Goji berry\u00a0has been widely used\u00a0as medicine and food in China, it also has clear\u00a0chemical compositions and\u00a0pharmacological effect. However, goji berry leaves are not valued by people, people do fewer researches on their pharmacological effects,\u00a0Existing studies have shown that the chemical compositions\u00a0of\u00a0goji berry\u00a0leaves are similar to those of\u00a0goji berry\u00a0fruit,\u00a0goji berry leaves mainly contain\u00a0polysaccharide ingredients, polyphenols, vitamins and trace elements\u00a0which are higher than those of goji berry\u00a0fruit.<\/span><\/p>\n The main component of\u00a0polysaccharide ingredients\u00a0is goji berry polysaccharide, and the\u00a0content of\u00a0it that is higher than that in goji berry fruits is\u00a0up to 10.23%; as for the\u00a0structure, goji berry leaves are formed by neutral sugar, protein,\u00a0galacturonic acid and other ingredients,\u00a0and\u00a0neutral sugar\u00a0includes\u00a0Arabia\u00a0sugar,\u00a0rhamnose, galactose, glucose, mannose,\u00a0xylose and others.\u00a0Gong Guiping separated\u00a0and purified\u00a0LBLP5-A of\u00a0goji berry polysaccharides from\u00a0goji berry leaves, and the\u00a0relative molecular mass\u00a0is\u00a01. 13 \u00d7 105, the ratio of\u00a0relative molar rhamnose\u00a0,\u00a0Arabia sugar and galactoseis 0.5: 1.9: 1.0.<\/span><\/p>\n There are more than 100 kinds of diseases related to free radicals in the body,\u00a0and as for polyphenols,\u00a0especially flavonoids, they\u00a0have a significant effect on scavenging free radicals\u00a0antioxidant and antitumor.<\/span><\/p>\n Flavonoids are the main active substances in\u00a0goji berry leaves,\u00a0flavonoids\u00a0in goji berry\u00a0leaves are similar\u00a0to but high than that in goji berries, goji berry leaves\u00a0are rich in polyphenols in original plants,\u00a0and\u00a0are a new resource for the future food.\u00a0By using LC-PDA-ESI-MS\u00a0to analyze\u00a0phenolic compounds\u00a0inextracts\u00a0of goji berries, people found the main substances were\u00a0rutinquercetin,\u00a0kaempferol,\u00a0isorhamnetin, isoquercitrin,\u00a0luteolin,\u00a0kaempferol\u00a0-3-O-rutin\u00a0glycosides,\u00a0acacetin,\u00a0acacetin -7-O-, glucoside chlorogenic acid,\u00a0gentisic acid,\u00a0caffeic acid,\u00a0mono-caffeoylquinic acid,\u00a0dicaffeoylquinic acid, feruloylquinic acid\u00a0and\u00a0kaempferolrutinoside\u00a0etc. The rutin\u00a0which is\u00a0the most important ingredient\u00a0in goji berry leaves is\u00a0as\u00a0much\u00a0as 92% of total flavonoids.\u00a0In addition, different goji berry leaves contain different\u00a0chemical compositions, after identifying with the method of\u00a0HPLC-UV-MS, people find that\u00a0the content of\u00a0rutin\u00a0and quercetin\u00a0in\u00a0goji berry\u00a0leaves\u00a0are\u00a0higher than those\u00a0in\u00a0Ningxia\u00a0goji berries, and the gentisic acid,\u00a0caffeic acid\u00a0andkaempferol\u00a0can only be detected in goji berries.<\/span><\/p>\n After comprehensive analysis of GCMS\u00a0on\u00a0volatile components\u00a0in giji berry leaves, people found\u00a0terpenoids\u00a0in goji berry leaves, such as\u00a0ionol, mentholand\u00a03-hydroxy-7, 8-dehydro\u2014ionone.<\/span><\/p>\n People have severed\u00a0sitosterol, glucoside, gycosides of A and B sterols,\u00a0iso fucosterol,\u00a0campesterol, colesterin,\u00a0stigmasterol\u00a0and others.<\/span><\/p>\n Goji berry leaves contain many components which are higher than those in goji berries. Except the above components, there are more than 20 kinds of amino acids, vitamins, carotenoid and trace elements such as Fe Zn Ca Mg Se Mn P. The main amino acids in goji berry leaves are aspartic acid, glutamate, alanine and proline, and most of them are free. In addition, compared with oolong tea Longjing tea and Tie Guanyin tea, goji berry leaves contain higher contents of Fe and Zn.<\/span><\/p>\n","protected":false},"excerpt":{"rendered":" Goji berry\u00a0has been widely used\u00a0as medicine and food in China, it also has clear\u00a0chemical compositions and\u00a0pharmacological effect.
