Bottle gourd, Lagenaria siceraria Stand. (Cucurbitaceae), fruit is used in folk medicines and for culinary purposes in Asia. The phenolics of bottle gourd fruit were investigated qualitatively by LC-MS(n). Twenty-two phenolic glycosides were detected and characterized on the basis of their unique fragmentation pattern in the negative ion mode tandem MS spectra. Twenty of them were extracted for the first time from this source, and twelve of them have not been reported previously in nature. It was also possible to distinguish between the individual classes of isobaric phenolic glycosides by tandem and high-resolution mass spectrometry. In this study we also discuss the mass spectrometric fragmentation mechanism of 6-(hydroxycinnamoyl)glucoses. This is the first report of the full characterization of phenolic glycosides of bottle gourd fruit by LC-MS²⁻⁴.

Pigmented rice (Oryza sativa L.) is recognized as a source of natural antioxidant compounds, such as flavonoids, oryzanol, tocopherol, and anthocyanin. Because of their nutritional benefits, anthocyanin-enriched or pigmented rice varieties are feasible alternatives for promoting human health.

Background: The metal oxide nanoparticles possess unique properties such as biological compatibility, superior reactivity, and capacity to develop reactive oxygen species, due to this they have drawn significant interest in cancer treatment. The various MONPs such as cerium oxide, Copper oxide, Iron oxide, Titanium dioxide, and Zinc oxide have been investigated for several types of cancers including brain, breast, cervical, colon, leukemia, liver, lung, melanoma, ovarian, and prostate cancers. However, traditional physiochemical synthetic methods for MONPs commonly include toxic materials, a major concern that raises questions regarding their biocompatibility and safety.

A new megastigmane glycoside, conspurcoside A (), two new phenol glycosides, conspurcosides B () and C (), along with twelve known compounds (-) were isolated from the bark of Croizat. The structures of these compounds were identified through analysis of spectroscopic data, including 1D and 2D NMR, HRESIMS, and ECD methods. Compounds (-, -) were tested for inhibition of NO production in lipopolysaccharide (LPS)-induced RAW 264.

Echium amoenum (borage) powder (EAP) is consumed traditionally and is known to possess health-promoting effects. In this research, application of Echium amoenum (borage) powder (EAP) at levels of zero, 1 and 2 % w/w was investigated in the production of biscuit as a widely consumed snack and some characteristics of dough and biscuit samples were evaluated. By adding EAP and increasing its level, water absorption values and dough stability increased (p < 0.

The winemaking process generates huge amounts of waste every year. Fermented grape pomace, the major by-waste product, holds significant value due to its chemical composition and technological properties. In this study a multi-omics approach was employed for the detailed molecular characterization of fermented grape pomace from Montepulciano grape, a widely used Italian red grape variety.
