P-CM were almost 1.70 and 1.23 fold higher than that in RC and CM, respectively. Furthermore, contents of chrysophanol and cordycepin in the AST2017-01 are approximately 0.13% and 0.028%, respectively. In conclusion, these results indicate that chrysophanol and cordycepin were validated as marker compounds in the AST2017-01.

Rumex species (Polygonaceae) is widely distributed in Korea and its little sprout has been used as wild greens. The roots of Rumex sp. are used as a substitute for Rhei Rhizoma in Korea for its antipyretic and laxative properties. For the purpose of researching the value of Rumex sp. plants as natural resources, pattern recognition for the analysis of those plants was conducted using HPLC method. Two anthraquinone compounds, chrysophanol and emodin, were isolated from Rumex crispus to use standards. Chrysophanol and emodin from R. crispus were detected at retention time of 14.96 and 12.21 min, respectively. These compounds were detected from Rhei Rhizoma and all Rumex sp. plants. The content of chrysophanol of R. conglomeratus was higher than any other Rumex sp. plants. The amount of emodin was much higher from R. crispus than any other Rumex sp. The HPLC patterns of Rumex sp. are similar to that of Rhei Rhizoma, so they have something valuable as natural resources.

천연물을 기반으로 한 신약 개발은 일반적으로 오랜 기간 동안의 원료 약물로써 사용해 온 경험에 의한 다양한 임상적 결과의 축적과 이로 인한 안정성(stability)과 안전성(safety)의 확보 및 신약 개발 시간의 단축과 같은 이점을 가지고 있어, 천연물 유래 약물 연구는 꼭 필요한 실정이다. 다양한 신경질환에서 신경세포의 사멸과 미세아교세포의 과도한 활성화 즉 뇌염증이 관찰되며 이를 억제할 수 있는 물질에 대한 연구는 활발히 진행 중이지만, 현재까지 신경세포 사멸과 뇌염증을 동시에 억제하는 물질 개발 시도는 거의 없었다. 따라서, 본 연구에서는 천연물에서 추출한 물질로 총 240개로 구성된 라이브러리로부터 신경전달물질 중의 하나인 glutamate 과잉처리에 의한 산화적 스트레스 유도 신경세포(HT22) 사멸과 LPS에 의한 미세아교세포(BV2)의 과도한 활성화 즉 뇌염증의 표지 인자 중 하나인 NO의 생산량의 감소 효과가 동시에 나타나는 물질을 검출한 결과, 대황에서 추출한 Chrysophanol이 검출되었으며 더욱이 Chrysophanol이 신경세포와 미세아교세포 모두에서 glutamate와 LPS에 의해 각각 유도된 세포내 활성산소(ROS) 발생을 억제하는 것을 확인하였다. 앞으로 Chrysophanol에 대한 보다 깊은 연구를 통하여 산화적 스트레스에 의한 신경세포 사멸과 미세아교세포의 과잉 활성화에 따른 뇌염증의 발생을 동시에 억제하는 신경질환의 치료 및 예방 신약개발 후보 물질 가능성을 제시 하고자 한다.

In this study, we performed quantification determination of four major components including aurantio-obtusin, emodin, chrysophanol, and physcion in the 70% ethanol extracts of non-processed Cassiae Semen and processed Cassiae Semen using a high-performance liquid chromatography coupled with photodiode array detector. The analytical column for separation of the 4 constituents used a Gemini $C_{18}$ column kept at $40^{\circ}C$ by the gradient elution with 1.0% (v/v) acetic acid in water and 1.0% (v/v) acetic acid in acetonitrile as mobile phase. The flow rate was 1.0 mL/min and the injection volume was $10{\mu}L$. The amount of aurantio-obtusin, emodin, chrysophanol, and physcion in non-processed Cassiae Semen were 0.07%, 0.02%, 0.25%, and 0.10%, respectively. The amount of aurantio-obtusin, emodin, chrysophanol, and physcion in processed Cassiae Semen were 0.04-0.14%, 0.01-0.03%, 0.02-0.42%, and 0.01-0.24%, respectively. Consequently, the optimal processing condition of Cassiae Semen for the improvements of amounts of four anthraquinone compounds was obtained by roasting at $240^{\circ}C$ for 15 min.

