Analysis of geniposide and crocin contents in fruits of different leaf-fruit types of gardenia
In order to provide some references for evaluation of gardenia germplasm resources as well as development and exploitation of their active ingredients,using 6 kinds leaf-fruit types of gardenia trees (60 in number) as materials,morphological parameters of leaves and fiuits,and contents of geniposide and crocin in fruits were observed and analyzed.The results showed that contents of geniposide and crocin in fruits had significant differences between gardenia plants from a cultivation population,which respectively ranged from 1.75％ to 5.60％ and from 0.33％ to 4.05％,and geniposide contents in fruits had significant differences between big-fruit gardenia and middle-and small-fruit gardenia.The results of correlation analysis showed that geniposide content had significant positive correlation (r =0.280) with fruit vertical diameter,and extremely significant positive conrelation (r =0.482) with crocin content,while other morphological parameters had no significant correlation with contents of geniposide and crocin.The results of the stability test showed that contents of geniposide and crocin in most plant samples were stable within two years,but the two indexes in few ones had an abrupt increase.The plants from a cultivation population had rich genetic diversity,and contents of geniposide and crocin in their fruit were obviously influenced by hereditary polarization.
