以甘肃省甘南藏族自治州碌曲县栽培和野生狭叶红景天为材料,分别对根茎(主根和侧根)的抗氧化能力、可溶性糖、总黄酮、酚类和红景天苷含量,以及挥发性组分进行研究.结果表明:狭叶红景天栽培根茎的自由基抑制率(I)、铁离子还原/氧化能力(FRAP),以及可溶性糖、总黄酮、酚类和红景天苷含量均显著大于野生根茎;栽培和野生根茎中均含有21种挥发性组分,相对含量较高的为苯乙酮、2-糠醛、棕榈酸等;与野生根茎相比,栽培根茎有15种组分的相对含量增加,主根中相对变化量较大的为3-羟基月桂酸、2,4-二叔丁基苯酚、亚麻酰氯等,侧根为2-乙酰呋喃、对羟苯基乙醇、丁子香酚等.栽培和野生侧根的I、FRAP值,以及总黄酮、酚类和红景天苷含量均显著大于主根.与主根相比,侧根有12种挥发性组分相对含量增加,变化量较大的为3-羟基月桂酸、10,13-十八碳二炔酸甲酯、对羟苯基乙醇等.栽培驯化后狭叶红景天根茎的抗氧化能力、主要活性物质含量及挥发性组分相对含量高于野生狭叶红景天,且侧根的品质更佳.
Taking Luqu County and Ganoderma lucidum as experimental materials, the antioxidant capacity, soluble sugar, total flavonoids, phenols and salidroside contents of rhizomes (main roots and lateral roots), and the volatile components The results showed that the contents of free radical inhibition (I), iron reduction / oxidation capacity (FRAP), soluble sugar, total flavonoids, phenols and salidroside in rhizomes of Rhodiola sachalinensis were significantly higher than those in wild There were 21 kinds of volatile components in the cultivated and wild rhizomes, and the relative contents were acetophenone, 2-furfural and palmitic acid. Compared with the wild rhizomes, the relative contents of 15 components Increase, the relative changes in the main root of the larger 3-hydroxy lauric acid, 2,4-di-tert-butyl phenol, linolenic acid chloride, etc., the lateral roots of 2-acetyl furan, p-hydroxyphenol, eugenol cultivation. And I, FRAP value of the wild lateral root, as well as content of total flavonoids, phenols and salidroside were significantly greater than the main root.Compared with the main root, lateral root 12 kinds of volatile components relative content increased, the larger the change of 3 -hydroxylauric acid, methyl-10,13-octadecadienoate, Hydroxyphenyl ethanol and the like. After the cultivation acclimation days narrowly antioxidant capacity Yehong Jing rhizomes, the main active substance content and the content of volatile components is relatively higher than that of wild Rhodiola, better quality and lateral roots.
