ZHOU Guo-hong, XU Meng-ying, ZHANG Xiao, et al. Correction of Chemical Structure of Vaccarin According to 2015 Edition of [J]. Chinese journal of experimental traditional medical formulae, 2018, 24(7): 51-55. DOI: 10.13422/j.cnki.syfjx.20180712.
Objective: Correct the chemical structure of vaccarin
which has content limit in Vaccaria segetalis according to the 2015 edition of Chinese Pharmacopoeia. Method: A serial of methods was utilized
such as chemical methods
high performance liquid chromatography (HPLC)
UV Radiation
Infrared Radiation (IR)
nuclear magnetic resonance (NMR) and mass spectra (MS). Result: The glc linked to position 4' of apigenin originally should be linked to position 7
suggesting that the chemical of vaccarin should be apigenin 6-C-[α-L-arabinopyranosyl-(1'"→2″)-β-D-glucopyranosyl]-7-O-β-D-glucopyranoside. Conclusion: The chemical structure of vaccarin should be revised as apigenin 6-C-[α-L-arabinopyranosyl-(1'"→2″)-β-D-glucopyranosyl]-7-O-β-D-glucopyranoside. Vaccarin is the quantitative composition of Vaccariae Semen in the 2015 edition Chinese Pharmacopoeia
which highlights the great significance of the accuracy of its chemical structure.
