“…The antioxidant and radical scavenging activities of the extracts from fruit, seed, peel, leaves, bark of P. edulis have been studied via ABTS (Zas and John, 2017), AAPH, DPPH, FRAP, ORAC, HOCI scavengers and ferrous ions assays in vitro, as well as several in vivo experiments (Rotta et al, 2019). The results showed that aqueous, ethanol, polyphenol-rich in particular extracts of leaf (Thomas et al, 2019), peel and seed from P. edulis demonstrate potential antioxidant and radical scavenging activities. P. edulis fruit showed a higher antioxidant activity (64% of DPPH reduced) than mango, pineapple, banana and…”

Passiflora edulis, also known as passion fruit, is widely distributed in tropical and subtropical areas of the world and becomes popular because of balanced nutrition and health benefits. Currently, more than 110 phytochemical constituents have been found and identified from the different plant parts of P. edulis in which flavonoids and triterpenoids held the biggest share. Various extracts, fruit juice and isolated compounds showed a wide range of health effects and biological activities such as antioxidant, anti-hypertensive, anti-tumor, antidiabetic, hypolipidemic activities, and so forth. Daily consumption of passion fruit at common doses is non-toxic and safe. P. edulis has great potential development and the vast future application for this economically important crop worldwide, and it is in great demand as a fresh product or a formula for food, health care products or medicines. This mini-review aims to provide systematically reorganized information on physiochemical features, nutritional benefits, biological activities, toxicity, and potential applications of leaves, stems, fruits, and peels of P. edulis.

Green Synthesis of Gold and Silver Nanoparticles by Using Amorphophallus paeoniifolius Tuber Extract and Evaluation of Their Antibacterial Activity

In this report, we discussed rapid, facile one-pot green synthesis of gold and silver nanoparticles (AuNPs and AgNPs) by using tuber extract of Amorphophallus paeoniifolius, and evaluated their antibacterial activity. AuNPs and AgNPs were synthesized by mixing their respective precursors (AgNO3 and HAuCl4) with tuber extract of Amorphophallus paeoniifolius as the bio-reducing agent. Characterization of AuNPs and AgNPs were confirmed by applying UV-vis spectroscopy, field-emission scanning electron microscopy (FESEM), X-ray diffraction (XRD) analysis, Fourier transform infrared spectroscopy (FTIR), and energy dispersive X-ray spectroscopy (EDS). From UV-vis characterization, surface plasmon resonance spectra were found at 530 nm for AuNPs and 446 nm for AgNPs. XRD data confirmed that both synthesized nanoparticles were face-centered cubic in crystalline nature, and the average crystallite sizes for the assign peaks were 13.3 nm for AuNPs and 22.48 nm for AgNPs. FTIR data evaluated the characteristic peaks of different phytochemical components of tuber extract, which acted as the reducing agent, and possibly as stabilizing agents. The antibacterial activity of synthesized AuNPs and AgNPs were examined in Muller Hinton agar, against two Gram-positive and four Gram-negative bacteria through the disc diffusion method. AuNPs did not show any inhibitory effect, while AgNPs showed good inhibitory effect against both Gram-positive and Gram-negative bacteria.

“…The peaks around 1200-1000cm -1 are attributed to C-O-bond in alcohol and ethers. 17 The bands between 1310 and 1390cm -1 can be attributed to the C-O-H angular deformations of phenols, characteristic group of flavonoids. 18 The bands between 1576-1560 and 1387/1396cm -1 are identification bands of flavonoids and phenolic acid derivatives.…”

The aim of this work was to extract, characterize and incorporate the extract of Passiflora edulis in to chitosan membranes for potential application as wound dressing. The extract was obtained from leaves using hydroalcoholic maceration. The extract (EPE) was analyzed by LC-Mass and Infrared Spectroscopy for identification of characteristic compounds, and further incorporated to chitosan membrane (QEPE). The membranes were obtained by solvent evaporation technique and characterized by morphology (SEM), swelling behavior, moisture content, water-solubility, water vapor permeability, and thermal stability. The interactions between chitosan and the extract were also analyzed by infrared spectroscopy. The presence of flavonoids (hydrophilic compounds) in EPE affected the moisture content, water-solubility and water-vapor permeability of QEPE by increasing these properties in respect to the values found for the chitosan only membrane (QF). No significant difference was observed in the swelling ratio of both membranes. Moreover, a reduction in the enthalpy of fusion and hence in the degree of crystallinity was observed for QEPE, probably due to the presence of phenolic compounds in the extract that difficult orientation and organization of the polymeric chains due to the steric effect. In conclusion, QEPE was flexible, transparent, and homogeneous; demonstrated fluid absorption capacity, water vapor permeability and thermal stability under physiological conditions. Therefore, it has great potential for application in the treatment of skin wounds.
