This study aimed to determine the antifungal activity of leaf aqueous and hydroethanolic extracts of 10 plants from the Brazilian Cerrado on Colletotrichum gloeosporioides and Corynespora cassiicola. Antifungal activity was measured through the incorporation of each extract in a culture media or spore suspension, at 50% concentration relative to the volume, determining respectively the mycelial growth and the spore germination. Then, the percentages of mycelial growth inhibition and spore germination inhibition were obtained based on the comparison with the control. The extracts had a variable action on the phytopathogens, from mycelial growth stimulation for Aristolochia esperanzae and Byrsonima verbascifolia extracts to complete inhibition of mycelial growth and spore germination for Myracrodruon urundeuva and Lafoensia pacari extracts. M. urundeuva, L. pacari and Caryocar brasiliense leaf extracts had antifungal activity against Colletotrichum gloeosporioides and Corynespora cassiicola; the hydroethanolic extracts presented more antifungal activity than the aqueous extracts, and spore germination of both phytopathogens was more affected than their mycelial growth.Key words: aqueous extract, hydroethanolic extract, spore germination, mycelial growth, alternative control RESUMO: Atividade antifúngica de extratos de plantas do Cerrado brasileiro sobre Colletotrichum gloeosporioides e Corynespora cassiicola. O objetivo deste trabalho foi determinar a atividade antifúngica de extratos aquosos e extratos hidroetanólicos de folhas de 10 plantas do Cerrado brasileiro sobre Colletotrichum gloeosporioides e Corynespora cassiicola. A determinação da atividade antifúngica foi realizada pela incorporação do extrato em meio de cultura ou na suspensão de esporos, na concentração de 50% em relação ao volume, determinandose, respectivamente, o crescimento micelial e a germinação de esporos. Em seguida, pela comparação com a testemunha, foram obtidas as percentagens de inibição do crescimento micelial e da germinação dos esporos. Foi constatado comportamento variável dos extratos sobre os fitopatógenos, desde o estímulo no crescimento micelial para os extratos de Aristolochia esperanzae e Byrsonima verbascifolia, até a inibição completa do crescimento micelial e dagerminação dos esporos para os extratos de Myracrodruon urundeuva e Lafoensia pacari.

“…Termiticidal and repellence bioassays revealed that the extract showed no termiticidal activity, though it induced repellent effect against N. corniger (Sá et al, 2009a). Insects closed the galleries constructed in agar next to peripheral wells containing the extract ( Figure 3B).…”

“…The studies on M. urundeuva heartwood indicate that two mechanisms seem to be involved in the resistance of this tissue against N. corniger: prevention of the arrival and attack of N. corniger by repellent action of secondary metabolites, and death of termites induced by MuHL, the heartwood lectin (Sá et al, 2009a).…”

Objective: This study aimed to obtain standardised dry extracts of Miracrodruon urundeuva Allemão using spray-dryer and evaluate the stability of the extracts. Methods:It evaluated the drying parameters: Proportion of colloidal silicon dioxide (CSD) (10, 15 and 20%), inlet temperature (160, 170 and 180 °C) and feed rate (4, 6 and 8 ml/min). The study of the accelerated stability of dry extract occurred in temperature of 40 °C (±2 °C) and relative humidity of 75% (±5%) for 6 mo. The anti-inflammatory activity of the dry extract was evaluated in Swiss mice by the paw edema method. Results:Variations in drying conditions did not represent significant variations in yields of the process. The drying temperature and feed rate significantly influenced the concentration of quercetin (p≤0.05). The increase in inlet temperature and feed flow promoted the increase of quercetin concentration in the extracts. The stability study showed that the concentration of quercetin in dry extract was stable over a period of 6 mo. The dry extract showed anti-inflammatory activity in mice orally. Conclusion:A condition of 10% of colloidal silicon dioxide with an 180 °C inlet temperature and a feed rate of 8 ml/min was considered the most adequate for obtaining the extracts and the drying process resulted in stable dry extracts and the quercetin was a suitable biomarker for monitoring the process.
