Abstract

Lippia lupulina Cham. and Lippia pohliana Schauer are species of Verbenaceae used in folk medicine in the Brazilian Midwest. In order to identify the characteristics with taxonomic value that differentiate these species, the morphoanatomical characterization of the leaves and description of the chemical composition of the essential oils was carried out. The investigation of the anatomical characteristics of each species allowed the identification of different structural characters, related to the types of glandular and non-glandular trichomes, types of stomata, structural organization of the petiole's vascular system and the presence of sclereids in the petiole. Regarding the chemical composition of essential oil, in L. lupulina the main constituents were E-caryophyllene, caryophyllene oxide and dauca- 5,8-diene, while in L. pohliana, E-caryophyllene was the main constituent, followed by α-humulene and amorpha-4,7(11)-diene. Therefore, the results found have taxonomic value, as they allow the identification of species and help in the knowledge of the genus. And the characters studied contribute to future morphoanatomical, taxonomic and pharmacological studies.

枸杞精油的形态解剖特征及化学成分研究。和马鞭草科马鞭草

羽扇李。和Lippia pohliana Schauer是马鞭草科的一种，用于巴西中西部的民间医学。为了确定具有分类学价值的特征来区分这些物种，对叶片进行了形态解剖学表征，并对精油的化学成分进行了描述。通过对每个物种的解剖特征的研究，可以识别不同的结构特征，这些特征与腺毛和非腺毛的类型、气孔的类型、叶柄血管系统的结构组织以及叶柄中硬骨组织的存在有关。从精油的化学组成来看，羽扇豆的主要成分为E-石竹烯、氧化石竹烯和dauca-5，8-二烯，而朴丽花的主要成分是E-石竹二烯，其次是α-胡木烯和无定形-4，7（11）-二烯。因此，发现的结果具有分类学价值，因为它们可以识别物种，并有助于了解属。所研究的性状有助于未来的形态解剖学、分类学和药理学研究。

期刊介绍： FRONTEIRAS: JOURNAL OF SOCIAL, TECHNOLOGICAL AND ENVIRONMENTAL SCIENCE is an open-access, quarterly, peer-reviewed publication maintained by the Graduate Studies in Social, Technological and Environmental Science of the University Center of Anápolis (PPG STMA), with masters and doctoral degrees in Environmental Sciences. Fronteiras is an interdisciplinary journal that is driven by the belief that all types of knowledge must be available. It has as a target the researchers who dialogue in an interdisciplinary way with the theme "social and environmental science". The journal aims to publish original research, recognized rigorously for its theoretical-methodological, intellectual and scientific relevance. Fronteira has as the main theme of its publications the environmental science, aiming the scientific dissemination arising from the dialogues between the natural and human sciences and their connections with environmental science. Fronteiras: Journal of Social, Technological and Environmental Science has as its mission to publish and disseminate among the academic community, scientific manuscripts that are original and contribute to the promotion of multidisciplinary dialogues between the natural and human sciences and their connections with technological innovation, health as well as the environment.
