The high production of tropane alkaloids in hairy roots of Hyoscyamus reticulatus L. elicited by ZnO NPs in a bioreactor condition.
Article in Scientific reports, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 papers.
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
Chemical synthesis issue of tropane alkaloids and their lowest production rate along with their extraction costs has made use of new methods necessary to produce valuable pharmaceutical compounds. hairy roots induction end elicitation with biotic or abiotic elicitors such as nanoparticles can be used as a source for high production of worth metabolites compared to intact plants. Hyoscyamus reticulatus L. is a rich source of hyoscyamine and scopolamine, which are widely used in pharmaceuticals. Since the in this research, the effect of different concentrations (0, 25, 50, 75 and 100 mg/l) of zinc Nano oxide (ZnO NPs) as a stimulant on the growth rate, antioxidant enzyme activity and antioxidant activity, total phenol content (TPC), total flavonoid content (TFC) and tropane alkaloids in the H. reticulatus hairy roots was investigated in a bubble column bioreactor. The highest and the lowest amount of fresh weight (FW) (153.4 and 79.82 g) were recorded in 50 mg/l during 48 h exposure time and 100 mg/l during 72 h respectively. Also, ANOVA results showed that the interaction effect of concentration and exposure time was significant on guaiacol peroxidase (GPX) enzyme activity, TPC and TFC, antioxidant activity and alkaloid content (p < 0.01). HPLC analysis revealed that the highest amount of hyoscyamine and scopolamine (400 and 275.1 mg/kg of DW) were observed at ZnO NPs (75 mg/l) during 72 h respectively. According to the results, it can be said that the use of nano zinc oxide as a stimulant is an effective method for increasing tropane alkaloids in a bubble column bioreactor.
