To better understand the role of the dynamics of B vitamins in different tissues in Areca triandra,this study determined and analysed the content of B vitamins in the four development stages of endosperm and peri-carp,leaf tissue at different stages of maturity,male and female flowers and inflorescences of the A.triandra by ultra-high liquid chromatography-triple quadrupole tandem mass spectrometry(UPLC-MS/MS).The results showed that nine water-soluble B vitamins(including thiamin,riboflavin,niacin,nicotinamide,pantothenic acid,pyridox-ine,biotin,folic acid and cyanocobalamin)were detected in the A.triandra.The amount of the same vitamin varies considerably in different tissues.The most abundant B vitamins in the tissues of the A.triandra are thiamine and pantothenic acid.The content of B vitamins showed different dynamics in different tissues and developmental stages.The distribution of B vitamins in A.triandra has the characteristics of tissue specificity and maturity depen-dence.Different B vitamins showed different accumulation patterns during the development of the pericarp and en-dosperm of A.triandra.In addition,correlation analysis found that thiamine was significantly positively correlated with niacin,pyridoxine was significantly positively correlated with cyanocobalanim,and riboflavin was significantly positively correlated with biotin.This study provides a reference for exploring the contents of B vitamins in differ-ent tissues of the A.triandra and the dynamic accumulation patterns of B vitamins content in fruits and leaves at different developmental stages.
