Anticancer,antiobesity,and anti-inflammatory activity of Artemisia species invitro

OBJECTIVE： To investigate the anticancer, antiin flammatory, and antiobesity activity of methanol extracts of eight distinct species： Artemisia Stolon ifera （AST）, Artemisia Selengensis （ASE）, Artemisia .la ponica, Artemisia Montana, Artemisia Capillaris （ACA）, Artemisia Sylvatica （ASY）, Artemisio Keiskeana （AKE）, and Artemisia Scoparia （ASC） in vitro. METHODS： Antiproliferative activity was investigat ed in human breast cancer estrogen receptora pos itive T47D and negative HS578T cell lines exposed to the extracts at various concentrations （5200 mgl mL）for24, 48, and 72 h. For evaluating the antiin flammatory activity of the extracts, inhibition of ni trite synthesis was investigated in lipopolysaccha ride （LPS）stimulated cultures of macrophages cells exposed to 10, 50, 100, and 200 mglmL for 24 h. The antiobesity activity of the extracts was deter mined as triglyceride content and by a lipolysis as say in differentiated 3T3LI cells exposed to the extracts for 72 h at the same concentrations de scribed above. RESULTS： All extracts showed similar antiprolifera tive activity in a dose and timedependent man ner in HS578T cells. Although extracts at lower con centrations and shorter times stimulated growth of T47D cells, the antiproliferative effects of the extracts on T47D cells at higher concentrations （〉100 mg/ mL） for 72 h were significantly greater than those of HS578T cells. In case of antiinflammatory activi ty, some extracts （AST, ASE, ACA, and AKE） signifi cantly reduced nitric oxide production at higher concentrations in the presence of LPS compared with that in control cells. Antiobesity activity was showed with reducing lipid accumulation signifi cantly （〉50%） at concentrations above 100 mg/mL in most extracts （except AST and ACA）. Additional ly, AKE and ASC increased lipolysis by 11%24% compared with that in the control. CONCLUSION： Artemisia spp. demonstrates poten tial as bioactive food supplements.

OBJECTIVE: To investigate the anticancer, anti-inflammatory, and antiobesity activity of methanol extracts of eight distinct species: Artemisia Stolonifera (AST), Artemisia Selengensis (ASE), Artemisia Japonica, Artemisia Montana, Artemisia Capillaris (ACA), Artemisia Sylvatica (ASY), Artemisia Keiskeana (AKE), and ArtemisiaScoparia (ASC) invitro. METHODS: Antiproliferative activity was investigated in human breast cancer estrogen receptor-a positive T47D and negative HS578T cell lines exposed to theextractsatvariousconcentrations(5-200mg/ mL)for24, 48, and 72 h. For evaluating the anti-inflammatory activity of the extracts, inhibition of nitrite synthesis was investigated in lipopolysaccharide (LPS)-stimulated cultures of macrophages cells exposed to 10, 50, 100, and 200 mg/mL for 24 h. The antiobesity activity of the extracts was determined as triglyceride content and by a lipolysis assay in differentiated 3T3-L1 cells exposed to the ex-tracts for 72 h at the same concentrations described above. RESULTS: All extracts showed similar antiprolifera-tive activity in a doseand time-dependent manner in HS578T cells. Although extracts at lower concentrations and shorter times stimulated growth of T47Dcells,theantiproliferativeeffectsoftheextracts on T47D cells at higher concentrations (>100 mg/ mL) for 72 h were significantly greater than those of HS578T cells. In case of anti-inflammatory activity, some extracts (AST, ASE, ACA, and AKE) significantly reduced nitric oxide production at higher concentrations in the presence of LPS compared with that in control cells. Antiobesity activity was showed with reducing lipid accumulation significantly (>50%) at concentrations above 100 mg/mL in most extracts (except AST and ACA). Additionally, AKE and ASC increased lipolysis by 11%-24% compared with that in the control.CONCLUSION: Artemisia spp. demonstrates potential as bioactive food supplements.
