Distribution patterns of flavonoids from three Momordica species by ultra-high performance liquid chromatography quadrupole time of flight mass spectrometry: a metabolomic profiling approach

Bioactive properties and phenolic profile of Momordica charantia L. medicinal plant growing wild in Trinidad and Tobago

“…Compounds 3, 5, 6, 10, 11, 12 were recently identified in M. charantia leaves and additionally, compound 13 was observed in Momordica foetida Schumach. leaves (Madala et al, 2016). From the flavonoids identified in this study, rutin (compound 6) was previously observed in M. charantia fresh leaves (Zhang et al, 2009) and fruits (Kenny et al, 2013).…”

“…Flavonoids were the most represented group of phenolic compounds, being quercetin-O-pentosylhexoside (compound 5) the most abundant molecule. To our best knowledge, this is the first quantitative report of flavonoid glycosides (except for rutin) in aerial parts of wild Momordica charantia as the available studies on these compounds (Madala et al, 2016(Madala et al, , 2014 described qualitative, but not quantitative, occurrence in cultivated M. charantia. More specifically, compounds 4, 7, 8, 9, 13 and 14 were determined for the first time in Momordica charantia species.…”

Pharmacognostic Evaluation of Bitter Melon from Brazilian Northeast (Momordica charantia L.): Identification of Momordicin II

“…It is a flowering vine and contains an array of novel and bioactive phytochemicals. 23,24 The main differential parameter between the varieties is that in the macrocarpa variety the trichomes are less frequent and are of the short multicellular type with 3 to 5 cells, while those of the microcarpa variety are of the long multicellular type with 7 to 11 cells and are rarely starry. From the organoleptic characteristics of the analyzed leaves and stems, the bitter taste, the dark green color and the odor were similar in both varieties of M. charantia L.…”

“…it is observed a hydrogen bonded to a formyl group (δ 10,63) bonded to quaternary carbon, (Figure 3). The NMR 13 C spectrum showed signals for six quaternary carbons (δ 43, 21,147,14,52,03,47,35,49,72,133,66), ten methyl carbons (δ 77,07, 125,75, 67, 17,52,10,38,29,52,71,34,12,77,07,130,58), where among them is the aldehyde carbon in δ 209,27; seven methylene carbons (δ 23,20,29,26,24,14,31,07,36,38,31,38,31,34,45,2). It was observed the presence of carbons related to the β-Glucopyranosyl group (δ 105,62, 76,65, 80,37, 73,31, 79,70), (Figure 4).…”

Flavonoids in Agriculture

“…Another study related with metabolomic profiling is the analysis of flavonoid distribution in three Momordica species, where 13 flavonoids were found in a special pattern [44].…”
