摘要 目的对雪菊进行生药学研究,为雪菊的基原鉴定提供理论基础。方法通过对雪菊性状以及组织构造和粉末显微特征进行观察,采用高效液相色谱对雪菊的主要成分进行分析,并建立其指纹图谱,从药材性状、显微、理化方面对雪菊进行生药学研究。结果雪菊性状特征,头状花序符合菊科共有特征,舌状花两色,上半部黄色,基部约1/2处紫褐色;粉末显微特征,黄色具刺的球形花粉粒、淡黄色至棕红色的分泌道碎片、乳头状突起的单细胞毛、花药基部细胞和花粉囊内壁细胞为其较明显的特征;建立了雪菊HPLC指纹图谱。结论雪菊性状特征符合菊科共有特征,与其同属植物剑叶金鸡菊和大花金鸡菊相比特征明显;研究补充雪菊生药学研究的不足,为雪菊系统的基原鉴定提供了参考。 Objective To conduct a pharamacognosical study on snow chrysanthemum( coreopsis tinctoria nutt.),and lay a theoretical foundation for its origin identification. Methods The properties,structure,and micro-characters of snow chrysanthemum powder were observed and described; the main components were analyzed, and finger-print was built with HPLC, aiming at analyzing snow chrysanthemum from property,microscopic,and physicochemical aspects. Results The macro-character and micro-characters of snow chrysanthemum are described as follows: the capitula of snow chrysanthemum is consistent with that of asteraceae species with two colors of the ray floret,yellow on the upper part,and purple brown in the middle of basal part. Powder under the microscope presents yellow spine spheroidal pollen grains,light yellow to brown red secretary canal scrap,papilla with simple cellular hair,basal part cell,and inner wall cells of pollen sac. The HPLC fingerprint was determined.Conclusion Snow chrysanthemum shares the common features with asteraceae species,and is different from Coreopsis lanceolate L,and Coreopsis grandiflora Hogg in the same genus. This study supplemented the gap in the pharacognosical study of snow chrysanthemum for origin identification.
