HPLC Separation of Fungicides in a Green Tea Matrix
Even though teas are known for containing polyphenols such as catechins, flavonoids and theaflavins, SIELC mixed-mode columns can be used to analyze a matrix from a commercial tea and retain target compounds. In this method, green tea was spiked with 0.005mg/ml of pesticides previously found in teas. Primesep 200 was used for it’s reverse-phase and acidic ion-pairing groups. Target compounds were retained and resolved from the majority of the tea matrix peak.

HPLC Separation of Agricultural Compounds Found in Tea
Tea has been known to contain residue of pesticides and fungicides such as picoxystrobin and pyrimethanil. We used Primesep 200, a reversed-phase column with weakly acidic ion-pairing groups to separate picoxystrobin, pyrimethanil and atorvastatin. A 15 minute method used to demonstrate retention control when adjusting ratio of organic to aqueous in the mobile phase. Baseline retention with good resolution was achieved.
