ความเที่ยง : เตรียมสารละลายมาตรฐานเ

Poise: the standard solution prepared Kerry CU noi Mitsubishi with various concentrations. : 5, 10, 15 and 20 mg/L, respectively, and the injection of HPLC systems, access to 10 μ L ponmit. Make a one-day trial in 7 (intra-day), and then repeat the experiment between วนั 7 (inter-day) the results to calculate a value S.D R.S.D maen (accuracy), or demand: extracts prepared by weighing (crude extract) 10 mg weight adjust volume 10 mL with ethanol, for example, the volume of pet health trends 500 μ L. Put into the bottles measure 4 volume 5 mL 1 bottle fine volume with ethanol. Sections 2, 3 and 4 bottles fill the solution come to rest the bases Kerry Mitsubishi 5, CU noi volume 10 and 15 respectively, and then adjust the volume L μ with full volume with ethanol is 1 mL injection of HPLC systems, access to the NA to volume of 10 L μ. Do repeat the experiment and the results 3. Calculate the percentage return (% recovery).

Reliability: Prepare a standard solution curcumin increases are concentrated in the 5, 10, 15 and 20 mg / L, respectively, leading to injection into the HPLC system at global Mia sqm 10 μL of the trial. Repeat the same day seven replicates (intra-day) and the experiment repeated between Nacional 7 repeatedly (inter-day) the effectiveness goes calculation of the SD or RSD accuracy (accuracy): prepared by weighing substances. extracts (crude extract) weights 10 mg adjustable volume 10 mL with ethanol and pipette sample volume of 500 μL put into bottles volumetric size 5 mL of four bottles at one adjust volume with ethanol. the bottle at 2, 3 and 4 Set the filling solution Kerr. Takumi Patapsco volume amounted to 5, 10 and 15 μL, respectively, and adjust volume with ethanol until the volume is full 1 mL then Naํ to injection into the HPLC system the volume of 10 μL of the experiment is repeated three repeat it. The result was to Calculate the percentage of recoveries (% recovery).
