This study was conducted to carryout preliminary phytochemical analysis and in vitro antimicrobial activities of aqueous and ethanolic root and stem bark extracts of Ficus sycomorus. Qualitative phytochemical analysis for tannins, saponin, terpenoids, flavonoids, alkaloids, glycosides, steroids, phenols, and reducing sugar was done using standard methods. The antimicrobial activities of the extracts were tested against four micro- organisms; Escherichia coli, Staphylococcus aureus, Shigella dysentrae, and Salmonella typhi. Agar well diffusion method was used for the antimicrobial studies. Phytochemical screening of both root and stem bark aqueous extracts showed the presence of tannin, saponin, terpenoid, flavonoid, alkaloids,  glycoside, steroid, reducing sugar, and phenol. Glycoside was not detected in both the aqueous and ethanolic extracts of the root bark. The result of the antimicrobial studies showed that the aqueous root extract have higher antimicrobial activity ranging from (2-12 mm) on the tested microorganisms than aqueous stem bark extract (3-9 mm), while for ethanol extract both stem and root bark extract has almost the same effect or antimicrobial activity on the tested pathogens ranging from (2-15 mm) which is having higher activity compared to the aqueous extracts. The Minimum inhibitory concentration (MIC) and Minimum bactericidal concentration (MBC) of both the extracts were found to be 50 mg/mL and 100 mg/mL respectively.  From this study, it can, therefore, be concluded that the root and stem bark extract is a potential antimicrobial agent which support the claim of the traditional users of this plant in herbal medicine for the treatment of diseases that are of microbial origin.

To investigate the protective effects of galangin on liver toxicity induced by carbon tetrachloride (CCl4) in mice. Mouse hepatotoxicity model was established by intraperitoneal injection (i.p.) of 10 ml/kg body weight CCl4 that diluted with corn oil to a proportion of 1:500 on Kunming mice. The mice were randomly divided into five groups named control group, model group, and 1, 5, and 10 mg/kg galangin group. The levels of alanine aminotransferase (ALT) and aspartate aminotransferase (AST) were analyzed by ELISA. Liver histopathological examination was observed via optical microscopy. The levels of superoxide dismutase (SOD), malondialdehyde (MDA), glutathione (GSH), and glutathion (GSSG) were analyzed to assess oxidative stress. Finally, western blot assay was carried out to analyse the expression levels of total AMP-activated protein kinase (AMPK), phospho-AMPK (p-AMPK), total liver kinase B1 (LKB1), and phospho-LKB1 (p-LKB1). Compared with the control group, in the model group, the levels of AST, ALT, MDA, and GSSG increased significantly ( p < 0.01); the activity of SOD and GSH decreased significantly ( p < 0.01); and the histopathological examination revealed liver necrosis. However, treatment with galangin (5 and 10 mg/kg) significantly reversed these CCl4-induced liver damage indicators. Furthermore, treatment with galangin (10 mg/kg) significantly increased the p-AMPK and p-LKB1 expression levels ( p < 0.01). This study supports the hepatoprotective effect of galangin against hepatotoxicity, perhaps occurring mainly through the LKB1/AMPK-mediated pathway.

Morus alba (white mulberry) is native to the northern part of Korea and popularly used as a traditional medicine due to its numerous health benefits against human’s disease. However, the possibility that M. alba may also affect the cardiovascular system remains unexplored. This study sought to investigate the vascular protective effects of the root bark extract of M. alba (MAE). Vascular reactivity was performed in organ baths using isolated rat thoracic aorta, while platelet derived growth factor (PDGF) induced proliferation and migration of vascular smooth muscle cells (VSMCs) were studied by 3-(4,5-dimethylthiazol-2-yl)-5-(3-carboxymethoxyphenyl)-2-(4-sulfophenyl)-2H-tetrazolium (MTS) and wound healing assay, respectively. MAE evoked a concentration dependent vasorelaxation following endothelium-dependent pathway. However, vessel relaxations in response to MAE were markedly reduced after endothelium removal; treatment of endothelial nitric oxide synthase inhibitor, guanylyl cyclase inhibitor, and nonspecific potassium channel inhibitor, however, was not altered by cyclooxygenase inhibitor. Furthermore, MAE also significantly blunted contractile response to vasoconstrictor agent, phenylephrine. Taken together, the current evidence revealed that MAE is a potent endothelium-dependent vasodilator and this effect was involved in, at least in part, nitric oxide cyclic-guanosine monophosphate (NO-cGMP) pathway in combination with potassium (K+) channel activation. Moreover, MAE inhibited proliferation and migration of VSMCs induced by PDGF. Therefore, MAE could be a promising candidate of natural medicine for preventing and controlling cardiovascular diseases linked with endothelial dysfunction.
