“…To the best of our knowledge, the presence of rutin has not been previously reported for the V. sphaerocephala species analyzed in this work. Previous chemical investigations of V. sphaerocephala species have shown the presence of phenolic compounds such as bornyl ferulate, bornyl p -coumarate, tyrosol, icariside D 2 , and hyperin [ 18 ]. Identification of rutin in extracts should be helpful for further analysis.…”

Verbesina sphaerocephala A. Gray, like other wild plants of the genus Verbesina, has been used in herbal medicine. There is information for other species of the genus related to their phenolic content, antioxidant capacity, and isolation of bioactive compounds with antimicrobial activity. However, there are no reports for V. sphaerocephala, although it has an important presence in the state of Michoacán, México. In this study, the phenolic composition, quantification of rutin, and in vitro antioxidant and antibacterial activities of methanolic extracts from V. sphaerocephala leaves and flowers were determined. The results showed that all the investigated extracts have high phenolic and flavonoid contents. The flavonoid rutin was identified in all the extracts from V. sphaerocephala by high-performance thin-layer chromatography (HPTLC). The V. sphaerocephala extracts showed scavenging activity against DPPH• and ABTS•+ radicals (IC50 and 5.83 ± 0.50 and 0.93 ± 0.01 mg/mL, respectively) as well as relevant antioxidant capacity (51.05 ± 0.36 mg of ascorbic acid/g of dry tissue). The experimental results show that V. sphaerocephala extracts possessed a strong antimicrobial activity against Escherichia coli and Staphylococcus aureus bacteria. This research indicates that V. sphaerocephala could be considered as a potential source of natural compounds from the point of ethnopharmacological usage.

“…Verbesina species belong to the Asteraceae family and, as such, have been reported to be potential sources of lactones (mainly sesquiterpenes), which function as secondary metabolites and in turn show a wide variety of biological activities, while being useful precursors in the synthesis of natural products and compounds with insecticidal and parasiticidal activity [34]. Arciniegas et al [23] mention the presence of cadinenolide, a hydrocarbon that produces essential oils, in V. sphaerocephala. The effects of these oils on germination depend on the concentrations at which they are applied and may not result in stimulating effects.…”

“…Both V. sphaerocephala and V. fastigiata belong to the Asteraceae family and are endemic to western Mexico (i.e., the states of Jalisco, Michoacán, Nayarit, Guanajuato, and Guerrero) [20], where they are known by their common names of capitana and arnica capitaneja, respectively. However, the use of V. sphaerocephala or V. fastigiata is not widespread and only taxonomic, ethnobotanical information on either species is available [21], with the exception of recent chemical studies of V. sphaerocephala [22,23]. Therefore, we propose that the aqueous extracts of both species function as growth promoters.…”

The use of extracts derived from different plants has gained popularity as an alternative option to manage weeds and support phenological development in plants. One of the main problems facing agricultural production is the intensive application of chemical fertilizers that harm the environment. This study investigated the biostimulant effects of the aqueous extracts of Verbesinasphaerocephala and Verbesinafastigiata on the germination and growth of tomato (Solanum lycopersicum) and American cucumber (Cucumis sativus) seedlings. The aqueous extracts of both species of Verbesina were tested at concentrations of 0.5 and 1%. Seed germination and seedling development under nursery conditions were evaluated. The seed germination percentage was reduced in all treatments with the extracts of both Verbesina species when compared to that of the control treatment, which was considered an allelopathic effect. However, seedling growth in pots showed different behavior, with the extracts beneficially affecting certain agronomic variables, such as root and leaf length. The results suggest potential uses for V. sphaerocephala and V. fastigiata extracts, although a greater range of action may be experienced through the effects of certain molecules on weed growth. Additional studies with chemical approaches are necessary to better direct the uses and applications of Verbesina biomolecules, as they also functioned as growth promoters.
