我国主要野生沙棘叶片所含与健康有关的一些生物活性因子测定分析
Test and Analysis on Some Bio-Active Factors Relating to Health in Leaves of Main Wild Seabuckthorn Resources in China

为了掌握我国沙棘属植物主要种(亚种)叶片所含与健康有关的一些生物活性因子，对西藏、新疆、青海、甘肃等地野生的中国沙棘(Hippophae rhamnoides. ssp. sinensis)、云南沙棘(H. r. ssp. yunnanensis)、蒙古沙棘(H. r. ssp. mongolica)、中亚沙棘(H. r. ssp. turkestanica)、江孜沙棘(H. gyantsensis)、肋果沙棘(H. Neurocarpa)、西藏沙棘(H. tibetana)共7个种(亚种)，取叶样20个，采用气相色谱–质谱联用技术(GC-MS)测定了肌醇、甲基肌醇、白雀木醇、蔗糖、葡萄糖、果糖、苹果酸和Vc共8个生物活性指标，发现江孜沙棘叶片所含甲基肌醇、蔗糖、葡萄糖、果糖含量最高，云南沙棘叶片所含肌醇、苹果酸、Vc含量最高，蒙古沙棘叶片所含白雀木醇含量最高；而肋果沙棘叶片所含肌醇、蔗糖、葡萄糖、果糖含量最低，西藏沙棘叶片甲基肌醇和Vc含量最低，云南沙棘叶片所含白雀木醇含量最低，中亚沙棘叶片所含苹果酸含量最低。这些测定分析结果，将为不同种(亚种)沙棘在我国“三北”和西藏等地的资源建设和开发利用提供有关科学依据。
In order to learn the bio-active healthy factors relating of species and sub-species in China, the leaves of 20 samples from 7 species and sub-species, namely, Hippophae rhamnoides. ssp. sinen-sis, H. r. ssp. yunnanensis, H. r. ssp. mongolica, H. r. ssp. turkestanica, H. gyantsensis, H. Neurocarpa, H. tibetana, were collected from wild resources locations in Tibet, Xinjiang, Qinghai, Gansu, to analyze the inositol, methylinositol, L-quebrachitol, Sucrose, glucose, fructose, malic acid and Vc, with the method of GC-MS. The results showed that the contents of nositol, sucrose, glucose and fructose in leaves of H. gyantsensis were the highest, and the contents of inositol, malic acid and Vc in leaves of H. r. ssp. yunnanensis were also the highest, and the contents of L-quebrachitol in leaves of H. r. ssp. mongolica were the highest, too, while the contents of inositol, sucrose, glucose and fructose in leaves of H. Neurocarpa were the least, the contents of methylinositol and Vc of H. tibetana the least, and the contents of L-quebrachitol in leaves of H. r. ssp. yunnanensis and the contents of malic acid in leaves of H. r. ssp. turkestanica the least, too. The test results give scientific bases for the afforestation and development of the test species and sub-species of Hippophae in the Three-North and Tibet areas.
