Analysis by UPLC–DAD–ESI-MS of Phenolic Compounds and HPLC–DAD-Based Determination of Carotenoids in Noni (Morinda citrifolia L.) Bagasse

Abstract

Noni bagasse is usually wasted after the noni juice extraction process. The purpose of this study was to investigate the phytochemical composition of noni bagasse (with and without seeds) obtained after a 1 week period of a shortterm juice drip-extraction process from over-ripe noni fruit. Totals of free phenolics, flavonoids, condensed tannins, carotenoids, and most of the minerals were higher in bagasse without seeds (NSB) than in bagasse with seeds (WSB), whereas bound phenolics and total and insoluble dietary fiber were higher in WSB than in NSB. β-Carotene and lutein, quantified by HPLC− DAD, were higher in both bagasse than in juice. A total of 16 phenolic compounds and 2 iridoids were determined by UPLC− DAD−ESI-MS. Among them, procyanidin B-type dimer, caffeoylquinic-acid-hexoside, and quercetin-hexose-deoxyhexose have not been previously reported in noni bagasse, noni juice, or noni fruit. Isorhamnetin-3-O-rutinoside was the most abundant compound in both bagasses. In conclusion, both bagasses are potential sources of phytochemical compounds for the food and pharmaceutical industries.

Novel insights into the fruit and seed extracts ofMorinda morindoides(Baker) Milne‐Redh: HPLC‐ESI‐Q‐TOF‐MS profiling, antioxidant, and enzyme inhibitory propensities

“…This compound has been previously reported in M. citrifolia (Barraza‐Elenes et al, 2019) and M. officinalis (Kim et al, 2005). Compound 7 was identified as asperulosidic acid by its exact mass and fragment ions at m/z 269 and 251; it has been previously reported in M. citrifolia (Barraza‐Elenes et al, 2019; Dussossoy et al, 2011). Compound 8 was tentatively described as a saccharide derivative based on bibliographic information (Spínola, Pinto, & Castilho, 2015).…”

“…Compound 1 was identified as a disaccharide (two hexosides) based on its exact mass and fragment ions at m / z 179, 161, 143, and 119. Compound 3 was characterized as the iridoid deacetylasperulosidic acid based on its molecular formula and fragment ions at m/z 227, 209, 183, and 165 (Barraza‐Elenes et al, 2019; Heffels, Müller, Schieber, & Weber, 2017). This compound has been previously reported in M. citrifolia (Barraza‐Elenes et al, 2019) and M. officinalis (Kim et al, 2005).…”

Organic matter and shading on ion accumulation in soil cultivated with noni under salinity

“…Noni (Morinda citrifolia L.) is a perennial plant belonging to the Rubiaceae family, which stands out for its ability to tolerate environmental stresses, such as salinity (Nivas et al, 2011;Barraza-Elenes et al, 2019). This species can be cultivated in the Brazilian Northeast, a region that has problems with the accumulation of salts in the soil and water sources, especially in semi-arid areas (Lucena et al, 2018).…”

Anticancer effects of the combined Thai noni juice ethanolic extracts and 5-fluorouracil against cholangiocarcinoma cells in vitro and in vivo

“…Currently, noni juice has been used as an herbal drink and is commercially available worldwide. Noni fruit juice is a natural source of numerous bioactive compounds, including phenolic acids, flavonoids, iridoids and coumarin 11 . Previous research revealed that the noni juice does not induce adverse effects in hepatocytes, and renal function or show subchronic oral toxicity 12 , 13 .…”
