In this study, Jeolpyon(imprinted with flow patterns) was prepared with different amount of added Astragalus membranaceu extracts(0%, 3%, 6%, 9% and l2%)and then the quality and sensory characteristic effects were examined. All togather the chemical composition of the samples was as follows: $53.l2{\pm}0.04%$ of moisture, $l4.43{\pm}0.05$ crude protein, $7.6l{\pm}0.11%$ crude fat, and $21.35{\pm}0.09%$ crude ash. Hardness and cohesiveness significantly increased(p <0.001), and springiness, chewiness and adhesiveness decreased, with increasing amounts of Astragalus membranaceus extract. In the chromaticity analysis, the L-value(brightness)significantly decreased with increasing Astragalus membranaceus extract content, and the b-value(yellowness) increased in direct proportion to the extract content. Finally, in the sensory evaluation, the Jeolpyon containing 9.0% extract received the highest overall preference scores.

Astragalus membranaceus (A. membranaceus) has traditionally been used as a medicinal plant in East Asia for the treatment ofvarious diseases. A. membranaceus belongs to the legume family and is known to be rich in substances such as flavonoids and saponins. Recent pharmacological studies of A. membranaceus have shown that the plant has immunomodulatory, anti-oxidant, anti-cancer, and anti-inflammatory effects. However, knowledge of major biosynthetic pathways in A. membranaceu is still lacking. Recently developed sequencing techniques enable high-quality transcriptome analysis in plants, which is recognized as an important part in elucidating the regulatory mechanisms of many plant secondary metabolic pathways. However, it is difficult to predict the number of transcripts because plant transcripts contain a large number of isoforms due to alternative splicing events, which can vary depending on the assembly platform used. In this study, we constructed three unigene sets using Pac-Bio isoform sequencing, Trinity and rnaSPAdes assembly for detailed transcriptome analysis mA. membranaceus. Furthermore, all genes involved in the flavonoid biosynthetic pathway were searched from three unigene sets, and structural comparisons and expression profiles between these genes were analyzed. The isoflavone synthesis was active in most tissues. Flavonol synthesis was mainly active in leaves and flowers, and anthocyanin synthesis was specific in flowers. Gene structural analysis revealed structural differences in the flavonoid-related genes derived from the three unigene sets. This study suggests the need for the application of multiple unigene sets for the analysis of key biosynthetic pathways in plants.

Objectives: The purpose of this study was to investigate the antineoplastic effect of several herbal medicine mixtures (compositions of Astragalus membranaceu, Angelica gigas, Trichosanthes kirilowii, Panax ginseng, Rhus verniciflua Stokes) on the SNU-80 anaplastic thyroid carcinoma cell line. Methods: MTT assay was used to examine whether our herbal medicine mixtures decreased cell growth rate of SNU-80. Wound healing assay and Transwell invasion assay was performed to investigate whether our herbal medicine mixtures affect the migration and invasion of anaplastic cancer cells, SNU-80. ELISA assay was performed to know if our herbal medicine mixtures suppressed the expression of pro-invasive molecules, such as vascular endothelial growth factor (VEGF) and matrix metalloproteinase-2 (MMP-2) secreted from SNU-80. Results: MTT assay demonstrated that A. membranaceus:A. gigas:T. kirilowii=1:1:1 or 3:1:1, A. membranaceus:A. gigas :T. kirilowii:P. ginseng=1:1:1:1 or 3:1:1:1, A. membranaceus:A. gigas:T. kirilowii:P. ginseng:R. verniciflua Stokes=1:1:1:1:1 or 3:1:1:1:1 strongly suppressed the growth of SNU-80. Wound healing assay demonstrated that A. membranaceus:A. gigas=3:1, A. membranaceus:A. gigas:T. kirilowii=1:1:1 or 3:1:1, A. membranaceus:A. gigas:T. kirilowii:P. ginseng=1:1:1:1 or 3:1:1:1, A. membranaceus:A. gigas:T. kirilowii:P. ginseng:R. verniciflua Stokes=1:1:1:1:1 or 3:1:1:1:1 inhibited the migration of SNU-80. Transwell invasion assay demonstrated that A. membranaceus:A. gigas=1:1, A. membranaceus:A. gigas:T. kirilowii =1:1:1 or 3:1:1, A. membranaceus:A. gigas:T. kirilowii:P. ginseng=1:1:1:1, A. membranaceus:A. gigas:T. kirilowii:P. ginseng :R. verniciflua Stokes=1:1:1:1:1 or 3:1:1:1:1 inhibited the invasion of SNU-80. ELISA assay demonstrated that A. membranaceus :A. gigas:T. kirilowii=1:1:1 or 3:1:1, A. membranaceus:A. gigas:T. kirilowii:P. ginseng:R. verniciflua Stokes=1:1:1:1:1 suppressed the expression of VEGF. Also, A. membranaceus:A. gigas=1:1, A. membranaceus:A. gigas:T. kirilowii=1:1:1 or 3:1:1, A. membranaceus :A. gigas:T. kirilowii:P. ginseng=1:1:1:1 or 3:1:1:1, A. membranaceus:A. gigas:T. kirilowii:P. ginseng:R. verniciflua Stokes =1:1:1:1:1 or 3:1:1:1:1 suppressed the expression of MMP-2. Conclusions: The results obtained in this study suggest that several herbal medicine mixtures suppresse the growth and inhibit the migration and invasion of SNU-80, which is anaplastic thyroid cancer cells. Especially, A. membranaceus:A. gigas: T. kirilowii=1:1:1 mixture had a stronger anti-cancer effect.
