Genus Castanopsis are native to tropical and subtropical Asia, comprising about 120 species. Some species from Castanopsis have been used as folk medicines in Asia. Phytochemistry investigations of the different plant parts of Genus Castanopsis have disclosed the presences of natural products including phenolics, terpenoids, steroids, and essential oils. Phenolics exist in Castanopsis species widely, particularly, triterpene ellagitannins were found to be potential chemotaxonomic marks of this geuns. The crude extracts and chemical constituents from Castanopsis have extensive biological activities, such as anti-inflammatory, anti-oxidative, antimicrobial, etc. In conclusion, the phytochemistry and biological activities of genus Castanopsis make it a promising source of natural products for drug discovery and development. This review collected the literatures published prior to 2023 on the traditional medicinal uses, phytochemistry, and bioactivties of the genus Castanopsis by searching from several scientific databases, such as Elsevier, Sci-finder, PubMed, Web of Science, CNKI, and Baidu Scholar. The main purpose of this systematic review is to provide the available information for relevant scholars to understand the progress in phytochemistry and biological activies of the genus Castanopsis and help the further development of this genus.

Castanopsis genus (Fagaceae) were rich in plant polyphenols and often used as medicinal plants. In this study, two new lignan dimer compounds with anti-inflammatory activity and four known compounds were isolated and identified from 80% methanolic extract of Castanopsis chinensis leaves. The structure determination supported by computational chemistry and extensive spectroscopic analysis.

Article Synopsis
- This study assembled a detailed genome for Castanopsis eyrei and sequenced genomes from 276 individuals across 12 Castanopsis species to explore genomic variation.
- The researchers found correlated genomic landscapes among species, with genetic diversity and differentiation linked to recombination rates and gene density, suggesting long-term evolutionary processes have influenced these patterns.
- The results indicated that both background selection and recurrent selective sweeps are important in explaining genomic variation, alongside extensive gene flow and adaptive introgression, which have shaped the genomes of hybrid species.

Objectives: Castanopsis is the third largest genus in the Fagaceae family and is essentially tropical or subtropical in origin. The species in this genus are mainly canopy-dominant trees, and the key components of evergreen broadleaved forests play a crucial role in the maintenance of local biodiversity. Castanopsis chinensis, distributed from South China to Vietnam, is a representative species.

This paper describes a new Russula species, R. brunneoaurantiaca, from India with morphological and molecular sequence (nrITS) data, field pictures of basidiocarps, and comparisons with close relatives. Russula brunneoaurantiaca has a brownish orange pileus with a mucilaginous surface, sub-decurrent lamellae that are white to pale orange, a white stipe that turns yellowish brown to brown when bruised, a strong, unpleasant smell, globose to subglobose basidiospores (5.
