Rhodomyrtus tomentosa is a common wood, prevalent in areas with undemanding soil conditions and resistant toward pests and diseases. The plant can be found in China, Taiwan, Philippines, Malaysia, Indonesia, and Vietnam. Literature and artwork indicate that R. tomentosa played an important holistic role in the daily lives of several ancient cultures, providing medicinal benefits. R. tomentosa exhibits a wide spectrum of pharmacological effects and has been used to treat colic diarrhea, wounds, heartburn, abscesses, gynecopathy, and as a pain killer. R. tomentosa was used in traditional Chinese medicine to treat urinary tract infection. 42 compounds have been isolated from this plant and structurally elucidated. They comprise phloroglucinol, flavonoid, terpenoid, anthracene glycoside, tannin, and other compounds. Rhodomyrtone, a member of the acylphloroglucinols demonstrated a significant activity against a wide range of Gram-positive bacteria. Rhodomyrtone exhibited both antimicrobial and anti-infective activities. Several biological activities have been documented as antibacterial, antifungal, antimalarial, osteogenic, antioxidant, and anti-inflammatory. R. tomentosa has been studied extensively for alternative antimicrobial agents. Although rhodomyrtone exhibited potential activity with a very low minimum inhibitory concentration value, the mechanisms of action of this compound are still unclear. Furthermore, toxicity studies on it extract to validate pharmacological activities are required.

“…At a concentration of 200 μg/ml, the ethanolic extract of R. tomentosa leaves exhibited antifungal activity against three pathogenic fungi (Bipolaris setariae, C. oryzae, and R. oryzae-sativa) of rice plants with mycelial inhibition above 50% [40].…”

“…For example, ethanolic extract of Pometia pinnata and dichloromethane extract of Desmos chinensis leaves displayed remarkable activity against Bipolaris setariae and B. oryzae with 94·7 and 70·6% inhibition of mycelial growth, respectively (Plodpai et al . ). Also, the essential oil of O. basilicum completely inhibited the mycelial growth of B. ellisii, B. hawaiensis , B. spicifera, C. australiensis and C. cynodontis at 80 mg ml −1 and fungicidal effect on C. australiensis only at the same concentration.…”

“…Noteworthy, alterations and damage on the morphology of fungal hyphae or conidia treated with plant extracts or essential oils have been described by many researchers (Mares et al 2004;Hashem 2011;Plodpai et al 2013b). The results are in agreement with those obtained by Plodpai et al (2013a) using Desmos chinensis extracts against Rhizoctonia solani and by Soylu et al (2010) using origanum essential oil on Botrytis cinerea.…”

Resumo -O objetivo deste trabalho foi avaliar o efeito de extratos de capeba (Piper marginatum) e nim (Azadirachta indica) sobre o fungo Colletotrichum scovillei e determinar o componente mais ativo no controle pós-colheita da antracnose em pimentão. A atividade de extratos metanólicos das folhas (P. marginatum e A. indica) e das sementes (A. indica) a 0, 125, 250, 500, 1.000 e 2.000 ppm, na inibição do crescimento micelial de C. scovillei in vitro foram avaliadas. O extrato metanólico de folhas de P. marginatum foi o mais ativo e, consequentemente, foi submetido ao fracionamento biomonitorado ("bioassay-guided fractionation"). Esse processo rendeu 10 frações majoritárias, obtidas por cromatografia líquida de alta performance, das quais a fração à concentração de 1,5 ppm inibiu o desenvolvimento de C. scovillei de forma mais eficiente do que o fungicida mancozeb.Termos para indexação: Capsicum annuum, antracnose, controle alternativo, fracionamento biomonitorado, nim. Extracts of Piper marginatum and Azadirachta indica for the control of Colletotrichum scovillei in bell pepperAbstract -The objective of this work was to evaluate the effect of extracts of capeba (Piper marginatum) and neem (Azadirachta indica) on the fungus Colletotrichum scovillei, and evaluate the most active compound on the post-harvest control of anthracnose in bell pepper. Methanolic extracts activity of leaves (P. marginatum and A. indica) and of seeds (A. indica) at 0, 125, 250, 500, 1,000, and 2,000 ppm, for in vitro inhibition of mycelial growth of C. scovillei, were evaluated. The methanolic extract of P. marginatum leaves was the most active and, consequently, it was subjected to a bioassay-guided fractionation. This processing produced ten major compounds, obtained by preparative HPLC, from which the fraction at 1.5 ppm concentration was capable of inhibiting mycelial growth and was more effective than the fungicide mancozeb.
