자음강화탕(Jaeumgangwha-tang, JGT)은 전통적인 한방처방으로, 만성 기관지염과 염증 질환 등을 치료하는데 사용된다. 자음강화탕을 10종의 균주로 발효한 후, HPLC-DAD를 이용하여 발효 전, 후의 자음강화탕에서 생물활성을 가지는 5-hydroxymethylfurfural(5-HMF), paeoniflorin, nodakenin, hesperidin, nodakenetin, palmatine, berberine, glycyrrhizin을 지표성분으로 설정하고 변화를 관찰하였다. 8종의 지표성분에 대하여 정성, 정량적인 동시분석을 수행하였고 머무름 시간($t_R$)과 UV 최대 흡수파장을 비교하였다. 이 결과 paeoniflorin이 6.95 mg/g으로 자음강화탕의 주성분으로 확인되었다. Lactobacillus fermentum KFRI 145으로 발효된 자음강화탕에서 nodakenetin의 함량이 $0.47{\pm}0.01mg/g$으로 관측되어 nodakenetin이 발효 후의 자음강화탕에서 발효 전보다 2,250% 증가한 것을 확인하였다. 또한 Lactobacillus acidophilus KFRI 162으로 발효된 자음강화탕에서 paeoniflorin과 hesperidin을 제외한 가장 많은 화합물들이 증가하는 것을 확인하였다.

Gumiganghwal-tang (GMT) is a traditional herbal prescription used for treatment of the common cold, pain, and inflammatory diseases. Variations in the amounts of bioactive components of GMT and GMT fermented with 10 Lactobacillus strains were investigated by high-performance liquid chromatography coupled with diode array detection (HPLC-DAD). Simultaneous qualitative and quantitative analyses of eleven bioactive compounds (prim-O-glucosylcimifugin, liquiritin, cimifugin, baicalin, liquiritigenin, wogonoside, baicalein, wogonin, butylphthalide, imperatorin, and isoimperatorin) were performed, with comparison of their retention times (tR) and UV spectra with those of standard compounds. The amounts of baicalin (8.71 mg/g), liquiritigenin (5.28 mg/g) and butylphthalide (5.10 mg/g) were the major compounds in GMT. We found that L. fermentum KFRI 145 fermented wogonoside and baicalin to their aglycones, wogonin and baicalein, respectively. These results indicated that L. fermentum KFRI 145 has potential as a functional starter culture for manufacturing fermented GMT.

We developed a method to identify and quantify 6-hydroxyluteolin 7-O-glucoside in the powder of Salvia plebeia (PS) using high-performance liquid chromatography coupled with diode array detector (HPLC/DAD) and equipped with reverse-phase INNO C18 column. The analytical method was optimized and validated using novel parameters. The obtained values for the limits of detection and quantification were 3.60 and 10.90 ㎍/mL, respectively. Calibration curve showed good linearity in the concentration range tested (0.00625-0.1 mg/mL, r² = 1.0000), high accuracy (96.2-101.4%), and precision values (RSD ≤ 0.27%). Our analysis support the use of our method for accurately identifying and quantifying 6-hydroxyluteolin 7-O-glucoside from PS in routine analyses and large-scale extraction processes for content determination.

Samchulgeonbi-tang (SC) is well-known traditional herbal medicine which is composed of fourteen medicine herbs. SC has been used for the treatment of the chronic gastritis, indigestion, gastric ulcers, gastroptosis and diarrhea disease. The variation in the amount of bioactive components of SC and its fermentation SC with ten Lactobacillus strains were investigated via high-performance liquid chromatography coupled with diode array detection (HPLC-DAD). Simultaneous qualitative and quantitative analysis of seven bioactive compounds; paeoniflorin, liquiritin, hesperidin, liquiritigenin, kaempferol, atractylenolide III, magnolol were achieved by comparing their retention times ($t_R$) and UV spectra with those of the standard compounds. In the results, the amount of paeoniflorin and hesperidin were 7.967 mg/g, 7.251 mg/g that were the main compounds in SC. The amounts of liquiritigenin was increased by all ten Lactobacillus strains, except strain 128. Especially, the liquiritigenin amount was highest in SC fermented with strain 145 (0.201 mg/g), which was increased by 158.39% compared to SC (0.081 mg/g). In the fermented SC using strains 344, almost components were increased than non-fermented SC, except paeoniflorin and kaempferol. Thus, these results considered that the strains 145 and 344 are most excellent fermentation strains among the 10 species of fermentation strains.

Background: Ginsenosides are the characteristic and principal components which manifest a variety of the biological and pharmacological activities of the roots and rhizomes of Panax ginseng (GRR). This study was carried out to qualitatively and quantitatively determine the ginsenosides in the cultivated and forest GRR. Methods: A rapid and sensitive ultra-high-performance liquid chromatography coupled with diode-array detector and quadrupole/time of flight tandem mass spectrometry (UPLC-DAD-QTOF-MS/MS) was applied to the qualitative analysis of ginsenosides and a 4000 QTRAP triple quadrupole tandem mass spectrometer (HPLC-ESI-MS) was applied to quantitative analysis of 19 ginsenosides. Results: In the qualitative analysis, all ingredients were separated in 10 min. A total of 131 ginsenosides were detected in cultivated and forest GRR. The method for the quantitative determination was validated for linearity, precision, and limits of detection and quantification. 19 representative ginsenosides were quantitated. The total content of all 19 ginsenosides in the forest GRR were much higher than those in the cultivated GRR, and were increased with the growing ages. Conclusion: This newly developed analysis method could be applied to the quality assessment of GRR as well as the distinction between cultivated and forest GRR.

Hwangryunhaedok-tang (HRT) is a traditional herbal medicine, which has been known as a useful prescription for anti-biotic, anti-inflammatory, anti-oxidative and immunosuppressive activity. In this study, the variation in the amount of eight bioactive components of Hwangryunhaedok-tang (HRT) and its fermentation HRT with Lactobacillus casei KFRI 127, Lactobacillus curvatus KFRI 166 and Lactobacillus confuses KFRI 227 was investigated via high-performance liquid chromatography coupled with diode array detection (HPLC-DAD). Simultaneous qualitative and quantitative analysis of eight bioactive components; geniposide, genipin, baicalin, wogonoside, palmatine, berberine, baicalein and wogonin was achieved by comparing their retention times ($t_R$) and UV spectra with those of the standard components. All calibration curve of standard components showed good linearity ($r^2$ >0.979). As a result, the geniposide amount was $15.52{\pm}0.19{\mu}/mg$ that as a main components in HRT. The wogonoside was decreased by 29.28~58.35% with Lactobacillus casei KFRI 127 and L. confuses KFRI 227 ($3.17{\pm}0.31{\mu}g/mg$ and $3.55{\pm}0.13{\mu}g/mg$) compared with the original HRT ($5.02{\pm}0.14{\mu}g/mg$). Otherwise wogonin was increased by 16.28~41.86% with Lactobacillus casei KFRI 127 and L. confuses KFRI 227 ($0.61{\pm}0.01{\mu}g/mg$ and $0.50{\pm}0.02{\mu}g/mg$) compared with the original HRT($0.43{\pm}0.00{\mu}g/mg$). HRT fermented with L. casei KFRI 127 and L. confuses KFRI 227 were evaluated as creating the changes in wogonoside to that aglycon wogonine. In the fermented HRT using Lactobacillus acidophilus KFRI 166, the genipin was only detected, among 3 species of fermentation strains. Thus, these results considered that the strains 166 were exhibited the remarkable changes in genipin.
