    Uji Aktivitas Antibakteriekstrak Metanol Berbagai Bunga Dahlia (Dahlia variabilis)
    (2015-04-11) Fata Morgana, Safari
    Phytochemical test explained that flower part from dahlia {Dahlia variabilis) contains terpenoid, fenolic and flavonoid. These groups have been reported that have potential as antioxidant, antimicrobial, etc. Methanol extract from dahlia were assayed for antibacterial activity by agar diffusion method. Methanol exfract at 10% concenfration (w/v) in ethanol absolute showed antibacterial activities, against Bacillus subtilis, Staphilococcus aureus and Escherichia coli. Strength of antibacterial activity for flower extract from dahlia were showed by Du Bandung againts Bacillus subtilis (15 mm), D? Bandung and Dii Berastagi againts Staphilococcus aureus (15 nmi), and D19 Malang againts Escherichia coli (15 mm).

    Uji Aktivitas Antimikrobial Dan Toksisitas Fraksi Etilasetat Dari Daun Tumbuhan Tabemaemantana sphaerocarpa Bl (Apocynaceae)
    (2015-07-03) Narullevi, Hadis
    The species of Tabemaemontana sphaerocarpa Bl member of Apocynaceae family, have been traditionally implemented in the treatment of antimalarial, bactericide, scabies medicine, ulcer, and strained (Eryanti et all., 2004). In vitro studies in this work presented some of the compounds such as terpenoid, alkaloid, and fenoiik. In 2005, Andrade et all., had been isolation of Tabemaemontana australis that included indole alkaloid as coronaridine(l), voacangine(2), voacangine hiroxyindolenine(3), rapicoline(4), ibogamine(5), ibogaine(6), ibogaline(7), and decetil-voacangine(8) and reported as anti inflamamoiy, anti-malarial, anti-HIV, and anti-cancer compounds. This study directs the attention to the antifungal, antibacterial, and anticancer from etilasetat fraction of Tabemaemontana sphaerocarpa Bl
