Biflavonoid Profiling of Juniperus Species: The Influence of Plant Part and Growing Location

Applied Sciences
Biflavonoids are an important group of flavonoids found in Juniperus species, yet their distribution and accumulation patterns remain insufficiently explored. In this study, we applied a method for the simultaneous quantification of seven biflavonoids to

Phytochemical Screening of 45‐Million‐Year‐Old Colored Angiosperm Leaves Reveals Distinctive Chlorophyll‐Derived and Polyphenolic Pigments

Geobiology, Volume 24, Issue 1, January/February 2026.
ABSTRACT Present‐day angiosperm plants produce a plethora of metabolites including pigments that serve for important functions such as photosynthesis, protection against light, attraction of pollinators, and defense against microbes and herbivores. However, little is known about phytochemical constituents of ancient angiosperms, their distribution in ...

Safeguarding Spermatogenesis: Garcinia kola Extract and Kolaviron Effectively Ameliorate Testicular Toxicity in Rats Treated With Bleomycin, Etoposide, and Cisplatin Combination Therapy

Andrologia, Volume 2026, Issue 1, 2026.
Background Emerging evidence indicates that certain chemotherapeutic agents, particularly the bleomycin, etoposide, and cisplatin (BEP) regimen, exert deleterious effects on male reproductive function, including impaired spermatogenesis. Previous studies have demonstrated that Garcinia kola (GK) seed extract and its bioactive biflavonoid constituent ...

In-silico approaches to unravel the efficacy of naturally occurring C–C and C–O–C type biflavonoids towards the inhibition of MDM2–p53 interactions

Discover Chemistry
The p53 protein is essential for controlling the cell cycle and promoting apoptosis, which are critical processes in preventing tumor development. MDM2 acts as a negative regulator of p53 by facilitating its degradation, thereby diminishing its ability ...
