| 中文摘要: |
| 采集湖南省9个城市2013年生产中广泛应用的稻谷样品75份，分离米糠并提取其中的油脂，采用高效液相色谱法分析不同品种米糠毛油中谷维素含量。结果表明：早籼稻米糠毛油中谷维素平均含量为1.79%，中晚籼稻的为1.57%，早籼稻较中晚籼稻的高；优质稻米糠毛油中谷维素平均含量为1.67%，普通稻的为1.65%，优质稻与普通稻的相近；优质早籼稻米糠毛油中谷维素平均含量（1.86%)较普通早籼稻的(1.75%)高，而优质中晚籼稻米糠毛油中谷维素平均含量（1.58%)与普通中晚籼稻的（1.56%)差别不大。 |
| 英文摘要: |
| Seventy-five rice samples that widely produced in 2013 were collected from nine cities in Hunan province, then the rice bran was separated to extract rice bran oil, and the contents of oryzanol in the different kinds of crude rice bran oils were analyzed by high performance liquid chromatography. The results showed that the average content of oryzanol in the crude rice bran oil from early indica rice was 179%, which was higher than 1.57% of middle-late indica rice; the average content of oryzanol in the crude rice bran oil from high quality rice was 1.67%, which was close to 1.65% of ordinary rice; the average content of oryzanol in the crude rice bran oil from high quality early indica rice (1.86%) was higher than that of ordinary early indica rice (1.75%), while there was no difference in the average contents of oryzanol in crude rice bran oils from high quality middle-late indica rice (1.58%) and ordinary middle-late indica rice (1.56%) . |
