Aeollanthus suaveolens Mart. ex Spreng belongs to Lamiaceae family, and in the Amazon this species is cultivated by natives’ people, this medicinal plant is popularly known as Catinga-de-mulata, being used by the population for general pain treatment. The present study analyzed the effects of light intensity on the anatomy, secretory structures, histochemistry and composition of essential oil of leaf and stem of A. suaveolens. The anatomical structure were observed in response to two light intensities, namely 50% (half shade, HS) and 100% (full sun, FS) light. Histochemical analyses were performed to detect lipids, essential oils, alkaloids, phenolic compounds, sesquiterpene lactones, mucilage, and tannins. Secretory structures were observed under a scanning electron microscope. The results obtained in the present work indicate that the light intensity can affect the histochemistry and structures of A. suaveolens. Cross sections of the leaves and stem revealed glandular trichomes on both leaf surfaces as well as the stem surface. Essential oil was detected by histochemical analyses in all types of secretory trichomes. These anatomical and histochemical responses suggest modifications to protect the photosynthetic apparatus from excess light, in addition we note that in the chemical composition of the essential oil the class of hydrocarbons sesquiterpene prevailed.

风神。ex Spreng属于唇形科，在亚马逊地区，该物种是由当地人种植的，这种药用植物被俗称为Catinga-de-mulata，被人们用于一般性疼痛治疗。本研究分析了光强度对su菜叶和茎的解剖结构，分泌结构，组织化学和精油成分的影响。。响应于两种光强度，即50％（半阴影，HS）和100％（全日照，FS）光，观察到了解剖结构。进行了组织化学分析，以检测脂质，香精油，生物碱，酚类化合物，倍半萜内酯，粘液和单宁。在扫描电子显微镜下观察分泌结构。目前的研究结果表明，光强度可以影响藜的组织化学和结构。。叶片和茎的横截面在叶片的两个表面以及茎表面均显示出腺毛。通过组织化学分析在所有类型的分泌毛状体中检测到精油。这些解剖学和组织化学反应表明，可以进行修饰以保护光合作用装置免受过量光的影响，此外，我们注意到在香精油的化学成分中，倍半萜类碳氢化合物占主导地位。
