“…Estragole was previously detected in the essential oil of betel leaf as the major compound (Madhumita et al, 2019), which was detected in our study in low concentration. Francis et al (2021) reported that hexadecanoic acid, hexadecanoic acid methyl ester and phytol were major compounds identified in the leaf extract of J. curcas with antifungal activity.…”

T HE GENUS Jatropha holds great promise as a potential novel drug source because it have many useful activities and phytochemical constituents. This study evaluated the phytochemical composition, anticancer effects against HepG2 (Hepatocellular carcinoma cell line), and antimicrobial efficiency of methanol leaf extracts from Jatropha curcas L., Jatropha gossypifolia L., and Jatropha multifidia L. in vitro. Flavonoids, tannins, alkaloids, saponins, terpenes and sterols were detected in the methanol extracts of both J. curcas and J. gossypifolia. The leaf extract from J. curcas exhibited high effectiveness against the HepG2 cell line, with a selective index of 2.04, as well as effective against Gram-positive and Gram-negative bacteria. Two fractions (JCF1 and JCF2) were collected after the crude methanol extract was purified from J. curcas using a silica gel column. Gram (+ve) bacteria were the only ones susceptible to JCF1, but Gram (+ve) and Gram (-ve) bacteria were both susceptible to JCF2. Hexadecanoic acid (18.43%), anethole (18.28%), estragol (18.28%), oleic acid (13.67%), phytol (10.84%), and carvacrol (7.56%) were found to be the most abundant components of JCF1 in a Gas Chromatography-Mass Spectrum (GC-MS) analysis. In contrast, the most abundant chemical components of JCF2 were hexadecanoic acid (18.05 %), hexadecanoic acid methyl ester (9.50 %), octadecanoic acid methyl ester (3.29 %), anethole (3.1 %), estragole (3.1 %), thymol (1.61%), and carvacrol (1.61%).

“…E-15-heptadecenal and E-14-hexadecenal are reported to be involved in antifungal activity. E-15-heptaedecenal is found in the B. siamensis active compound profle which is allegedly involved in antimicrobial Antimicrobe [47][48][49]; antitumor [50] activity of B. siamensis C.38 against some phytopathogenic fungi [32], while E-14-hexadecenal is the antifungal bioactive compound found in the endophytic fungi Pseudarthria viscida (L.) [25,55]. 1-Heneicosanol is the longchain fatty alcohol which is reported to have antimicrobial activity against some pathogenic bacteria.…”

Exploration studies of endophytic bacteria from Arcangelisia flava (L.) and their potential have not much been conducted. This research aims to explore and characterize the antimicrobial activity of endophytic bacteria in A. flava against pathogenic bacteria. This research consists of several steps including the isolation of bacteria, screening of the antimicrobial activity assay using the dual cross streak method, molecular identification through 16s rDNA analysis, and characterization of bioactive compound production through PKS-NRPS gene detection and GC-MS analysis. There are 29 endophytic bacteria that were successfully isolated from A. flava. The antimicrobial activity showed that there are four potential isolates AKEBG21, AKEBG23, AKEBG25, and AKEBG28 that can inhibit the growth of pathogenic bacteria such as Escherichia coli, Staphylococcus aureus, and Pseudomonas aeruginosa. The 16S rDNA sequence analysis showed that these isolates are identified as Bacillus cereus. These four isolates are identified as able to produce the bioactive compounds through the detection of polyketide synthase (PKS) and nonribosomal peptide synthase (NRPS)-encoding genes. B. cereus AKEBG23 has the highest inhibition against pathogenic bacteria, and according to the GC-MS analysis, five major compounds are allegedly involved in its antimicrobial activity such as butylated hydroxytoluene (BHT), diisooctyl phthalate, E-15-heptadecenal, 1-heneicosanol, and E-14-hexadecenal. This result suggested that B. cereus AKEBG23 as the endophytic bacterium from A. flava has a beneficial role as well as the plant itself. The bacterium produces several bioactive compounds that are allegedly involved in its antimicrobial activity against pathogenic bacteria.

Biodiesel Industrial Waste based onJatropha curcasas a Fungicide to ControlFusarium oxysporumandAlternaria solani

Fusarium oxysporum (Schlecht. emend. Snyder & Hansen.) is the most devastating pathogens causing wilt disease on the tomatoes (Solanum lycopersicum L.) plant, whereas Alternaria solani (Sorauer), is a pathogen that caused early blight on potatoes (Solanum tuberosum L.) Jatropha curcas L. is a biodiesel material known as a potential fungicide. The industrial biodiesel waste based on J. curcas was not yet observed, particularly on the utilization of waste mainly for green manure and biogas. This research aimed to evaluate the extract of industrial biodiesel waste based on J. curcas against F. oxysporum and A. solani. There were 2 × 103 mg L-1 , 4 × 103 mg L-1 , 6 × 103 mg L-1 , 8 × 103 mg L-1 , and 10 × 103 mg L-1 of crude extract that were tested on both pathogens in vitro and in vivo. The concentration of the extract was in an effective range of 10 × 103 mg L-1 and was able to inhibit the growth of all isolates of F. oxysporum from both locations by more than 80 %, but the inhibition of the pathogen A. solani was less than 76 %.
