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.

Purple passion fruit (Passiflora edulis Sims) is one of the introduced tropical plants, an increasing interest has arisen due to its distinctive taste and attractive flavor. It is expected that passion fruit production and planted area will increase gradually in the years ahead because of high profitability and consumer's demands of healthful ingredients. So we tried to investigate the effect of plant growth regulators and antioxidants on in vitro plant regeneration and callus induction from leaf explants of passion fruit for an establishment of optimal mass propagation system. Young leaf explants of purple passion fruit were cultured in Murashige and Skoog (MS) medium containing different growth regulators and antioxidant additives to induce the shoot organogenesis. After 8 weeks, the highest embryogenic callus formation rate was obtained in MS medium supplemented with $1mg{\cdot}L^{-1}$ 6-benzylaminopurine (BAP) and $2mg{\cdot}L^{-1}$ 2,4-dichlorophenoxyacetic acid (2,4-D), furthermore, the shoot development via organogenesis was also observed. Silver nitrate ($AgNO_3$), which was added into the medium to minimize the adverse effects of leached phenolics, was effective for reduction of medium browning and sudden explant death. In the medium supplemented with $1mg{\cdot}L^{-1}$ BAP and $1mg{\cdot}L^{-1}$ gibberellic acid ($GA_3$), shoots were most vigorously regenerated and elongated. Most shoots rooted successfully in half strength medium with $1mg{\cdot}L^{-1}$ indol-3 acetic acid (IAA), and more than 90% of plantlets survived after 4-month acclimatization period.

In July 2020, total RNA was extracted from passion fruit (Passiflora edulis) leaves showing virus symptoms such as chlorotic spots and vein banding in Haenam, South Korea. Cucumber mosaic virus (CMV)-HN2 was identified through reverse transcription polymerase chain reaction and sequencing analysis. To confirm the biological characteristics of the CMV infecting passion fruit, 10 indicator plants were inoculated with CMV-HN2, and the results showed a typical CMV symptoms. Phylogenetic analysis based on the amino acid of the coat protein (CP) of CMVs revealed that the CMV passion fruit isolates belonged to subgroup I, among which CMV-HN2 belonged to subgroup IA. Additionally, CMVs isolated from passion fruit in Korea have amino acid sequence variation between the subgroup. Among them, CMV-HN2 had four to eight amino acid differences in CP from other CMV isolates from passion fruit. These results confirm the presence of genetic diversity in the CPs of passion fruit CMV isolates.

Passion fruit fiber pectin gels represent a new alternative pectin source with potential for food and non-food applications on a commercial scale. Pectic polysaccharides were extracted from passion fruit (Passiflora edulis) fiber using citric acid as a clean catalyst and autoclaved for 20 to 60 min at $121^{\circ}C$. The best condition of pectin yield with the highest molecular weight was obtained with 1.0% of citric acid (250 mg/g dry passion fruit fiber pectin) for 20 min of autoclaving. Spectroscopic analyses by Fourier transform infrared, enzymatic degradation reactions, and ion-exchange chromatography assays showed that passion fruit pectin extracted for 20 min was homogeneous high methoxylated pectin (70%). Gel permeation analysis confirmed that the pectin extract obtained by autoclaving by 20 min showed higher molecular weights than those autoclaved for 40 and 60 min. Passion fruit pectin extracted for 20 min was enzymatically modified with fungal pectinmethylesterase to create restructured gels. Short autoclave treatment (20 min) with citric acid as extractant resulted in a significant increase of gel strength, improving pectin extraction in terms of functionality. The treatment of solubilized material (pectic polysaccharides) in the presence of insoluble material (cellulose and hemicellulose) with pectinmethylesterase and calcium led to the creation of a stiffer passion fruit fiber pectin gel, while syneresis was not observed.

This research aimed to evaluate the effectiveness of hot water ($43-53^{\circ}C{\cdot}5min^{-1}$; $47^{\circ}C{\cdot}2-6min^{-1}$), 1-methylcyclopropene (1-MCP) at $50-300nL\;L^{-1}$ and a combination of hot water ($47/49^{\circ}C{\cdot}5min^{-1}$) and phosphite $40%\;P_2O_5+20%\;K_2O$;$40%\;P_2O_5+10%\;Zn$) in anthracnose control and the effect on fruit quality [fresh weight loss (FWL-%); pH, total soluble solids ($TSS-^{\circ}Brix$), and titratable acidity (TA = % citric acid (CA)] of passion fruit ( Passiflora edulis f. flavicarpa ) at the postharvest stage. When the fruits were in the stage of 0% dehydration and fully yellow peels, they were disinfested and inoculated with Colletotrichum gloeosporioides. They were then subjected to the above mentioned treatments; this was followed by incubation for 120 h. The diameter of the disease lesions was monitored daily. After the incubation, a physico-chemical analysis was performed. Hot-water treatment resulted in disease reduction at 47 and $49^{\circ}C$ for 4 and 5 min. The combination of hot-water treatment at $47^{\circ}C$ (4 or 5 min) and application of the phosphite of K or Zn significantly reduced disease severity in fruits. The 1-MCP treatment reduced anthracnose severity in passion fruit mainly at $200nL\;L^{-1}{\cdot} 24h^{-1} $. None of the treatments significantly changed the physico-chemical characteristics of the fruit [FWL (2.6-4.1%); pH (3.2-3.5), TSS ($8.9-10.9^{\circ}Brix$), and TA (1.8-2.5% CA)].
