Objective AIM To establish the method for Simultaneous determination of Gypenoside A, Ginsenoside Rb1, Gypenoside XLIX,Gypenoside XVII in Gynostemma pentaphyllum by RP-HPLC- ELSD. Methods An Phenomenex C18 column (4.6 mmí250 mm, 5μm) was used with the mixture of acetonitrile-0.5%acetic acid as the mobile phase in gradi-ent elution (0~5 min,10%A;5~27 min,10%~40%A;27.1 min ,10%A;27.1~30 min,10%A). The flow rate was 1.0 mL/min. The column temperature was 30℃.Carrier gas was nitrogen with the volume flow rate for 2.0 min/L, atomization temperature was 42℃, drift tube temperature was 65 ℃, gain was 5.Results The calibration curves of Gypenoside A, Ginsenoside Rb1, Gypenoside XLIX, Gypenoside XVII wre in good linearity over the ranges of 152.4~3048 ng(r=0.9996), 65.2~1304 ng(r=0.9998), 87.2~11744 ng (r=0.9998),11.3~226 ng (r=0.9995), respectively. the average recoveries were 98.65%(RSD of 1.95%),99.33%(RSD of 1.72%),99.67%(RSD of 2.28%),100.06%(RSD of 1.98%), respectively. content range of 9 group of gynostemma sample were that Gypenoside A for 6.92~22.63 mg/g,Ginsenoside Rb1 for 0~11.23 mg/g,Gypenoside XLIX for 0~13.24 mg/g,Gypenoside XVII for 0~4.16 mg/g. Conclusion The method to determine Saponin compounds in Gynostemma pentaphyllum is sensitive, accurate, separation effect is good, It has no interference, it can provide a basis as evaluation standard for quality of Gynostemma pentaphyllum.
