Objectives:The purpose of this paper was to construct a reliable methodology to discriminate the geographical origins of Chuanminshen violaceum Sheh et Shan planted in different regions in Sichuan,China.Materials and methods:fatty acid profiles of roots and leaves of C.violaceum planted in various regions of Sichuan Province in China,namely Guangyuan(GY),Langzhong(LZ),Jintang(JT),Bazhong(BZ),and Shuangling(SL),were determined using GC-MS followed by multivariate statistical analyses,including orthogonal partial least-squares discriminant analysis and hierarchical clustering analysis.Results:Leaves of C.violaceum showed the highest contents of hexadecatrienoic acid(3.21 g/kg),linoleic acid(6.62 g/kg),andα-linolenic acid(7.24 g/kg),which were all higher than those contained in roots.Chuanminshen violaceum samples collected from LZ,JT,and GY could be clearly distinguished based on fatty acid profiles of leaves and those collected from LZ,GY,and BZ could be clearly distinguished based on fatty acid profiles of roots.Conclusions:Chemometric method is used as a potential approach for analyses of fatty acid profiles of roots and leaves to control the quality of C.violaceum and their powered products.

Optimal profile and quantity of fatty acids in rapeseed are very critical for maximizing thevalue of edible oil and biodiesel.Genome-wide association study(GWAS) could efficiently identify the genes and their network underlying complex traits and provide molecular markers to accelerate breeding.In this study,weperformed GWAS todissect the genetic variations of eightseed quality traits in a rapeseed population comprising370 diverse accessions.Seven common SNPs for the contents of seed oiland proteinwere detected on five chromosomes,and five genes orthologous to functionknown Arabidopsis genes were predicted as candidate genes.Genomic region of reduced variation aroundFAE1 loci onA08 and C03 chromosomes controlling the content of erucic acid showed that these two regions were strongly selected during breeding.With the re-sequencing data,we found,except the known haplotypes combination of the variations of BnaA.FAE1 and BnaC.FAE,three accessions contained an additional haplotype combination controlling the moderate content of erucic acid.This study reveals the genetic variations and complex correlations of eight quality traits,which may inform breeding selection strategies for traits in crops.

Developing a method of adulteration detection is critical for protecting customers' rights which is a particular concern in food quality.In this study,fatty acid profiles of castor oils were established by GC and employed to classify 4 types of edible oils and castor oil with multivariate statistical methods.The results indicated that fatty acid profiles of edible oils could be used to classify the 5 kinds of oils.Meanwhile,simulated data test indicated that fatty acid profiles could be used to detect adulterated by 5％.Finally,a RF model was built to detect adulteration of edible oils with castor oils by fatty acid composition.The results from cross validation indicated that the oils adulterated by castor oil at low levels (5％,V/V) could be completely separated from 4 kinds of edible oils.Therefore this model could be used to detect adulteration of 4 kinds of edible oil with castor oils.
