TI - Essential oil of Lepidium virginicum: Protective activity on anthracnose disease and preservation effect on the nutraceutical content of tamarillo fruit (Solanum betaceum) KW - LEPIDIUM VIRGUNICUM KW - ESSENTIAL OIL KW - COLLETOTRICHUM ACUTATUM KW - BIOCIDE KW - TAMARILLO N2 - The essential oil from the annual plant Lepidium virginicum L. was chemically characterized in three consecutive years (2018-2020). The essential oils were evaluated in vitro and in situ on the causal agent of anthracnose in tamarillo fruits (Solanum betaceum). The main volatile constituents were phenylacetonitrile (>60 percent), linalool (>10 percent), limonene (>7 percent)and ?-terpineol (>5 percent). The essential oil (MIC, 19-30 ?g mL-1 ), phenylacetonitrile (MIC, 45 ?g mL-1 ) and ?-terpineol (MIC, 73 ?g mL-1 ) caused a significant inhibition in the conidial viability from a wild strain of Colletotrichum acutatum, which was isolated and identified as a causal agent of anthracnose. The inoculation of conidia from C. acutatum in non-symptomatic tamarillo fruits, followed by the in situ treatment with different concentrations of the essential oil (>30 ?g mL-1 ), phenylacetonitrile and ?-terpineol, significantly (p<0.01)avoided the degradation of anthocyanins (delphinidin 3-O-rutinoside, cyanidin 3-O-rutinoside and pelargonidin 3-O-rutinoside)and carotenoids (?-cryptoxanthin and ?-carotene)as well as retarded yellowing and necrosis triggered by anthracnose at least for 10 days. Our results suggest the potential use of the essential oil from L. virginicum as a natural component to preserve the nutraceutical content of tamarillo fruits against C. acutatum infection UR - https://drive.google.com/file/d/1xOopAjjJZCf_cH3WwebpO0DbwsIsCACa/view?usp=drivesdk ER -
