Objective: To study the chemical constituents of Bidens pilosa var. radiata.
Methods: The constituents were separated and purified with silica gel column, and identified by physicochemical properties and spectral methods.
Results: Ten compounds were separated and identified as friedelin (1), n-tridecane (2), friedelinol (3), beta-sitosterol (4), 21 a-hydroxyfriedelan-3-one (5), stigmasterol (6), lupeol (7), stigmasterol-3-O-beta-D-glucopyranoside (8), eleosanole acid (9), friedelin-3beta-ol-27-oic acid (10).
Conclusion: Ten compounds are isolated from this plant for the first time.

Secretory canals are distributed among seed plants, and their diversity is concentrated in many families of angiosperms, while other internal secretory structures such as secretory cavities have been identified only in Rutaceae, Myrtaceae, and Asteraceae. Identifying and recognizing these two types of secretory structures has been complicated, mainly due to their structural similarities. In this study, the ontogeny of canals and secretory cavities in two species of Asteraceae are described and compared, to understand the structural differences between them and allow the establishment of more appropriate homology hypotheses.

Article Synopsis
- B. pilosa L. is an edible herb traditionally used for healing, and a recent study conducted a detailed analysis of its extract using advanced techniques like UPLC/T-TOF-MS/MS and GC-MS.
- The study found that unsaturated fatty acids (11.38%) and sterols (39.92%) were more prevalent in the extract than saturated fatty acids (8.69%) and hydrocarbons (6.6%), with oleic and palmitic acids being the most significant.
- The extract exhibited a concentration-dependent suppression of cell proliferation in cancer cell lines and showed potential as an inhibitor for certain enzymes, although safety toxicity assessments were missing, indicating a need for further research on its therapeutic effects.

Paris yunnanensis, also named as Rhizoma Paridis in the Chinese Pharmacopeia, is a perennial Chinese medicinal herb commonly grown in Southwest China. However, several viruses have been found infecting this plant in recent years. Using high-throughput sequencing (HTS) and Sanger sequencing, this study obtained the complete genome sequences of three capillovirus isolates and one potyvirus isolate.

Serpentine soils are characterized by high concentrations of heavy metals (HMs) and limited essential nutrients with remarkable endemic plant diversity, yet the mechanisms enabling plant adaptation to thrive in such harsh environments remain largely unknown. Full-length 16S rRNA amplicon sequencing, coupled with physiological and functional assays, was used to explore root-associated bacterial community composition and their metabolic and ecological functions. The results revealed that serpentine plant species exhibited significantly higher metal transfer factor values compared to non-serpentine plant species, particularly evident in Bidens pilosa, Miscanthus floridulus, and Leucaena leucocephala.
