A total of 160 street food samples were examined for microbiological quality and food color additives. All food samples were not used unpermitted food color additive, and the rate of microbiological contamination was 20.6%. No S.aureus were found at the lowest dilution used for all samples of cooked meat. Foods served hot had low bacterial contamination.

A total of 200 housewives at home and street vendors were interviewed by using structured questionnaires, the result has indicated the insufficient knowledge of food safety, most of them never had lessons in food handling practices. The environmental sanitary condition and food handling practices at home were better than at the street side. Stagnant wastes were found around 59% of the selling places of street vendors. 71% street foods prepared 2 hours before. Contacted foods with bare hands usually during street food preparation (89%). The practices and knowledge of food safety should be encouraged. A training guide gives clear information on how food becomes contaminated and on the measures that should be taken to avoid such contamination is essential.

Soluble epoxide hydrolases (sEH) are enzymes present in all living organisms, metabolize epoxy fatty acids to 1,2-diols. sEH in the metabolism of polyunsaturated fatty acids plays a key role in inflammation. In addition, the endogenous lipid mediators in cardiovascular disease are also broken down to diols by the action of sEH that enhanced cardiovascular protection. In this study, sEH inhibitory guided fractionation led to the isolation of five phenolic compounds trans-resveratrol (1), trans-piceatannol (2), sulfuretin (3), (+)-balanophonin (4), and cassigarol E (5) from the ethanol extract of the seeds of Passiflora edulis Sims cultivated in Vietnam. The chemical structures of isolated compounds were determined by the interpretation of NMR spectral data, mass spectra, and comparison with data from the literature. The soluble epoxide hydrolase (sEH) inhibitory activity of isolated compounds was evaluated. Among them, trans-piceatannol (2) showed the most potent inhibitory activity on sEH with an IC₅₀ value of 3.4 µM. This study marks the first time that sulfuretin (3) was isolated from Passiflora edulis as well as (+)-balanophonin (4), and cassigarol E (5) were isolated from Passiflora genus.
