This paper aimed to analyze the marker compounds from the roots of T. kirilowii and evaluate a validation method for cucurbitacins B and D using high-performance liquid chromatography-photodiode array detector (HPLC-PDA). Two marker compounds were identified as cucurbitacin B (1) and cucurbitacin D (2) from the roots of T. kirilowii by spectroscopic analyses. Cucurbitacins B and D peaks were well separated and were detected at 15.4？min and 12.4？min, respectively, by a UV detector at 230？nm with the linearity (R2？>？0.999) range between 5 and 250？μg/mL, limit of detections (LODs) were 1.87？μg/mL and 1.30？μg/mL, respectively, while limit of quantifications (LOQs) were 5.66？μg/mL and 3.93？μg/mL, respectively. The established method offered good precision with overall intra- and inter-day variations of 0.34？1.26 and 0.26？1.35%, respectively, for % relative standard deviation (RSD, acceptance limit %RSD <3%). The cucurbitacins B and D recoveries ranged from 99.2 to 101.7% and 98.6 to 102.0%, respectively. These results suggest that cucurbitacins B and D could be a valuable candidate for marker compounds of the extract from T. kirilowii, and the proposed method was shown applicability for quality control of SH003.
