“…These differences could be attributed in part to the great complexity of the double membrane-containing cell envelope in Gram-negative bacteria compared to the single membrane structure of the positive ones [ 53 , 54 ]. These differences may be attributed also to the presence of the lipopolysaccharides in the outer membrane of the Gram-negative bacteria, which make them inherently resistant to external agents, such as hydrophilic dyes, antibiotics, detergents, and lipophilic compounds [ 14 , 55 ]. However, the ability of EOs to disrupt the permeability barrier of cell membrane structures and the accompanying loss of chemiosmotic control is the most likely reason for its lethal action [ 56 ].…”

The chemical composition, antioxidant and antimicrobial activities, and the preservative effect of Thymus capitata essential oil against Listeria monocytogenes inoculated in minced beef meat were evaluated. The essential oil extracted was chemically analyzed by gas chromatography-mass spectrometry. Nineteen components were identified, of which carvacrol represented (88.89%) of the oil. The antioxidant activity was assessed in vitro by using both the DPPH and the ABTS assays. The findings showed that the essential oil exhibited high antioxidant activity, which was comparable to the reference standards (BHT and ascorbic acid) with IC50 values of 44.16 and 0.463 μg/mL determined by the free-radical scavenging DPPH and ABTS assays, respectively. Furthermore, the essential oil was evaluated for its antimicrobial activity using disc agar diffusion and microdilution methods. The results demonstrated that the zone of inhibition varied from moderate to strong (15–80 mm) and the minimum inhibition concentration values ranged from 0.32 to 20 mg/mL. In addition, essential oil evaluated in vivo against Listeria monocytogenes showed clear and strong inhibitory effect. The application of 0.25 or 1% (v/w) essential oil of T. capitata to minced beef significantly reduced the L. monocytogenes population when compared to those of control samples (P-value <0.01).

“…Jatropha leaves contain phenols, terpenoids, flavonoids, saponins (Oskoueian et al, 2011), and alkaloids (Gupta et al, 2011). In Sisunandar's research, he said that there was antibacterial activity in the Chinese castor leaf extract (Sisunandar, 2002).…”

This study aims to determine the effect of Jatropha Curcas L. leaf extract on the freshness quality of Layang Fish (Decapterus sp.) At room temperature storage. The research consisted of two stages, namely preliminary research and main research. Preliminary research is determining the concentration of castor leaves. The main research is the concentration of Jatropha leaves used, which is 16% with a storage time of 10 hours, 14 hours, 18 hours and 22 hours. The test was carried out organoleptically (hedonic quality) and TPC. This design uses kruskall wallis for organoleptic data (hedonic quality), CRD to obtain TPC results. Organoleptic data and TPC that had a significant effect were tested by Duncan's continued test. The results showed that the fresh fly fish preserved with 16% castor leaf extract was able to maintain the quality of the fresh fly fish for 14 hours of storage. The chemical test results showed that the fresh fly fish with 16% castor leaf extract in 14 hours of storage, the microbiological quality obtained ALT value of 5.03 CFU / g, this fulfills SNI 2729.2013 concerning fresh fish.

Los metabolitos secundarios presentes en plantas han demostrado ejercer diversas propiedades biológicas, principalmente el grupo de alcaloides, los cuales han sido investigados por su actividad fungicida, capaz de reemplazar a los productos sintéticos. Las especies del género Jatropha han sido estudiadas por su amplia variedad de metabolitos secundarios con potencial antimicrobiano, logrando ser relevantes en la búsqueda de nuevas alternativas al control de hongos de importancia clínica y alimentaria como Aspergillus parasiticus, considerado como una de las principales especies de hongos productores de aflatoxinas. En el presente trabajo se identificó por primera vez por cromatografía en capa fina de alta resolución (HPTLC) la presencia de alcaloides en Jatropha platyphylla y se evaluó la actividad inhibitoria de los extractos metanólicos y fracción enriquecida de alcaloides, a concentraciones de 0.01, 0.1, 0.5, 1 y 2 mg/mL, sobre el crecimiento radial de A. parasiticus. Además se determinó su germinación a partir de la CI50 de los tratamientos. Se observó una mayor actividad de los alcaloides a 2 mg/mL, con el 80 % de inhibición a las 48 h (P< 0,05), con una CI50 de 2.7 mg/mL. Estos resultados evidencian a los alcaloides de J. platyphylla como posibles tratamientos alternativos al control de A. parasiticus.
