Abstract

<abstract abstract-type="main" id="ijfs12814-abs-0001"> <title>Summary</title> <p>High‐performance liquid chromatography (HPLC) with evaporative light scattering detector (ELSD) and quadrupole time‐of‐flight mass spectrometry (Q‐TOF‐MS) were used for qualitative and quantitative analysis of wild <italic>Panax</italic> species, especially wild <italic>P. vietnamensis, </italic> which is an important medicinal plant. We determined the types and concentrations of ginsenosides in radix and rhizome of wild <italic>P. vietnamensis</italic>. Identification of ginsenosides was achieved using Q‐TOF‐MS; concentrations were determined by ELSD. The most abundant ginsenosides in wild Vietnamese ginseng were of the ocotillol type, accounting for more than 50% of the total. Compared to the rhizome, the radix had 31% higher ginsenoside content due to variation in protopanaxatriol‐type ginsenoside contents. We also found an unusual difference in the chromatograms of the two parts of wild <italic>P. vietnamensis</italic>. This difference did not appear in other wild species such as <italic>P. ginseng</italic> and <italic>P. quinquefolius</italic>. Our study provides an opportunity for further in‐depth study of the distinctive characteristics of <italic>P. vietnamensis</italic>.</p> </abstract>
