Resumen:
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 %), linalool (>10 %),
limonene (>7 %) and alpha-terpineol (>5 %). The essential oil (MIC,
19-30 mu g mL(-1)), phenylacetonitrile (MIC, 45 mu g mL(-1)) and
alpha-terpineol (MIC, 73 mu 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 mu g mL(-1)), phenylacetonitrile and
alpha-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 (beta-cryptoxanthin and
beta-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.