Background: In the present study, we identified two cytotoxic compounds from the root of Rumex crispus L. using a bioassay-based method. Methods and Results: Compared with the other fractions, the diethyl ether ($Et_2O$) fraction of R. crispus root extract exhibited the strongest of 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical-scavenging effect [scavenging concentration 50% $(SC_{50})=63.8{\pm}1.47{\mu}g/m{\ell}$], nitric oxide (NO) production inhibitory effect on the mouse macrophage cell line RAW264.7 [inhibitory concentration 50% $(IC_{50})=60.9{\pm}7.52{\mu}g/m{\ell}$] and cytotoxicity effect on the human hepatoma cell line, HepG2 [lethal concentration 50% $(LC_{50})=115.4{\pm}1.86{\mu}g/m{\ell}$]. According to the bioassay-based method, two cytotoxic compounds were purified from the $Et_2O$ fraction by using column chromatography and preparative high performance liquid chromatography (prep-HPLC). These two compounds were identified as parietin and chrysophanol by using nuclear magnetic resonance (NMR) and liquid chromatography quadruple time of flight mass spectrometry (LC-QTOF-MS). In addition, both parietin and chrysophanol exhibited a cytotoxicity effect on HepG2 cells, their $LC_{50}$ values were $169.1{\pm}17.67{\mu}M$ and $111.5{\pm}6.62{\mu}M$, respectively. Conclusions: Parietin and chrysophanol isolated from the $Et_2O$ fraction of the R. crispus root extract showed cytotoxicity in HepG2 cell.

Objective: Polygonum multiflorum Thunberg (Polygonaceae) has been traditionally used as a tonic and the purgative in China and Korea. The genus Polygonum is a source of a wide range of phenolic compound, flavanoids, anthraquinones, stilbenes and tannins. In this study, three anthraquinones were isolated and quantitative determination of anthraquinones from P multiflorum has been developed for quality standardization. Methods : Three anthraquinone derivatives were isolated from a methanol extract of the radix of P. multiflorum by the chromatographic separation. Their structures were identified as emodin, physcion and ${\omega}$-hydroxyemodin on the basis of spectral data (MS, lH-NMR, 13C-NMR) and chemical analysis. HPLC analysis was performed to determine the contents of emodin, physcion, chrysophanol, rhein and ${\omega}$-hydroxyemodin in P. multiflorum from different specimens were collected from twenty Korean markets. Results: According to the results, the contents of emodin, physcion, chrysophanol, rhein and ${\omega}$-hydroxyemodin were 0.145%, 0.434%, 0.016%, 0.026%, 0.030% by HPLC, respectively. Conclusions : In these results, we have determined the contents of emodin, physcion, chrysophanol, rhein and ${\omega}$-hydroxyemodin in P. multiflorum, respectively. We hope that this study will contribute to the standardization and quality control of herbal medicine.

Recently, consume for functional cosmetics containing natural products has been greatly increased. In order to develop it as a natural cosmetic material, we selected Ixeridium dentatum (Thunb.) Tzvelev, Plantago asiatica L. and Rumex crispus L. that have antioxidant and anti-inflammatory effects. In this study, simultaneous quantitative analysis of the isolated compounds and natural product complexes (Mix.) were validated using high performance liquid chromatography (HPLC). The isolated six compounds were shown in a large linearity with a correlation coefficient (R²) of 0.99. The limit of detection (LOD) of chlorogenic acid, plantamajoside, acteoside, emodin chrysophanol and physcion were 0.36 ㎍/mL, 0.36 ㎍/mL, 0.37 ㎍/mL, 0.30 ㎍/mL, 0.22 ㎍/mL and 0.12 ㎍/mL, respectively. The limit of quantification (LOQ) of chlorogenic acid, plantamajoside, acteoside, emodin chrysophanol and physcion were 1.10 ㎍/mL, 1.08 ㎍/mL, 1.12 ㎍/mL, 0.99 ㎍/mL, 0.66 ㎍/mL and 0.35 ㎍/mL, respectively. Content analysis showed chlorogenic acid (0.19 ± 0.02%), plantamajoside (0.48 ± 0.01%), acteoside (0.65 ± 0.01%), emodin (1.15 ± 0.11%), chrysophanol (0.73 ± 0.01%) and physcion (0.69 ± 0.09%). Therefore, the results of this study may provide for basic data of standardization research natural cosmetic material development on the I. dentatum, P. asiatica and R. cripus.
