摘　　要：分别测定了巨胚稻和相应非巨胚稻(对照)糙米的粗白质、粗脂肪、粗纤维、粗灰分等4种主要营养成分,17种氨基酸、9种矿物质、5种维生素和γ-氨基丁酸含量。结果表明:(1)同对照相比,巨胚稻糙米的粗蛋白、粗脂肪、粗纤维和粗灰分含量均有提高,平均增幅分别为11.14%、106.09%、42.21%和10.17%;(2)较对照,巨胚稻的17种氨基酸含量普遍提高,必需氨基酸总量提高2.52%～35.62%,氨基酸总量提高4.77%～37.09%;(3)巨胚稻的矿物质元素含量丰富,相比对照,其Ca、Fe、Zn、Mn、Mg、P、K、Na和Cd的平均含量分别提高了34.62%、45.08%、37.38%、37.09%、1.71%、5.39%、13.66%、13.46%和38.15%;(4)巨胚稻的VB1、VB2、VPP、VE和叶酸含量均高于对照,增幅为2.50%～214.81%;(5)巨胚稻糙米的功能成分γ-氨基丁酸(GABA)含量比对照增加,平均增幅达286.58%。巨胚稻富含各种营养成分,是一种高营养功能型的稻米品系。The contents of brown rice proteins, fats, crude fibre, ashs, amino acids, mineral elements, vitamin and GABA of giant embryo rice （ge-rice） and its original rice（CK） were analyzed. The results indicated that：（1）Compared with its original rice, ge-rice has an increase in the contents of brown proteins, fats, crude fibre and ash by 11.14%, 106.09%, 42.21% and 10.17%, respectively. （2）Most of the contents of 17 kinds of amino acids of ge-rice are higher than that of CK, and the essential free amino acid contents increases by 2.52% to 35.62%, the total amino acid increases by 4.77% to 37.09%. （3）The average contents of mineral elements Ca,Fe,Zn,Mn,Mg,P,K,Na and Cd is showed an increase of 34.62%, 45.08%, 37.38%, 37.90%, 1.71%, 5.39%, 13.66%, 13.46% and 38.15%. （4）The measured contents of vitamin V_ B1 , V_ B2 , V_ PP , V_ E and Folic acid rose by 2.50% to 24.81%. （5）The contents of GABA （γ-aminobutyric acid） in ge-rice is showed an increase of 286.58%. The giant embryo rice is a high nutrition and function type rice variety.
