Plants used as antimicrobials in the treatment of infectious diseases in folk medicine are regularly evaluated in different Laboratories. And, the processes of evaluation of antifungal susceptibility are often different to one laboratory to another. This study was undertaken in the goal to compare parameters obtained (MIC and MFC) with two antifungal susceptibility testing. The first one is Agar slant double dilution tubes method (M1) and the second is disc diffusion method /broth dilution according document CLSI M38 -A2 supplemented to 2% glucose (M2). Ethanol (EtOH 70%), Methanol (MeOH) and n-Hexane (n-HexTG) extracts of leaves of Tectona grandis have been tested in comparison to Itraconazole against two clinicals strains of Aspergillus fumigatus 896/AB and Aspergillus flavus 1006/OM isolated to HIV patients. Results showed that on A. flavus, agar slant method (M1) gave MIC ranging between 200 µg/mL and 800 µg/mL while disc diffusion meth/broth dilution (M2) showed growth inhibition between 100 µg/mL and 400 µg/mL. On A. fumigatus, inhibition was observed between 200µg/mL and 400 µg/mL with M2 in contrary M1 gave MIC located between 400 µg/mL and 800 µg/mL. For each strain tested, according method M2, MIC and MFC are identical and with method M1, these parameters were different. Evaluation of Itraconazole on each strain gave with M2, MIC= 50 µg/mL while inhibition has been showed at 100 µg/mL and 200µg/mL with M1. Also considering extracts, hydroalcoholic extract of T. grandis (EtOHTG) showed antifungal susceptibility testing less 2 to 4 efficiency than Itraconazole. Disc diffusion method/broth dilution (M2) according CLSI M38-A2 to evaluate Tectona grandis antifungal susceptibility is the process of evaluation which allo wed having lo west antifungal parameters (MIC and MFC) on A. flavus and A. fumigatus.

Aims: To profile and address matters surrounding ochnaflavone (1), derivatives and analogues. Methodology: Papers concerning ochnaflavone, derivatives and analogues were accessed from search engines such as google scholar and pubmed. Results: Ochnaflavone and derivatives are compounds bearing ether linkage between the two Brings of the two flavonoid moieties. These compounds are known to possess potent biological activities such as anti-inflammatory, anticancer, anti HIV and antimicrobial. Conclusion:In this paper, an overview summary of ochnaflavone, derivatives and analogues from past to present is presented. Thus, the paper provides a sense of focus to researchers; seal breaks the unattended matters, and therefore, spearheads new research areas concerning these compounds.

Brackenridgea zanguebarica Oliv. is among the most popular and frequently used tree species in Vhembe District, Limpopo Province of South Africa. However, the increasing illegal overexploitation coupled with the reproductive inefficiency have caused a severe depletion of this plant population bringing the species on the verge of extinction. B. zanguebarica, commonly known as "yellow peeling plane" and locally known as "Mutavhatsindi" is an important tree usually used both for medicinal and magico religious purposes in the region. This most sought after species is a critically endangered species with its distribution in South Africa restricted to Thengwe village in Vhembe District municipality. It is therefore crucial to develop various propagation protocols in order to increase the availability of this species and expand its distribution area in the region. Despite the Tiawoun et al.; ARRB, 29(5): 1-13, 2018; Article no.ARRB.44847 2 risk of extinction and the multipurpose uses, there is a lack of scientific knowledge about many aspects of this plant species. This study revealed that mostly bark is being collected for medicinal use. The aim of the current study was to compile up-to-date scientific information about this critically endangered plant species to promote its conservation. In view of the importance of conservation of such a red-listed plant species, the present review focused on various aspects necessary in strengthening its conservation strategies. Review Article
