[Abstract]:With the progress of the society and the development of the economy, people are increasingly concerned about their own health. The use of food to regulate human functions has become a means of fitness for the people. Anthocyanins are widely present in nature in plants in the water soluble natural pigment, antioxidant health function has been extensively studied, but there is still intake from Sibu, research on its preparation is very few, therefore, limit the application of anthocyanin preparation has broad market prospects. Black rice contains anthocyanins, which are mainly composed of -3-O- glucoside. In this paper, black rice anthocyanins are used as raw materials to develop black rice anthocyanin tablets. The preparation technology and quality standard of black rice are studied. In this paper, the following research results are as follows: (1) raw material properties: high humidity condition and strong light irradiation condition have great influence on the stability of anthocyanin in black rice. The influence of high temperature on its stability is relatively small. The time needed to decompose 10% of anthocyanins in black rice at room temperature is 210 days. The content of Fe~ (2+), Fe~ (3+) and Cu~ (2+) all decreased obviously, of which Fe~ (3+) had the greatest influence, and Mg~ (2+) had the effect of increasing stability. The acid condition is beneficial to the stability of black rice anthocyanin, and the lower the pH value of the solution, the more stable the black rice anthocyanin. The raw material itself illiquid (repose angle alpha =61.07 degrees, the density of pine pine =0.235, tap density is =0.407, compression degree =42.26%), is a "moisture". (two) preparation process: the best ratio of black rice anthocyanin and diluent is 1:1, the best ratio of starch to dextrin in diluent is 1:1.5, the best dosage of disintegrating agent crosslinked polyethylene, PVPP is 2%, and the best concentration of ethanol in wetting agent is 75%. The black rice anthocyanins forming preparation process are as follows: the black rice anthocyanins and other auxiliary material are 100 mesh nylon sieve, weighing according to the prescription, and will be the black rice anthocyanins diluent and disintegrating agent 1/2 mixed evenly, the tartaric acid dispersed in the amount of wetting agent, made of soft material, 20 mesh nylon sieve granulation, granule at 45 DEG C under the conditions of drying, drying after 20 mesh fine powder with whole grain, magnesium stearate and 1/2 disintegrating agent are mixed evenly and then with the particle mixing and tabletting. The black rice anthocyanin tablets prepared by the molding prescription and process are in accordance with the requirements of the Pharmacopoeia, and the formulation and preparation process are reasonable. (three) quality standard study: This product is a deep purple convex surface circular tablet with uniform size, uniform color and smooth surface. -3-O- glucoside was identified as a control product, and the identification method was high performance liquid phase method. The quality of the 3 batch of black rice anthocyanins were all qualified. The content of the -3-O- N=3947 glucoside in the preparation was determined by HPLC. The theoretical plate number is N=3947, repeatability is good (RSD=1.32%), and the sensitivity is high (the detection limit is 0.2 g/mL, and the limit of quantification is 1 g/mL. No delay before the peak), or smearing (trailing factor T=0.97), the degree of separation of R=2.411.5, completely separated. The method has high specificity and high precision (the precision of RSD=0.37%, the intra and inter day precision RSD=0.63%), accuracy can meet the detection requirements of complex components (recovery rate = 78.89%), and 12 hours stable (RSD=0.76%), the method is reliable and suitable for the determination of the preparation of cyanidin glucoside -3-O-. In addition, determination of total anthocyanins in black rice preparation by color value method, method of high precision (the precision of RSD=0.87%, the intra and inter day precision RSD=1.19%), accuracy can meet the requirements of detection (recovery =81.71%), and within 12 hours of stable (RSD=1.29%), the method is reliable and suitable for determination of the total anthocyanin content of the preparation. (four) determination of antioxidant activity in vitro: black rice anthocyanin material and its preparation all showed strong free radical scavenging ability in vitro and antioxidant reduction ability. The preparation process has no significant effect on the antioxidant activity of black rice anthocyanins. (five) the initial stability of the tablets: the influence of temperature on the stability of black rice anthocyanin tablets was the least, and the time required for decomposition of 10% at room temperature was 427 days. Under the condition of high humidity and strong light, the stability of black rice anthocyanin tablets was relatively low. Under accelerated test conditions, the stability of 3 batches of black rice anthocyanin tablets decreased slightly with time. To sum up, the preparation technology of black rice anthocyanin tablets is practical, the quality control method is scientific and reasonable, and it is accurate and feasible.
