Camellia oil saponins: Solid phase extraction and its effect on mice blood and organs

Abstract

In this study, the tea saponin extracted experiment was adopted to optimize extraction conditions. The solid phase extraction technique was used to extract saponin from camellia tea oil. Four macro-porous resins (DM301; NKA-9; HZ-841; S-8), two cation exchange resins (D001; 732), chitosan and diatomite, respectively, were used in a preliminary experiment; the HZ-841 macro-porous resin was determined as the optimal solid adsorbent material. The extraction conditions were; temperature 23.78 ºC; adsorption time 5.20 hour; liquid-to-solid ratio 12.54:1; predicted adsorption rate 20.20%; ethanol concentration 83.27%; eluent flow rate 1.18 mL/min; liquid-to-solid ratio 21.85:1; and the elution rate of tea saponin was calculated as 59.55%. The effect of tea seed oil saponin on mice blood and organs (liver, kidney, spleen and heart) was studied. The mice were randomly divided into six groups and fed for 90-days. Their weights were recorded every day. On the last day of the experiment serum ele­ments: Total cholesterol (TC), triglycerides (TG), low and high-density lipoproteins (LDL, HDL), as well as AST (aspartate aminotransferase), ALT (alanine aminotransferase) and total protein (TP) and organ (liver, kidney, spleen and heart) histopathologies were determined. The study results demonstrated that tea oil saponin expanded TC, TG, LDL and HDL. However, it generally increased ALT, AST activities and TP values compared to control groups. Tea oil saponin had no effect on organ tissue histopathology compared to control groups.
