Abstract
Common ragweed (Ambrosia artemisiifolia L.) is an invasive plant in Europe with spreading use in the contemporary folk medicine. The chemical composition of the above-ground parts is extensively studied, however, the metabolites of the roots are less discovered. By multiple chromatographic purification of the root extracts, we isolated thiophene A (1), n-dodecene (2), taraxerol-3-O-acetate (3), α-linoleic acid (4), (+)-pinoresinol (5), and thiophene E (7,10-epithio-7,9-tridecadiene-3,5,11-triyne-1,2-diol) (6). The 1H NMR data published earlier for 1 were supplemented together with the assignment of 13C NMR data. Thiophene E (6), which is reported for the first time from this species, exerted cytotoxic and antiproliferative effects on A-431 epidermoid skin cancer cells, whereas taraxerol-3-O-acetate (3) and α-linoleic acid (4) had slight antiproliferative effect on gynecological cancer cell lines. Thiophene E (6) and taraxerol-3-O-acetate (3) displayed antiproliferative and cytotoxic effects on MRC-5 fibroblast cells. Thiophene E (6) exerted weak antibacterial activity (MIC 25 μg/mL) on MRSA ATCC 43300, on Staphylococcus aureus ATCC 25923, Escherichia coli AG100 and E. coli ATCC 25922 both thiophenes were inactive. Although the isolated compounds exerted no remarkable cytotoxic or antiproliferative activities, the effects on MRC-5 fibroblast cells highlight the necessity of further studies to support the safety of ragweed root.

The Effect of Wheatgrass Lyophilizate on Blood Clotting Time in Rats. Sci Pharm 2021.

Abstract
Wheatgrass is widely used in the alternative medicine, however, there is a lack of clinical evidence to support its efficacy. Although based on its chemical composition, data from animal experiments and clinical trials, the use of juice and extracts of Triticum shoots seems to be safe, clinical reports point out its potential interaction with oral anticoagulants. The aim of our study was to assess the interaction of wheatgrass with warfarin in rats and to assess its flavonoid content. Three groups of animals were treated orally with wheatgrass, warfarin, or the combination of wheatgrass and warfarin for five days. Clotting assays were performed using platelet-poor plasma. Prothrombin time was determined by optical and mechanical coagulometers. Flavonoid content of wheatgrass was measured by HPLC. The effect of wheatgrass on prothrombin time was not confirmed. Co-administration of wheatgrass and warfarin did not result in diminished anticoagulant activity. Low amount of flavonoids was detected in wheatgrass juice, the total flavonoid content was 0.467 mg/100 g lyophilized juice powder. The previously reported rutin, quercetin and apigenin was not detected by us. Our results do not confirm the probability of interaction of wheatgrass with oral anticoagulants. However, the low flavonoid content of wheatgrass does not support its use as an antioxidant.

Abstract
Background In folk medicine, common chickweed (Stellaria media) has traditionally been applied for the treatment of hypercholesterolemia; however, there is no firm experimental proof to support the rationale of this practice. Therefore, we aimed to assess the efficacy and safety of Stellaria media) has traditionally been applied for the treatment of hypercholesterolemia; however, there is no firm experimental proof to support the rationale of this practice. Therefore, we aimed to assess the efficacy and safety of Materials and Methods. Adult male Wistar rats were divided into 3 groups. The (i) control group received standard laboratory chow, the (ii) hypercholesterolemic group received cholesterol-enriched diet, and the (iii) chickweed-treated hypercholesterolemic group received cholesterol-enriched diet and 100 mg/kg body weight Stellaria media) has traditionally been applied for the treatment of hypercholesterolemia; however, there is no firm experimental proof to support the rationale of this practice. Therefore, we aimed to assess the efficacy and safety of Results Cholesterol-enriched diet significantly increased serum total cholesterol, LDL- and HDL-cholesterol levels, but did not affect triacylglycerol concentrations. The addition of chickweed to the diet did not cause any significant change in serum lipid profile or body weight increase. Liver and kidney functions were unaltered and cardiac morphology and function were not changed due to Stellaria media) has traditionally been applied for the treatment of hypercholesterolemia; however, there is no firm experimental proof to support the rationale of this practice. Therefore, we aimed to assess the efficacy and safety of Conclusion Although chickweed does not seem to be toxic, our results do not support the rationale of its use in the treatment of hypercholesterolemia.
