Abstract:
English Ivy or Hedera Helix is a multi-medicinal functioned plant in nature. Most coughmedicines in Vietnam were extracted from Ivy leaves because of its 5 main active components, & nbsp;in which 4 Saponins included Hederacoside C & nbsp;(predominance), & alpha;-Hederin, Hederacoside D, & nbsp;Hederasaponin B are responsible for eliminating congestion (breaking up the phlegm and & nbsp;mucus) and Flavonoid: Kaempferol 3-rutinoside plays the role of reducing inflammations [1]. & nbsp;This study aimed to develop a HPLC-PDA method to simultaneously and fast analyze these 5 compounds in materials and dietary supplements containing hedera helix extract in Vietnam & nbsp;market. After the simple preparation procedure, the analytes were separated by using a C18 & nbsp;column (150 mm & times; 4.6mm, 5 & micro;m) as stationary phase, and a mixture of 0.1% phosphoric acid & nbsp;and acetonitrile as mobile phase. The detection and quantification were in PDA detector at 205 & nbsp;nm. The method validation followed AOAC criteria. The calibration curves in the range of 0.5 & nbsp;- 200 mg/L for 4 saponins and 0.1 - 100 mg/L for the flavonoid with high correlation & nbsp;coefficient (R2 & gt; 0.9999). The MDL (0.03 - 0.15 mg/kg) and MQL (0.15 - 0.50 mg/kg); RSDr & nbsp;(%) for repeatability (1.01 - 3.90%) and RSDR reproducibility (1.25 - 6.89%); recoveries (91.3 & nbsp;- 106%) for 5 compounds satisfied the AOAC & nbsp;requirements. The method was applied & nbsp;successfully for determining the content of the analytes in 10 real samples including dried ivy & nbsp;extract powder, dried leaves, and some cough relief products purchased from markets in & nbsp;Hanoi. The levels of the 5 analytes were different in each sample in which Hederacoside C & nbsp;and & alpha;-Hederin account for the main proportions.
