This study aimed to investigate the protective effects of Teucrium polium (TP) on carbon tetrachloride (CCl) induced spleen, erythrocyte's oxidative stress, and genotoxicity in rats. TP was found to contain large amounts of polyphenols (150 mg GAE/G of dry plant) and flavonoids (60 mg QE/g of quercetin dry plant). The CCl (0.5 ml/kg) treated rats exhibited significant reductions in serum vitamin A (VA), vitamin E (VE) and total antioxidant status (TAS). Thiobarbituric acid reactive substances (TBARS) and conjugated dienes (CD) were significantly high in the CCl group compared to controls. Superoxide dismutase (SOD), catalase (CAT), and glutathione peroxidase (GPx) were significantly decreased in CCl rats. Cytogenetic trials revealed remarkable increases in the frequency of chromosomal aberrations (CAs) and sister chromatid exchange (SCE) following CCl administration. Pretreatment with TP prevented damages caused by CCl. Spleen characterised by necrosis was detected in CCl as compared to controls. Pretreatment with TP considerably decreased the perturbation.

Article Synopsis
- The Balkan Peninsula is a key area for studying plant diversity due to its ecological variety and the complexities of species taxonomies.
- A study of 57 populations using genetic and morphological methods revealed two main genetic clusters, with one cluster localized in the northwestern Dinarides and the other spread across the rest of the region.
- Genetic and morphological differences were more prominent in peripheral populations, while they diminished in regions where the clusters met, indicating a link between genetic structure and the area's geological and reproductive characteristics.

Teucrifarides A-D (1-4), four previously unreported neo-clerodane-type diterpenoids, combined with sixteen known analogs (5-20), were purified from Teucrium quadrifarium. The absolute forma of compounds 1-4 were determined via spectroscopic and ECD calculation methods, together with X-ray crystallography experiments. Among them, compound 1 possessed a 5,20-epoxy ring featuring a unique cage-like 12-oxatricyclo [5.
