Two new triterpenesaponins, ilexsaponins G and H (1 and 2), together with six known triterpenesaponins (3-8), were isolated from the roots of Ilex pubescens. Their structures were elucidated on the basis of spectroscopic evidence and hydrolysis products. Those compounds showed inhibitory activities against two human colorectal cancer cell lines HCT 116 and HT-29.

Aromatherapy based on essential oil (EO) has been widely used for alleviating pain and intense where no compound EO reports its application on pharmacological effects. In order to explore the active pharmaceutical ingredients (API) and mechanism of a compound EO, a blend of Artemisia argyi, Boswellia carterii, Commiphora myrrha, Cinnamomum cassia, Zingiber oj-jicinale, and Ilex pubescens EO, in treating neck and shoulder pain (NSP). Network pharmacology hyphenated with mice model was employed to investigate.

Introduction: Myocardial ischemia-reperfusion injury (MIRI) remains a prevalent clinical challenge globally, lacking an ideal therapeutic strategy. Macrophages play a pivotal role in MIRI pathophysiology, exhibiting dynamic inflammatory and resolutive functions. Macrophage polarization and metabolism are intricately linked to MIRI, presenting potential therapeutic targets.

Hydraulic failure due to xylem embolism has been identified as one of the main mechanisms involved in drought-induced forest decline. Trees vulnerability to hydraulic failure depends on their hydraulic safety margin (HSM). While it has been shown that HSM globally converges between tree species and biomes, there is still limited knowledge regarding how HSM can adjust locally to varying drought conditions within species.
