Integrating morphological and phytochemical studies on some selected taxa of Lamiaceae Lindl. and Verbenaceae Juss.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundLamiaceae and Verbenaceae are taxonomically sister families, belong to the order Lamiales. They are well known for their phytochemical constituents with bio-active properties, but considerable taxonomic difficulties in discriminating between the two families have been reported. The present study aims to explore the morpho-anatomical characters (stem and lamina) of 11 selected species bearing essential oils (EOs) by using the light microscope (LM), and to identify EO constituents in their aerial parts using gas chromatography-mass spectrometry (GC-MS), for taxonomic delimitation among these species. The essential oils of the species with the highest EO yield were tested in-vitro against a human hepatocellular carcinoma (HepG 2) cell line.
resultsThe macro- and micromorphological characters of the stem and lamina were recorded. From these characters trichomes, ground system, and vascular bundles were diagnostic at the species level. GC-MS analysis detected the existence of 160 constituents prevailed by monoterpenes and sesquiterpenes classes in all species under investigation except in Citharexylum spinosum L. A, monoterpenes (2.19%) and sesquiterpenes (0.3%). In-vitro bioassay of EO against HepG 2 revealed a significant effect, as evidenced by the IC
conclusionsThis work revealed that Lamiaceae and Verbenaceae families are closely related, showing fluctuation in the mutual morpho-anatomical characteristics of the studied species, however, EO analysis showed variation among these species.
