We investigated the cytotoxic and antitumor effects of nine leaf extracts from Artemisia dracunculus (Tarragon). Five extracts were obtained using different organic solvents and four by supercritical CO2. The cytotoxic effects were expressed as IC50 in 100, 80, 80, 100, and 80 μg/mL by respective solvents: hexane, ethyl acetate, acetone, ethanol, and acetonitrile in L5178Y lymphoma cells. For supercritical CO2 extract A, IC50 was 100 μg/mL; for extracts C and D, IC50 was 150 μg/mL. The antitumor activity was assessed through a tumor growth inhibition test that measured ascites fluid volume and tumor cell counts of BALB/c mice (2 × 10(4) cells L5178Y i...

Obesity is the largest and fastest growing public health catastrophe in the world affecting both adults and children with a prevalence impacting more than one-third of United States (US) adult population. Although the long-term solution lies in lifestyle changes in the form of dieting and exercise, intervention is required for those who are already obese. Unfortunately, treatment options remain quite limited due to associated side effects of conventional therapeutics. As a natural alternative, in this study we describe the beneficial effect of a standardized composition (UP603) comprised of extracts from Morus alba, Ilex paraguariensis, and Rosmarinus officinalis in improving metabolic disorders in high fat diet (HFD) and high fat & high fructose diet (HFFD) induced obese C57BL/6J mice...

Hyperglycemia leads to diabetes and its diabetic complications. In this study, we investigated the synergistic effects of luteolin and fisetin on proinflammatory cytokine secretion and its underlying epigenetic regulation in human monocytes exposed to hyperglycemic (HG) concentrations. Human monocytic cells (THP-1) were cultured under controlled (14.5 mM mannitol), normoglycemic (5.5 mM glucose), or HG (20 mM glucose) conditions in the absence or presence of the two phytochemicals for 48 h. Whereas HG conditions significantly induced histone acetylation, nuclear factor-kappa B (NF-κB) activation, interleukin 6, and tumor necrosis factor-α release from THP-1 cells; combination treatments with the two phytochemicals (500 nM fisetin, and l μM and 500 nM luteolin) suppressed NF-κB activity and inflammatory cytokine release...
