To evaluate the functional germplasm resources of Cymbopogon citratus, the differences in betaine, alkaloid and flavone contents were analyzed. 45 C. citratus from Hainan, Fujian, Guizhou and Yunnan were evaluated by analyzing the content of betaine, alkaloids and flavonoids. The water extract of C. citratus mainly contained flavonoids (24.30%), alkaloids (13.53%) and betaine monomers (10.52%). The betaine content of HK-2 was the highest, reaching 5.65 mg/g. The alkaloid content of HK-1-1 was the highest, reaching 8.66 mg/g. The flavonoid content of YX-1 was the highest, reaching 43.15 mg/g. There were significant differences in the content of betaine, alkaloid and flavonoid in different storage locations, regions and altitudes of the resources. The mouse model of constipation induced by loperamide demonstrated that betaine had the effect of moistening the intestines and promoting bowel movements. Finally, based on the established functional resource evaluation method for C. citratus, first-class C. citratus resources YX-1, WN-2, GM-1, ZZ-1, RL-1 and YJ-4 were selected. The results of this study are helpful for the screening, evaluation and breeding utilization of functional resources of C. citratus, and could also provide scientific basis for the study of functional mechanisms and the development and utilization of functional products.
