Received 14 March, 2017; Accepted 18 April, 2017 Lippia sidoides Cham. (Verbenaceae) is a species native to the Brazilian northeast, widely used in popular medicine. Its leaves were used for the isolation of endophytic fungi and extraction of metabolites. Among them, three were selected according to fungitoxicity tests against the maize phytopathogenic fungus, Curvularia lunata (Wakker). However, the objective of this study was to identify the role of L. sidoides extracts associated with their endophytic fungi, necessary to reduce excess of fungicides applied on the maize crop. Metabolites were evaluated for antioxidant activity by 2.2-diphenyl-1-picrylhydrazyl (DPPH), phenols, total flavonoids and one of it endophytic fungus were evaluated for synergism (Verticilium sp. and plant extracts). The endophytic fungi and plant extracts evaluated for phenolic content ranged from 0.29 ± 0.05 to 96.94 ± 11.86 mgEAG/g, the content of flavonoids from 14.31 ± 1.56 to 192.33 ± 4.58 mgER/g, and antioxidant activity could only be observed for the plant extract with EC50 81 ± 0.3%. The secondary metabolites identified by HPLC in the plant extract were catechin, quercetin, gallic acid and naringin. Naringenin, catechin, epigallocatechin gallate and quercetin were identified in the extract of the fungi viz. Verticillium sp. and Fusarium sp. Synergistic analysis between a 1:1 proportion of plant and fungal extracts has shown more efficient (79.0%) inhibition of C. lunata. Thus, alternative control of phytopathogenic fungi can be accomplished using plant extracts associated with their endophytic fungi, reducing the excess of fungicides applied on the maize crop. Key words: Curvularia lunata, endophytic fungal, HPLC, extract, Verticillium sp., Fusarium sp., Colletrotrichum sp. INTRODUCTION Endophytic fungi isolated from plants belonging to important new sources of bioactive compounds for tropical regions produce more active secondary applications in agriculture, medicine, and the food metabolites than those from temperate regions, because industry (Yadav et al., 2014b; Sadananda et al., 2011). they are exposed to an environment of greater biodiversity Over time, some endophytic fungi have developed the (Bhardwaj et al., 2015). These fungi are recognized as ability to produce the same or similar bioactive Ferreira et al. 297 substances to those produced by host plants (Sharma et 1990s, it has caused economic loss in maize crop al., 2016). This lends a great advantage to the study of productivity in China (Gao et al., 2015) and has been the relationships between endophytes and their host progressing in recent years in Brazil (Assunção et al., plants (Fouda et al., 2015). Nevertheless, most of the 2006). The pathogen mainly infects maize leaves, leaf time, these valuable bioactive compounds are scarce in sheaths, and husks and causes soaked or yellow necrotic nature; therefore, the development of a substitute spots in the early stages, which then expand to round, approach for their efficient production is warranted oval, spindle-shaped, or strip lesions (Hou et al., 2013). (Kusari et al., 2013). The green leaf area of maize is considered the main More recent estimates based on high-throughput source of photoassimilates for the plant (Akram et al., sequencing methods suggest that as many as 5.1 million 2014) and, according to Liu et al. (2016), a loss in this fungal species exist (Taylor et al., 2014). The estimate of source may reflect the development of the plant and the known species has almost tripled in the period between production of grains. 1943 (38000 described species) and the present, In this paper, the objective was the isolation and amounting to an increase of more than 60000 described identification of the endophytic fungus from L. sidoides. species (Blackwell, 2011). Accordingly, endophytes are To this end, antioxidant activity, phenols and total good sources of genetic diversity and new species flavonoids, and the evaluated metabolites were identified belonging to a large group of fungi that colonize tissues by HPLC. The extracts of endophytic fungi and plants of healthy plants without causing apparent symptoms were evaluated by the selective test of fungitoxicity and (Fatima et al., 2016). They protect plants against synergism against C. lunata. herbivores, insect attack, or invading pathogens
