In recent years, some departments such as “Institute of Medicinal Plant Development, Chinese Academy of Medical Science” has analyzed the nutritional ingredients contained in Opuntia dillenii in parallel with consecutive reports of some journals and special literatures. This paper summarized the results mentioned above.

In recent years, some departments such as “Institute of Medicinal Plant Development, Chinese Academy of Medical Science” has analyzed the nutritional ingredients contained in Opuntia dillenii in parallel with consecutive reports of some journals and special literatures. This paper summarized the results mentioned above.
The nutritional ingredients contained in Opuntia dillenii can generally be induced several types as follows: 1.Proteins and amino acids; 2. fats; 3.Sugars (usually polycarbohydrates being composed of L-arabinose and D-galactose); 4.Vitamins; 5.Trace elements; 6 Organic acids.
Protein are the foundation of lives for neither the basic structures of the prokaryotic microorganisms nor those of the eukaryotic microorganisms need proteins. They are not only the fundamental components of all the protoplasts, but also the fundamental components of various enzymes being the biological catalyzers. Meanwhile, the combination of proteins, fats, and sugars is the most important energy-supplied substance in bio-actions, frankly speaking, lives can not survival without proteins. Proteins are composed of several tens of amino acids, among them more than 20 amino acids present in human bodies. Part of the amino acids can not be synthesed by the human bodies or they can be synthesed with extremly trace quantities and must be intaken from food, which are called “essential amino acids(EAA)”. Modern scientific researches showed that human EAA included leucine, isoleucine, lysine, methionine, phenylalanine, threonine, tryptophan, and valine, histidine is also essential to babies. The presence of tyrosine in human bodies can save phenylalanine, thus these two amino acids are called “semi-essential amino acids”. Recent researches also found that 2-aminoethanesulfonic acid was also essential to human bodies, which is specially important for the development of baby’s intelligence. 12 amino acids species are generally called “human EAA”, while other amino acids such as glycine, hydroxyproline, alanine, serine, cystine, cysteine, aspartic acid, asparagine, glutamate, glutamine, tyrosine, arginine, proline, etc, are generally called ” non-essential amino acids”., Amino acids are extremly easy to be digested and absorbed by human bodies for they are water-soluble, thus food contained rich amino acids is considered as high nutritional value food. The analysis of Opuntia dillenii’s ingredients showed that Opuntia dillenii contained 10 EAAs of 12 human EAAs, and each human EAA was contained in a fairly large content ranging from >10 to >20 mg/100 g, this is just its value for human’s health.
Fats are essential components in human bodies and often prensent in cell membrane and brain & peripheral nerve tissues in the forms of various phospholipids and glycosphingolipids. They can promote the adsorption of ester-soluble Vitamin A, Vitamin D, Vitamin E, Vitamin V, and carotene. Additionally, neutral fats are stored in bodies providing the energy resource for bio-action. Therefore, fats of suitable content are benefit for health. However, if fat content in the body excesses the standard they are harmful for health. Opuntia dillenii contains little fats, and 100 g fresh Opuntia dillenii only contains 210 mg fats, thus it belongs to low-fat health-caring food.
