Two kinds of flavonoids in water extracts , water - extraction and alcohol precipitation , alcohol extracts were found by paper chromatography . they were separated and purified by thin - layer chromatography , one of which was primarily identified by uv as 4 “ , 5 - dihydroxy - flavonol etherification or 4 “ , 5 , 8 - trihydroxy - flavonol etherification 水提物、水提醇沉物、醇提物等3種提取物紙層析結果顯示有兩種黃酮類化合物，經薄層層析分離純化，并進行紫外光譜分析，初步測定其中一組分為4 ， 5 -二羥基黃酮醇醚或4 ， 5 ， 8 -三羥基黃酮醇醚。 |

At the surface of the pollen grains there are three types of aperturates , including three porates type , three colpates type and three porate - colpates type ; and four types of sculpture , namely , reticulate , striate , striate - reticulate and verrucate . the upper epidermal cells of the leaves of 12 species plants are detected with hpias - 1000 image analytic system through the treatment of binarization , and the experimental methods are proved stable . the results indicated that the waviness of the anticlinal walls ( sfc ) and the ratio of the feret ' s diameter ( slf ) of the epidermal cells of the middle lamina in the third node of leaves starting from the lowerest part of the stem have a relative constant range and could distinguish from each other . oieanolic acid , l , 5 , 8 - trihydroxy - 3 - methoxyxanthone and swertiamarin are separately detected on the tlc , and the different chromatogram of various plants can be considered as characters of identification . the contents of oleanolic acid in 12 species of plants are determinated by hplc , but among the different plants and botanical organs their contents are different , and the highest content in flowers 本文對川鄂產獐牙菜屬藥用植物資源進行了野外調查、標本采集和鑒定，對12種干燥藥材的性狀進行了描述，提供了可以鑒別的特征。通過掃描電子顯微鏡觀察的12種本屬藥用植物的花粉粒均為單粒花粉，萌發孔有3孔型， 3溝型和3孔溝型三種類型；表面紋飾包括網狀紋，條狀?網狀紋，條狀紋和瘤狀紋四種類型。用hpias ? 1000高清晰度彩色病理圖文分析系統對葉片上表皮細胞作圖像分析，并進行方法學研究，結果表明，同種植物莖上第3節葉片中段主脈和第1側脈之間葉上表皮細胞垂周壁彎曲程度sfc值和細胞縱、橫向直徑的比值slf值，種間有顯著差異，每種都有相對恒定范圍值。 |
