“…The tannins and flavonoids found in A. humile may be responsible for this antifungal effect. The capacity of plant secondary metabolites to inhibit the growth of microorganisms has been mainly attributed to tannins and flavonoids (Havsteen, 2002; Ferreira et al, 2012). The antifungal activity of flavonoids is already well known, especially of some dermatophytes (Das & Rosazza, 2006).…”

“…Tannins and flavonoids are effective in the treatment of digestive tract diseases (Zayachkivska et al, 2005; Correia et al, 2006) and are used in the production of topical drugs (Havsteen, 2002; Das & Rosazza, 2006). These compounds were detected in leaves of A. humile (Ferreira et al, 2012) and in the bark of A. occidentale (Chaves et al, 2010), and their presence was related to antiulcerogenic and antibacterial activities in A. humile (Ferreira et al, 2012).…”

Leaves of Anacardium humile are used in Brazilian traditional medicine for the treatment of intestinal disturbances and skin lesions. This study aimed to define leaf diagnostic structural characters, to propose a new method of phytochemical analysis of secretions, prospect flavonoids and alkaloids, and to evaluate their inhibitory activity on Candida albicans. Common anatomical, phytochemical, and microbiological methods were used. Leaves of Anacardium occidentale were used as a reference for the structural analyses. The main structural characters were closed vascular system, absence of ducts at the medulla, bilateral mesophyll, absence of bundle sheath extension, and secretory idioblasts at the xylem. The ducts present schizogenous origin, and secreting activity is restricted to the initial phases of leaf blade expansion. The proposed new phytochemical method is practical and inexpensive and has potential for wide application. The abundance of tannins and flavonoids is related to medicinal use. A single peak in high-performance liquid chromatography indicated the presence of a pure substance not previously reported. The extract had a strong inhibitory effect on C. albicans. The obtained results confirm the potential of A. humile for the prospection of new bioactive compounds.

“…Leaf extracts of A. humile rich in tannins presented antibacterial activity against S. aureus, P. aeruginosa and E. faecalis [116]. The species A. microcarpum exhibited antioxidant activity in the DPPH (IC 50 ) assay from the ethyl acetate fraction (27.9) and ethanol fraction (32.9) of the stem bark and, also for lipid peroxidation induced by Fe 2+ in rat brains and liver homogenates [117].…”

Anacardium plants are native to the American tropical regions, and Anacardium occidentale L. (cashew tree) is the most recognized species of the genus. These species contain rich secondary metabolites in their leaf and shoot powder, fruits and other parts that have shown diverse applications. This review describes the habitat and cultivation of Anacardium species, phytochemical and nutritional composition, and their industrial food applications. Besides, we also discuss the secondary metabolites present in Anacardium plants which display great antioxidant and antimicrobial effects. These make the use of Anacardium species in the food industry an interesting approach to the development of green foods.

“…Plants rich in tannins are employed in traditional medicine to treat a number of diseases (Haslam, 1996;De Bruyne et al, 1999). Extensive analyses have revealed diverse biological activities of this class of substances (Matsuo et al, 1994;Haslam, 1996;Lee et al, 2000), including their ability to inhibit the growth of microorganisms (Scalbert, 1991;Akiyama et al, 2001;Ferreira et al, 2012).…”

The aim of this study was to quantify and evaluate the antibacterial activity of tannins extracted from leaves of Psidium guineense, obtained using two different isolation methods, against Staphylococcus aureus and Pseudomonas aeruginosa. The first extraction method was used to isolate condensed tannins (Method A) and the second to isolate mixtures rich in esters of gallic acid and glucose (Method B). Both extraction methods yielded high concentrations of tannins, with 312 and 257 mg/g of dry material obtained using Methods A and B, respectively. These compounds formed halos of growth inhibition in S. aureus and P. aeruginosa cultures. Tannins isolated by method B gave rise to larger inhibition halos than those isolated by method A. Analysis of the antibacterial activity of tannins isolated by method B revealed a minimum inhibitory and bactericidal concentration of 256 μg/ml for S. aureus and 512 μg/ml for P. aeruginosa. These results demonstrate that P. guineense is a promising source of pharmacologically active tannin molecules, and further studies are therefore necessary to determine the toxicity of the plant and ensure its safe use for animal and human health.
