Abstract:
Bionic extraction followed by atomic absorption spectrometry (BE-AAS) was used to determine the content and dissolution rate of calcium in rapeseed. Turnip seeds contained higher calcium content than the seeds of cucumber, bitter gourd, Perilla, black sesame, black pumpkin, grape, Cucurbitaceae and white gourd. The dissolution rates of black pumpkin and Cucurbitaceae seeds were almost 2 times higher than those of cucumber and bitter gourd seeds. The method exhibited good linearity over the concentration range from 3 to 21μg/mL, with a correlation coefficient of 0.9997. The average recovery for calcium was 103.58%, with a RSD of 1.27%. This method can allow accurate determination of the content of dissolution rate of calcium plant seeds. The seeds of the plants tested are abundant in calcium.
Key words: BE-AAS, plant seeds, calcium content, dissolution
