    Duabanga grandiflora or known in Malaysia as Berembang Bukit, Megawasih, or Pedada Bukit, is a native plant of the Southeast Asian countries. In this study, the anti-viral properties of D. grandiflora were investigated.

    BACKGROUND: Garcinia species contain bioactive compounds such as flavonoids, xanthones, triterpernoids, and benzophenones with antibacterial, antifungal, anti-inflammatory, and antioxidant activities. In addition, many of these compounds show interesting biological properties such as anti-human immunodeficiency virus activity. Garcinia parvifolia is used in traditional medicine. Currently, the antiviral activity of G. parvifolia is not known.

    METHODS: This study was conducted to determine the effects of ethyl acetate (45 L Ea), ethanol (45 L Et), and hexane (45 L H) leaf extracts of G. parvifolia on the infectivity of pseudorabies virus (PrV) in Vero cells. The antiviral effects of the extracts were determined by cytopathic effect (CPE), inhibition, attachment, and virucidal assays.

    RESULTS: The 50% cytotoxicity concentration (CC50) values obtained were 237.5, 555.0, and

    Both wild-type virulent and mutant strains of pseudorabies virus (PrV) were used in this study. Mutants used were derived from the plaque purified strain PrVmAIP. A total of six drug resistant mutants, three bromodeoxyuridine (BUdR) resistant and three iododeoxyuridine (IUdR) resistant, respectively, were isolated and passaged in chicken embryo fibroblast (CEF) cells. The DNA of these PrVs were compared with the wild-type isolates by means of the restriction fragment pattern (RFP) findings produced with Bam HI, Kpn I, Hind III and Bgl II restriction enzymes (RE). Compared to the wild-type PrVs (PrV-VBA1-parental strain of PrVmAIP; PrV-VBA2; PrV-VBA3), the RFP of PrVmAIP showed the presence of mutations within the RE sites studied. Both PrV-VBA1 and PrV-VBA2 appeared to be closely related but their RFPs differed from PrV-VBA3. Significant differences either in the number, size or migrations of the DNA fragments could also be detected in the BUdR resistant strains. Even though different features of cytopathic effect (GPE) were observed in the IUdR resistant PrVs, the RFP findings remained identical. The PrVs studied showed considerable differences from the reference PrV (PrV-CD).
