“…In the same way, yields of 2.92% [5], 3.1% [3] have been obtained for L. origanoides. However, these results indicate that these plants in either of the two ecological zones can be proposed as raw material for industrial exploitation since their yields are above the minimum value allowed which is 0.1% [6].…”

The objective of this research is to compare the chemical profiles of the essential oils of Lippia origanoides leaves collected in Santa Marta and Sincelejo at different hours. The leaves were harvested at 6:00 a.m., 12:00 p.m, and 6:00 p.m, the essential oils were extracted by hydrodistillation assisted by microwave radiation and the chemical profiles were determined by gas chromatography coupled to mass spectrometry. The results showed Thymol as the major metabolite in all samples, however, Sincelejo presented the highest percentages of Thymol with 68.02% at 6:00 a.m., while in Santa Marta at 6:00 p.m was 63.19%. In all cases, the lowest concentrations of Thymol were found at 12:00 md, because high temperatures can volatilize this compound and in the case of Santa Marta, because it is a coastal area and temperature at noon is higher than in Sincelejo. Therefore, concentrations of 33.12% and 59.06% were found respectively. A similar case occurs with Ocimeno and 3-Tujeno, which showed a decrease of concentration in this period.

“…Li ppia origanoides (family Verbenaceae) is reported to have remedial properties against different human health disorders (Oliveira et al ., 2014). LOEO is reported to have antifungal and antiaflatoxigenic activity (Cordero et al ., 2018; Brandao et al ., 2021). However, literature on antifungal and anti‐AFB 1 potential of LOEO nanoformulation is unavailable.…”

Summary The study explores in vitro antifungal and aflatoxin B1 inhibitory potency of chemically characterised Lippia origanoides EO (LOEO) encompassed in chitosan nanoparticle (CS‐LOEO‐Np). CS‐LOEO‐Np was physico‐chemically characterised through XRD, SEM and FTIR analyses. CS‐LOEO‐Np exhibited improved antifungal and AFB1 inhibitory efficacy (0.05 and 0.045 µl mL−1, respectively) in contrast to LOEO (0.30 and 0.25 µl mL−1, respectively). Bioactivity of LOEO loaded nanoparticle was enhanced as reflected by depletion in ergosterol content, rapid cellular ion release and reduced methylglyoxal content. IC50 value equivalent to 4.17 µl mL−1 displayed better antioxidant potency of CS‐LOEO‐Np as compared to LOEO (IC50 = 6.20 µl mL−1). CS‐LOEO‐Np preserved sensorial attributes of stored Nigella sativa (model food matrix) samples and have higher lethal toxicity dose, that is LD50 = 8832 mg kg−1. Hence, CS‐LOEO‐Np could serve as novel green candidate to ensure food security with better nutritional and sensorial features.
