AbstractThe methanolic extract of sandalwood (SwME) was prepared by soxhlet apparatus and the antibacterial assay was performed. Further, the metabolite profiling of SwME and lysates of E. coli and E. coli grown in the presence of SwME was generated. SwME showed maximum inhibition against E. coli (MTCC 443) i.e. 82.71%, and minimal against B. subtilis (MTCC 736) i.e. 26.82%. The metabolome profiles of E. coli and SwME were generated using gas chromatography-mass spectrometry (GC-MS) technique. Comparative studies were done to understand to what extent metabolite modifications differ between SwME, E. coli lysate and the E. coli strain grown in presence of extract. Result revealed 23 peaks with major compounds present in E. coli were 9-Octadecenoic Acid (Z)-, Methyl Ester (26.85%), Hexadecanoic Acid, methyl ester (20.5%) and Hexadecanoic acid, trimethylsilyl ester (15.79%). When E. coli was grown in the presence of SwME, GC-MS analysis showed 25 peaks with major compounds such as 9-Octadecenoic Acid, Methyl Ester (21.97%), Hexadecanoic Acid, Methyl Ester (17.03%), and Hexadecanoic Acid, Trimethylsilyl Ester (14.96%). Correlating the metabolic profiles with the changes occurring is essential to progression their comprehension and in the development of new approaches to identify the metabolomics regulation in E. coli in response to SwME.

Abstract Dioscorea sansibarensis bulbils are well known for their toxicity and medicinal applications. In this study, the attraction and mortality of the Phaseolus vulgaris weevil (Bruchus chinensis) caused by Dioscorea sansibarensis bulbil oil was examined in a Completely Randomized Design experiment using a Y-tube olfactometer on a laboratory bench. Statistical analysis at P < 0.05 showed 10 µL had an attraction of 42.67%. In the case of mortality, the results showed that Phaseolus vulgaris seeds treated with 40 µL of the bulbil oil had a harmonic mean of 55.8% mortality of the weevil population, which was higher than with 10 µL of Actellic 50 EC. GC-MS analysis identified 17 compounds in the bulbil oil, the main constituents of which were 2- pentanone, 4-hydroxy-4-methyl- (17.8%), phenol, 4-ethyl- (11.41%), hexadecanoic acid, methyl ester (11.05%), phenol (7.35%), 9-octadecenoic acid, (E)- (7.2%) and phenol, 4-ethyl-2-methoxy- (7.14%). Attraction by bulbil oil may have been due to the presence of phenolic compounds, and mortality may have been due to hexadecanoic acid, methyl ester and 9-octadecenoic acid, (E)-. Attractants are used for the surveillance and detection of an infestation in stored products. The added advantage of the bulbil oil to cause mortality makes Dioscorea sansibarensis bulbil oil useful in the formulation of a botanical pesticide in stored pest management.
