摘要
为了评定我国沙棘属植物主要种(亚种)果实的β-胡萝卜素和Ve含量水平,用紫外分光光度计,对西藏、新疆、青海、甘肃等地8个种(亚种)的26个果实样品,测定了干基的果肉、籽和全果3个范畴的β-胡萝卜素含量和Ve含量,结果表明:西藏沙棘的干果肉、干籽、干全果的β-胡萝卜素含量和Ve含量均为最高,而柳叶沙棘除干全果Ve含量这一指标外,其余各个指标含量均为最低。西藏沙棘虽然各个指标含量都为最高,但目前尚无人工种植,加之果实产量较低,因此作为果实利用的前景暂不看好。而中国沙棘、中亚沙棘、蒙古沙棘3个亚种的适应性强,天然和人工资源都较多,果实产量、β-胡萝卜素含量和Ve含量都较高,因此建议在其适生种植地区科学布局,合理栽培,系统开发利用果品;而云南沙棘干果肉、干全果的Ve含量也很高,需要推动适宜区域的引种栽培。这4个亚种的沙棘将成为我国“第三代”沙棘果品的重要材料来源,有望对提高区域内人民健康水平、促进经济社会的高质量发展,起到十分重要的推动作用。
In order to analyze β-caroteneand Ve contents of main species and sub-species of Hippohae genus, 26 fruits samples from 8 species and sub-species,were collected from natural resources locations in Tibet, Xinjiang, Qinghai,Gansu, with the ultraviolet spectrophotometer method, which showed that the β-carotene and Ve contents of driedpulp, seeds and total fruits of H.tibetana were the highest among all the samples, and those of H. salicifolia were all the least exceptthe Ve content of dried total fruits. Though with the highest contents of twoingredients, H. tibetana was notsuitable for fruits development due to its low fruits yield and no artificialplantations, whereas for Hippophaerhamnoides. ssp. sinensis, H. r. ssp. turkestanica, H. r. ssp. mongolica, with strong adaptabilities,large scaled areas of both natural and artificial resources, high fruits yield,and contents of β-carotene and Ve inChina, should be put forward for a scientific layout, reasonable cultivationmeasures, and systematic development of their fruits. As for H. r. ssp. yunnanensis, with high contents of β-carotene and Ve, its introduction should be promoted in thesuitable areas for further fruits uses. The above mentioned four seabuckthornsub-species of the so-called “third generation fruit” will play an importantroles as an important resource of fruits to increase the health level ofChinese, promote the pace of quality development of economy and society in the seabuckthornplanting areas.
