The physicochemical properties of deodeok (Codonopsis lanceolate) was investigated in relation to the different steaming time and cycles of steaming and drying (S/D). Additionally, the quality characteristics of Makgeolli with different amount (0-0.45%) of steaming and drying deodeok (SD) were measured comparison to non-steaming and drying deodeok (NSD). L⁎ values of deodeok tended to decrease as the number of S/D cycles and steaming times increased, while BI showed the opposite trend for L⁎ values. Reducing sugar increased significantly from 1 to 3 S/D cycles and decreased thereafter (p<0.05). Also, processed with steaming for 4 h and 5 S/D cycles had the highest antioxidant properties. Principal component analysis (PCA) revealed that the S/D process notably influenced the properties of deodeok. Quality characteristics of Makgeolli showed that 0.45% SD resulted in higher antioxidant properties than control or NSD.

To evaluate the mineral value , 27 samples of the wild Codomopsis Lanceolate used for herbs and sidedish were analyzed . All C.Lance-olate, though they inhabit in various zones , contain 21minerals inthe leaf , shoot and root. The richest mineral contained in the C.Lanceolate was noticed to be K. and folLowed by Mg, Ca and p. Thecontent of K.Mg, Ca .p and Fe is higher in the leaf than in theshoot and root. The content of mineral value is quite variousaccording to the geographical difference .

In an attempt to analyse the variation of chromosome numbers in Cododopsis lanceolate, 28 species of Deo-Deong have been examined for determination of chromosomenumbers. Tlle somatic chromosone numbers were counted to be 2n=16 of C. lanceolata.

The effect of ethanol extracts of Gilkyung(Platicodi Radix, Platicodongrandiflorum A, DC), Onji(Polygalae Radix, Polygala tennuifolia Willdenow) and Deoduk(Codonopsis lanceolate Radix, Codonopsis lanceolata) on expectorant activity of rat trachea was investigated. Following treatment of 50% ethanol extract of these medicinal plants (25 mg/rat), the content of neurotransmitters such as acetylcholine and histamine in tissue was significantly increased. The secretions of acid glycoproteins and the artificially injected phenol red were also increased. However, there was no significant difference except Onji From the histological study through periodic acid Schiff and alcian blue stain, the thickness of inner membrane of acinar glands and the stained glycoproteins on surface of epithelium and on the glands were observed in all the rats trachea treated with extract of medicinal plants. In vitro, the viscosity of mucin solution was slightly decreased with an addition of the extracts. Onji showed the most effective expectorant activity among them at the identical conditions. The mechanism of expectorant activity of these medicinal plants seems to be due to stimulation of secretion and changes of rheological properties of mucus.

As the aging population increases and interest in well-being increases, the importance of developing special crops increases. Natural medicine based on the special crops has been mainly used as an adjunct therapy for many diseases and symptoms based on culture, traditional medicine, and experience. In particular, it is attracting attention as a new resource to develop new drugs such as Artemisinin, a treatment for malaria. In order to efficiently use crops, it is essential to establish omics data such as genomes, transcriptomes, and metabolites of special-purpose crops. However, many special-purpose crops have large, heterogeneous and polyploid genomes that require high cost and long time to reference genome sequencing. Therefore, we built an inexpensive, fast, but very usefill reference transcriptome as the first step. We constructed high-quality reference transcriptom sets of Codonopsis lanceolata and Ixeridium dentatum with PacBio data. Our team will continue to construct reference transcriptoms of more special-purpose crops, and the data will be released by the National Agricultural Biotechnology Information Center (NABIC) in order to be widely used in agricultural as well as medical R&D.

The effects of bioactivity, binding polyphenolic contents, DPPH radical scavenging activity, ABTS radical scavenging activity, xanthine oxidase and immune activity on the storage temperature and durations of Codonopsis lanceolata root were evaluated in vitro. The contents of total polyphenol and flavonoid content by storage temperature and storage period was no significant difference according to the storage period, but it was found that the content was higher at lower storage temperature. The DPPH free radical scavenging activity at six different concentrations, 500, 1000, 2500, 5000, 10000 and 20000 mg/L are measured, the scavenging activity according to different storage temperature and storage period showed relatively the higher the activity in the shorter storage period or the lower storage temperature. The ABTS radical scavenging activity did not show a significant difference under various storage temperature and storage period conditions. The xanthine oxidase inhibitory activity of C. lanceolata extract tended to decrease more, depending on the longer storage period or the higher storage temperature. In different storage period and storage temperature conditions, the immune cell growth of C. lanceolata extract promoted a concentration-dependent manner in both human T cell and B cell, and did not show a significant difference. These results of this study suggested that the root of C. lanceolata may assist in the potential biological activities, and can be used as a source of human health products.
