Objective: To study the chemical constituents with antiviral action from Yinqiaosan on influenza virus.
Method: Constituents were isolated by different kinds of column chromatography and their structures were elucidated with chemical and spectral methods.
Result: Eleven chemical constituents were isolated and elucidated as arctiin, phillyrin, forsythiaside, liquiritigenin, liquiritin, genistein, formononetin, daidzein, glycitrin, 3,3',4-tri-omethlellagic acid and chlorogenic acid.
Conclusion: Genistein, daidzein, glycitrin and 3,3',4-tri-omethlellagic acid were isolated from Yinqiaosan for the first time.

One new azaphilone derivative () from in ordinary medium, one new phthalide derivative (), a microbial transformation product of ingredients by , a pair of new austdiol enantiomers (+)- and (-)-, one new epsilon-caprolactone derivative (), and one new ophiobolin-type sesterterpenoid () from the in host medium were reported. The structures were determined by spectroscopic analysis and single-crystal X-ray diffraction. Compounds - could completely inhibit the germination of rice seeds at 50 μg/mL, which is higher than that of the positive control.

The central nervous system (CNS) is not an immune-privileged compartment, but it is intimately intertwined with the immune system. Among the components shared by the two compartments is the complement, a main constituent of innate immunity, which is also produced centrally and controls the development and organization of synaptic connections. Complement is considered a doubled-faced system that, besides controlling the physiological development of the central network, also subserves synaptic engulfment pivotal to the progression of neurodegenerative diseases.

This study investigates the pharmaceutical potential both in vitro and in silico of ethanolic propolis extract from three Algerian regions namely TAH (Tahir-Jijel), ATH (Oued Athmania-Mila) and OZ (Oued Zhor-skikda). Twenty-three compounds were identified via HPLC‒DAD, with key constituents including caffeic acid, cynarin, chrysin, naringin, and hesperetin. Moreover, Antioxidant and anti-Alzheimer activities were assessed by multiple assays.
