Production of L-[3H]citrulline from L-[3H]arginine was measured to determine eNOS activity. 37℃暴露5min后测定L-[3H]精氨酸产生的L-[3H]瓜氨酸量来反映eNOS活性。
The elution rate was 98%, the purity of the product was 47.8% and the yield of citrulline in the whole process was 40%. 整个工艺过程洗脱率为98%25，产品纯度为47.;8%25，产品总收率为40%25。
It recently studied the herb Rhodiola rosea, also known as roseroot, and is due to evaluate the supplement citrulline malate. 为了评估补充物的瓜氨酸苹果酸，空军最近研究了中药红景天,亦称蔷薇根景天。
Citrulline therefore, not only supports detoxification pathways, but also supports NO production and a healthy cardiovascular system. 使用方法:每日服一至两次;每次服一至两颗.;两餐中间服
Because Citrulline is a precursor of Arginine, it provides a readily available source material for Arginine production, which in turn, can be used for the production of Nitric Oxide (NO). 这样的清理作用可以使身体在锻炼以后迅速恢复体力。
