A report on the quality control parameters of aerial parts of Pluchea lanceolata (DC.) Oliv. & Hiern, Asteraceae

Abstract

RESUMO: "Relatório sobre os parâmetros de controle de qualidade das partes aéreas de Pluchea lanceolata (DC.) Oliv. & Hiern, Asteraceae." Pluchea lanceolata (DC.) Oliv. & Hiern, Asteraceae, é uma planta que tem sido usada como medicinal na Índia como um antipirético, analgésico anti-reumático e calmante. Este trabalho tem como objetivo estabelecer os padrões morfológicos e anatômicos e caracterizar o extrato(s) de P. lanceolata pela triagem fitoquímica preliminar como parâmetro de controle de qualidade para a matéria-prima.Unitermos: Pluchea lanceolata, controle de qualidade, físico-química, microscopia, fluorescência.ABSTRACT: Pluchea lanceolata (DC.) Oliv. & Hiern, Asteraceae, is a weed that has been used as an indigenous medicine in India as an antipyretic, analgesic, anti-rheumatic and nervine tonic. This paper aims at setting the morphological and anatomical standards and to characterize the extract(s) of P. lanceolata by preliminary phytochemical screening as quality control parameter for the raw material.

Morpho-anatomical characterization and DNA barcoding analysis of Pluchea indica (L.) Less.

“…The anomocytic stomatal cells consist of two guard cells and four subsidiary cells (Figure 3E). Similar result is also found in another genus Pluchea (King-Jones 2001), P. lanceolata (Khan et al 2010), and Asteraceae members (Tekin and Seyda 2021). Therefore, it is suspected that anomocytic stomata are the ancestor of all types of stomata since it also found in the fossil record of Angiosperms and other seed plants (Glas et al 2012).…”

“…The epidermis of the leaves is a solid cell construction shape from a square to a rectangle. The epidermis of P. indica leaves is also covered by trichomes as reported by Khan et al (2010) on P. lanceolata and Susetyarini et al ( 2020) on similar species. Mesophyll tissue in P. indica is dorsiventral type.…”

“…The cross-sectional anatomy of P. indica stem shows several tissues, namely epidermis, cortex, vascular bundles, cambium, and pith (Figures 2B1-2). The outermost layer is epidermis, which is rectangular and very densely packed as P. lanceolata (Khan et al 2010). In the layer below the epidermis, there is a cortex with an irregular shape and a thin cell.…”

“…In addition to function, xylem and phloem of P. indica L. are composed of different cells. Xylem consists of trachea, tracheid, wooden fiber, and parenchyma (Setjo et al 2004), while phloem comprises sieve tube, companion cells, and parenchyma (Khan et al 2010). Pith is the deepest tissue in the stem with the largest cell size among all cell types in the stem.…”
