Linderangolides A-D, four new butanolides from the roots of Lindera angustifolia and their cytotoxic activity.

Four undescribed butanolides, linderangolides A-D (1-4), along with four known congeners, lincomolide A (5), (-)-epilitsenolide C2 (6), (-)-epilitsenolide C1 (7) and litseakolide H (8), were isolated from the roots of Lindera angustifolia. The planar structures of 1-4 were elucidated based on extensive spectroscopic analyses, the relative and absolute configurations of 1-4 were determined by the NOESY spectra and the comparison of calculated and experimental ECD. The cytotoxic activities of all isolated compounds were tested, 4 showed inhibitory activity against SGC-7 cells with IC value of 6.

Diversity of Culturable Endophytic Fungi in Crocus sativus and Their Correlation with Crocin Content.

The presence and diversity of endophytic fungi associated with host plants are important not just for host plant growth and defense, but also impact the production of medicinal secondary metabolites. However, the correlation between endophytic fungi and crocin production in Crocus sativus (CS) remains underexplored. Here, we explore the relationship between endophytic fungal diversity and crocin content among different CS tissues and field sites.

Application progress of immobilized biomembrane in the discovery of active compounds of natural products.

Natural products (NP) are an important source of bioactive compounds. Considering their complex matrix effects, the development of suitable methodologies for the quick identification and analysis of active substances in NPs played a significant role in controlling their quality and discovering new drugs. In recent years, the technology of immobilized biomembrane has attracted increasing attention, due to its advantages such as multitarget efficiency, accuracy, and/or time-saving compared with traditional activity-guided separation and ligand fishing methods.
