[Method] A total of 60 volunteers were selected, and each of them consumed two bags of instant asparagus powder （24 g） once a day for 60 consecutive days. Then, the sleep quality of the volunteers was evaluated. At the same time, the safety indices and insomnia-related endocrine indices were determined. [Result] Instant asparagus powder significantly increased the sleep time of sleep disorders from 5.1 to 6.1 h, shortened the time to fall asleep from 50.4 to 25.3 rain, and reduced the time to fall asleep after being awake from 46.5 h to 19.5 h. The differences before and af- ter the consumption of instant asparagus powder were significant （P〈0.05）. The sat- isfaction of sleep quality was high. Instant asparagus powder had good safety with- out liver and kidney function influence. Instant asparagus powder could reduce the levels of cortisol and norepinepthrine and increase the levels of serotonin and dopamine. [Conclusion] Instant asparagus powder could improve the quality of sleep, characterized by safety and effectiveness. The sleep quality-improving effect of in- stant asparagus powder might be related to the regulation of HPA axis or the regu- lation of serotonin secretion.展开更多
