Analysis of Active Ingredient Content of Ssanghwa Tea Bags according to Ssanghwa Extract Coating

This study was conducted to confirm the effect of increasing active ingredients by coating Ssanghwa tea bags with Ssanghwa extract. Coated Ssanghwa tea bags were manufactured by extracting Ssanghwa raw materials. Uncoated and coated Ssanghwa tea bags were extracted at 80 and 100°C for 3 minutes, and the contents of polyphenols, flavonoids, paeoniflorin, and decursin were analyzed. As a result of analyzing the content of polyphenols and flavonoids according to sample processing and extraction conditions, coated Ssanghwa tea bags showed the highest content of 17.44 mg /100g GAE(DW) and 1.46 mg/100g (+)-catechin when extracted at 100°C. The contents of paeoniflorin and decursin were analyzed using HPLC. When extracted from coated Ssanghwa tea bags at 100°C, paeoniflorin and decursin showed the highest contents at 0.08 and 5.32 mg/100mL, respectively. Coated Ssanghwa tea bags are expected to increase their physiological activity by increasing their active ingredients and expanding their usability as an easily usable product.
