Original articles Distribution patterns of flavonoids from three Momordica species by ultra-high performance liquid chromatography quadrupole time of flight mass spectrometry: a metabolomic profiling approach. Introduction Momordica species are versatile plants belonging to the family Cucurbitaceae and are often referred to by various common names such as bitter gourd, bitter cucumber and bitter melon Nagarani et al.
Materials and methods Plant materials and chemicals Momordica plants, Curcubitaceae, were collected in and around the Venda region of South Africa with the help of the local farmers. Multivariate data analyses Primary raw data was analyzed by data alignment, peak finding, peak integration and retention time Rt correction using a Markerlynx XS TM software Waters Corporation, Milford, USA with the following processing parameters: Rt range of 7—12 min, mass range of — Da, mass tolerance of 0.
Identification of kaempferol flavonoids Similarly, kaempferol-bearing flavonoids were also identified using the approach as described for quercetin flavonoids.
Identification of isorhamnetin flavonoids In comparison to the former two types of flavonoids, the isorhamnetin class was found to be the least abundant in the three Momordica species investigated. Conclusion While some reports on the flavonoids from M. Appendix A Supplementary data Supplementary material related to this article can be found, in the online version, at doi References Ablajan, K. Received: January 15, ; Accepted: March 14, Flavonoids are found in tea, red wine, and a variety of vegetables and fruits.
Any of various compounds that are a subset of this group, including the flavones, flavanols, and flavonols, as distinguished from the isoflavonoids.
Also called In both senses also called bioflavonoid. Any of a large group of water-soluble plant pigments that are beneficial to health.
Flavonoids are polyphenols and have antioxidant, anti-inflammatory, and antiviral properties. They also help to maintain the health of small blood vessels and connective tissue, and some are under study as possible treatments of cancer.see

There was a significant positive relationship between monthly rainfall, monthly minimum temperatures and flavonoid concentration, but no relationship was found with leaf age.
From Cambridge English Corpus. In seeds, flavonoids are concentrated in the seed coat, which serves to protect the embryo and nutrient reserves until germination is induced. These examples are from the Cambridge English Corpus and from sources on the web.
