objectiveto study the optimum extraction process of total flavonoids from sorbus tianshanica rupr.

目的研究天山花楸中总黄酮最佳提取工艺。

The natural distribution, habitat and regeneration of Sorbus pohuashanensis were studied based on literature, specimen and on-site investigations. From the south to the north of China, most of S.

采用文献查阅、实物标本核对和实地调查相结合，对我国花楸树野生资源的分布特点、生境以及自然更新方式等进行调查研究。

Korean pine forest there, White Birch, Ash, walnut trees, such as Sorbus, there are many expensive medicines.

林中有红松、白桦、水曲柳、胡桃楸等树木，还有许多名贵的药材。

Using the young leaves of Sorbus folgneri as explants to induce callus, the best medium was 1/2MS+ 0. 5mg/L 6-BA+0.1 mg/L NAA+ 0. 5mg/L 2, 4-D, and the inducement rate could be up to 90%.

用石灰花楸的幼嫩叶片为外植体材料诱导愈伤组织，最适培养基为1／2MS+0.5mg／L 6-BA+0.1 mg／L NAA+0.5mg／L 2，4-D，诱导启动率达90％以上。

Mature embryos of Sorbus pohuashanensis were cultured on MS medium supplemented with different hormone combinations including BA, TDZ, IBA, 2,4-D and NAA.

以花楸成熟胚为外植体，在添加BA、TDZ、IBA、2，4-D、NAA组成的不同激素组合的MS培养基上培养。

The use of high-quality larch, pine, Sorbus wood, Ash Glulam the use of German Lei Mashi high-grade green paint, Germany Noto hardware products in full compliance with state environmental requirements and cater to modern people The natural qualities of the strong desire.

采用优质的落叶松、松木、楸木、水曲柳集成材；使用德国雷马士高档环保油漆、德国诺托五金件生产的产品完全符合国家环保要求，并迎合现代人对自然本色的强烈渴望。

The correlations between the phenotypic traits of fruits and seeds of Sorbus pohuashanensis and geographical and ecological factors were significant at latitude, altiturde, annual mean temperature and annual mean rainfall.

花楸树果实、种子性状与地理生态因子的相关分析表明，纬度、海拔、年均温、年降雨量与其性状呈显著相关。

Methodswith yield of total flavonoids and the sum integral relative peak area of total flavonoids in hplc chromatograms as the index, orthogonal experiment was carried to investigate factors of temperature, solid-liquid leaching rate, concentration of alcohol, which impact the yield of total flavonoids from sorbus tianshanica rupr.

方法采用正交实验，分别以比色法测定总黄酮提出率和高效液相色谱图谱中总黄酮相对积分峰面积为指标，考察提取温度、料液比、醇浓度对天山花楸叶中总黄酮提出率的影响。
