"Xiebai" is a medicine-food dual purpose Chinese native medicine,commonly seen in the diet of Chinese family andtraditionally used in the treatment of multiple cardiovascular,respiratory and digestive diseases such as angina pectoris,asthma,and diarrhea among others.The botanical origin of Xiebai is the fresh bulbs of either Allium chinensis G.Don(Jiaotou)or Allium macrosttemon Bounge(Xiaogensuan).To evaluate Xiebais nutritional value,we analyzed the contents of freeamino acids in both Allium chinensis G.Don and Allium macrosttemon Bounge using Hitachi L-8900 amino acid analyzer.It was found that both species contain a variety of free amino acids,and the percentage of essential amino acids over allfree amino acids is over 50%for Allium macrosttemon Boung,and over 35%for Allium chinensis G.Don.The essentialamino acids in Allium macrosttemon Boung mainly are threonine,arginine,phenylalanine,tryptophan,valine,histidine andlysine,and the ones in Allium chinensis G.Don are arginine,threonine,lysine,histidine and tryptophan.We compared thesimilarities and differences of amino acid composition among Xiebai,Garlic(Allium sativum)and Onion(Allium cepa),anddiscussed the relationship between amino acid composition and nutritional value in Xiebai.Our investigation provided thereference basis for Xiebais application in nutrition,health care and medication.

脂肪酶是一种重要的酶，它普遍存在于自然界，被广泛运用于精细化工、洗涤、医药、食品、造纸、皮革加工、纺织和饲料工业等领域，但其应用仍然受到天然脂肪酶分子的耐受性差、在应用条件下的催化活性低、新脂肪酶开发速度慢等因素的极大限制。因此，对现有脂肪酶进行分子改造使其更加符合人类的需求，成为了近几年的研究热点与难点。脂肪酶分子改造的常见方法有化学修饰、理性设计、定向进化等，其中在脂肪酶分子改造中引入偏最小二
