Anatomical, phytochemical and histochemical study of Solidago chilensis Meyen

ABSTRACT Solidago chilensis Meyen, belonging to the family Asteraceae, is a plant native to South America and the only representative of the genus in Brazil. This species is popularly known as “arnica” and is used to treat bruises, muscle pain and inflammation. The objective of this work was to contribute to the pharmacognostic standardization of S. chilensis. Cross-sections were obtained, by freehand, for microscopic analysis of root, stem and leaf; for these parts of the plant maceration was also performed according to the method of Jeffrey. For the leaf were still made paradermal sections, scanning electron microscopy analysis, phytochemical and histochemical tests. Thus, it was determined anatomical features useful for diagnosis of the species which, together with identification of the chemical compounds and its histolocalization, provides support to their quality control.

【摘要】 智利一枝黄花（Solidago chilensis Meyen）隶属于菊科（Asteraceae），为南美洲原产植物，亦是该属在巴西的唯一代表物种。该物种俗称“山金车”，常用于治疗挫伤、肌肉疼痛及炎症。本研究旨在为智利一枝黄花的生药学标准化（pharmacognostic standardization）提供支撑。研究人员通过徒手切片法制备根、茎、叶的横切片以开展显微分析；同时针对该植物的上述组织，采用杰弗里法（Jeffrey）进行浸提处理。针对叶片样本，额外开展了平周切片制作、扫描电子显微镜（scanning electron microscopy）分析、植物化学与组织化学检测。最终明确了可用于该物种鉴定的解剖学特征，结合化合物鉴定及其组织定位结果，可为该物种的质量控制提供科学依据。
