dc.description.alternativeAbstractPlant are exposed to various abiotic and biotic stress factors. They produce diverse metabolic substances. To elucidate the change of metabolic profiles by layers, ages, seasons and habitats, Platocodon. grandiflorum sample were collected from November 2013 to September 2014 at five sites : Site 1, 2 and 3 were Balloon flower cultivation fields located in Hongcheon-gun, Kangwon-do. Site 4 is wild P. grandiflorum habitats located in Gangneung-si, Kangwon-do and site 5 is another wild P. grandiflorum habitat in Mt. Daebong. Humidity, electric conductivity, temperature and acidity were measured for soil environmental factors. For gas chromatography mass spectrometry (GC-MS) analysis, MeOH extraction was proceeded by using internal standards (13C-ribitol and 13C-sorbitol). For GC-MS analysis, the extracted samples were derivatizated using methoxiamination and MSTFA (N-Methyl-N-(trimethylsilyl) trifluoroacetamide). Data from GC-MS was analyzed by Automated Mass-Spectral Deconvolution and Identification System (AMDIS), National Institute of Standards and Technology (NIST) library, OpenChrom, MetAlign, MSClust and R program. There were significantly differences in GC-MS profiles of P. grandiflorum between above-ground, such as leaves and below-ground parts. Cortex and epidermis showed slightly different metabolic profiles. Such as epidermis, cortex and pith exhibited distinctive profile patterns by seasons. Between before and after, November 2013 and March 2014, epidermis samples showed very clear differences in profile. After winter, P. grandiflorum had higher sucrose concentration than in November. In the comparison among habitats, epidermis samples showed quiet different profiles from cultivation samples. However there is not clear patterns by ages because of habitat heterogeneity and genetic diversity. To study the effect of microbial communities or metabolic profiles, a growth experiment with different soils was conducted by using plants induced from same callus and stem. I made four type soil : soil of P. grandiflorum cultivation field (CS), autoclaved soil of P. grandiflorum cultivation field (ACS), soil of P. grandiflorum wild habitat (WS) and autoclaved soil of P. grandiflorum wild habitat (AWS). Metabolic profiles of P. grandiflorum were changed by soil condition. Also P. grandiflorum grown from different habitats have similar metabolic profiles after soil autoclaved indicating soil microbial communities may change metabolic profiles of plant below-ground as well as plant above-ground.-
