PHÂN TÍCH ĐỒNG THỜI CÁC HỢP CHẤT AUXIN VÀ GIBBERELLIN TRONG RAU XANH

Tóm tắt

In this study, auxin and gibberellin compounds in vegetables were simultaneous analyzed using HPLCESI-MS2
. The method shows good linearity for all compounds including IAA, IBA, ICA, IPA, GA3, GA4,
and GA7 with R2 > 0.996. The method detection limit (MDL) and method quantification limit (MQL)
were 2,1-32,6 ng.g-1 and 6,9-108,6 ng.g-1
, respectively. In addition, the matrix effect ranged from 85-
118% whereas the overal recovery was dropped into the range of 90,58-102,56%, and RSD was in
0,44-15,25%. The data indicated that the innovation method was simple, accurate, and efficient for the
analysis of auxin and gibberellin in vegetable tissues. It could be further studied to develop and apply
this method in analyzing plant growth regulators in fruits and agricultural products.
