Conventional and molecular pharmacognostic characters integrated with chemical profiles of five Piper plants in the Thai herbal pharmacopoeia and their admixture/adulteration/substitution situations in Thailand.

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
The morphological and microscopy were combined with DNA-barcoding, together with rapid TLC for the characterization of Piper betle (PB), P. nigrum (PN), P. retrofractum (PR), P. sarmentosum (PS), and P. wallichii (PW), five medicinal Piper plants announced in the Thai Herbal Pharmacopoeia (THP). The authentic plants collected from various locations and voucher Piper products bought from commercial sites in Thailand were studied. The reproductive parts of authentic plants were subjected to ensure their morphological characters. Using sequencing analysis and genetic divergence for analyzing discriminatory performance, ITS2 was selected from eight candidate DNA markers to authenticate the origin of Piper crude drugs together with microscopic and TLC profiles for examining their characters, admixtures, adulterants, and substituents. PB and PR exhibited unique characters of the species, with no admixture, adulteration, and substitution. PN showed no variable characters of morphology and genetics. However, the microscopy could illustrate some commercial products of PN sold in Thailand have been adulterated with rice starch and roasted rice. In the herbal trade, PS has been sold in the form of mixed leaf, root, and stem more than the isolated part, but there is no variable character of the species. PW has shown more than one character of species explained by microscopic, chemical components, and genetic data. In conclusion, the conventional and molecular pharmacognostic data combined with chemical profile of authentic five Piper plants could be applied to indicate the plant origin and clarify the situations of admixture, adulteration, and substitution of the commercial Piper products launched in Thailand.
