A rapid, accurate and precise method for the determination of 22 amino acids in Isatidis Radix by Hydrophilic Interaction Ultra-High-Performance Liquid Chromatography Coupled with Triple-Quadrupole Mass Spectrometry (HILIC-UPLC-MS/MS) was established. Chromatographic separation was carried out on a Acquity UPLC BEH Amide column ($2.1mm{\times}100mm$, $1.7{\mu}m$) with gradient elution of acetonitrile (containing 0.05% formic acid and 2 mM ammonium formate) and water (containing 0.15% formic acid and 10 mM ammonium formate) at a flow rate of 0.4 mL/min; Waters Xevo$^{TM}$ TQ worked in multiple reaction monitoring mode. All components were separated in 17 min. All calibration curves were linear ($R^2$ > 0.991) over the tested ranges. The limits of detection (LOD) and limits of quantitation (LOQ) for these compounds were 0.21-79.55 and 0.72-294.23 ng/mL, respectively. The average recoveries were in the range of 93.75-104.16% with RSD value less than 6.56%. Therefore, this method could be an alternative assay for the determination of 22 amino acids in Isatidis Radix due to its rapidness, sensitivity, less sample and solvent consumption.

Objectives : 판람근(板藍根)은 십자화과에 속하는 대청(大靑) 또는 숭남의 근(根)을 건조한 것이다. 본 연구는 판람근(板藍根)이 청열해독(淸熱解毒)함에 근거하여, LPS로 활성화된 Raw264.7 cell에서 판람근(板藍根)과 그 성분중의 하나인 tryptanthrin이 염증매개물질에 미치는 효과를 살펴보고자 하였다. Methods : 세포생존율은 MTT, nitric oxide (NO)는 Griess reagent를 사용하여 측정하였으며, 각 단백질의 발현량은 Western blot 방법을 사용하였으며, cytokine 및 cyclooxygenase-2 (COX-2)는 ELISA방법을 사용하여 측정하였다. Results : LPS는 NO 및 prostaglandin E2 (PGE2)를 유의하게 상승시켰으며, 판람근(板藍根)추출물 (IRE) 및 tryptanthrin 은 이들을 유의하게 억제하였다. 그러나 판람근(板藍根)의 또 다른 성분인 indigo는 유의한 결과를 나타내지 못하였다. IRE와 tryptanthrin은 inhibitory kappa B alpha의 인산화를 억제하여, nuclear factor-${\kappa}$B (NF-${\kappa}$B)의 핵으로의 전위(轉位)를 억제하여, iNOS 및 cytokine을 억제하였다. IRE와 tryptanthrin의 PGE2 억제는, COX-2의 발현억제에서가 아니라, COX-2의 활성을 억제함에서 기인하였다. Conclusion : 이러한 결과는 판람근(板藍根)이 NF-${\kappa}$B pathway를 경유하여 iNOS의 발현 및 COX-2의 활성을 억제함을 나타내며, 이러한 판람근(板藍根)의 항염증효능은 일부 tryptanthrin의 작용에서 기인함을 시사한다.

The objective of this study was to evaluate effects of a combined use of extracts of medicinal herbs Taraxaumi mongolicum, Viola yedoensis Makino, Rhizoma coptidis, and Radix isatidis (MYCI) on porcine epidemic diarrhea (PED). Twenty-two 3-day-old piglets received an oral challenge with $3{\times}10^{3.5}$ $TCID_{50}$ of the virulent PED virus (PEDV) in PBS or PBS only and daily oral administration of 60 mg of the MYCI mixture suspended in milk replacer or the vehicle for 7 days in a $2{\times}2$ factorial arrangement of treatments. Average daily gain (ADG) increased (p < 0.05) in response to the MYCI treatment in the PEDV-challenged piglets (-18 vs. 7 g for the vehicle- vs. MYCI-administered group), but not in unchallenged animals (27 vs. 28 g). Diarrhea score and fecal PEDV shedding, however, were not influenced by the MYCI treatment. The PEDV challenge caused severe intestinal villus atrophy and crypt hyperplasia, both of which were alleviated by administration of the MYCI mixture as indicated by an increase in the villus height and a decrease in the crypt depth due to the treatment. Overall, medicinal herb extracts used in this study ameliorated impaired growth performance and intestinal lesion of newborn piglets challenged with the virulent PEDV. Therefore, our results suggest that the MYCI mixture could be used as a prophylactic or therapeutic agent against PED.
