ABSTRACT

OBJECTIVE To study the quality difference of different specifications of Citri Grandis Exocarpium from different origins,and to provide reference for the orderly development of Citri Grandis Exocarpium industry. METHODS Different specifications [ Citrus grandis ‘Tomentos’young fruit ,Citrus grandis (L.)Osbeck young fruits ,exocarp] of 93 batches of Citri Grandis Exocarpium medicinal materials (decoction pieces )from different origins [ Citrus grandis ‘Tomentosa’or Citrus grandis (L.)Osbeck] were taken as samples. The contents of naringin and rhoifolin in samples were determined by HPLC. Through pheatmap parameters of R language ,heatmap was drawn for the contents of naringin and rhoifolin according to origins and specifications (young fruit and exocarp ). RESULTS Of 93 batches of samples ,the contents of naringin and rhoifolin were 16.52-214.64 and 1.03-10.96 mg/g,respectively. Among different specifications ,the contents of naringin and rhoifolin in the young fruit were the highest (their average contents were 108.96 and 6.30 mg/g respectively ). Heatmap analysis of R language content showed that the contents of naringin and rhoifolin in Citri Grandis Exocarpium from origin of C. grandis ‘Tomentosa’were generally higher than those from origin of C. grandis (L.)Osbeck. Of different specifications of Citri Grandis Exocarpium from origins,the contents of naringin and rhoifolin were higher in KTP young fruit relatively. CONCLUSIONS The quality of Citri Grandis Exocarpium from origin of C. grandis ‘Tomentosa’with the young fruit as specification is the best.
