【摘要】：目的:研究珊瑚狀猴頭菌的營(yíng)養(yǎng)成分及多糖對(duì)小鼠免疫功能的影響,為珊瑚狀猴頭菌的開(kāi)發(fā)提供理論依據(jù)。方法:按國(guó)標(biāo)法測(cè)定珊瑚狀猴頭菌中蛋白質(zhì)、脂肪、灰分、可溶性總糖、礦物質(zhì)元素、氨基酸。將48只昆明小鼠,雌雄各半,隨機(jī)分為對(duì)照組、低劑量組(100 mg/kg)、中劑量組(200 mg/kg)、高劑量組(400 mg/kg)4個(gè)組,30d后測(cè)定小鼠臟器指數(shù)、血常規(guī)、血清中抗體Ig G等。結(jié)果 :珊瑚狀猴頭菌干物質(zhì)中含粗脂肪6.44%,粗蛋白25.45%,灰分7.12%,可溶性糖44.24%;含有豐富的鐵、鈣、鎂、鋅等礦物質(zhì)元素;含18種氨基酸,其中8種必需氨基酸總量為6.92%。動(dòng)物試驗(yàn)表明,與空白組相比,中高劑量組的胸腺指數(shù)、脾臟指數(shù)、淋巴細(xì)胞百分率、單核細(xì)胞、T淋巴細(xì)胞百分率和Ig G均顯著或極顯著升高(P0.05或P0.01);高劑量組白細(xì)胞總數(shù)顯著升高(P0.05);中高劑量組的嗜中細(xì)胞均極顯著降低(P0.01)。結(jié)論 :珊瑚狀猴頭菌是一種蛋白含量高,礦物質(zhì)豐富,必需氨基酸齊全的食用菌。珊瑚狀猴頭菌多糖具有增強(qiáng)小鼠免疫功能的作用。
[Abstract]:Aim: to study the effects of nutritional components and polysaccharides on immune function of hericium Erinaceus in mice, and to provide theoretical basis for the development of Erinaceus coralis. Methods: protein, fat, ash, soluble total sugar, mineral elements and amino acids in coral hericium Erinaceus were determined by national standard method. Forty-eight Kunming mice, half male and half female, were randomly divided into four groups: control group, low dose group (100 mg/kg), middle dose group (200 mg/kg) and high dose group (400 mg/kg). After 30 days, the organ index, blood routine test and serum antibody Ig G were measured. Results: the dry matter of coral hericium Erinaceus contained 6.44% crude fat, 25.45% crude protein, 7.12% ash and 44.24% soluble sugar, rich in iron, calcium, magnesium, zinc and other mineral elements, and 18 kinds of amino acids, of which 8 essential amino acids were 6.92%. Animal experiments showed that compared with the blank group, the thymic index, spleen index, percentage of lymphocytes, monocytes, T lymphocytes percentage and Ig G in the middle and high dose group were significantly or extremely significantly increased (P 0.05 or P 0.01), the total number of leukocytes in the high dose group was significantly increased (P 0.05), and the neutrophils in the middle and high dose group were significantly decreased (P 0.01). Conclusion: Coral hericium Erinaceus is a kind of edible fungus with high protein content, rich in minerals and complete essential amino acids. The polysaccharide of hericium Erinaceus can enhance the immune function of mice.
