Sap Phytochemical Compositions of Some Bananas in Thailand

Abstract

Banana sap has some special properties relating to various phenomena such as browning of fruits after harvesting, permanent staining of cloth and fibers, and antioxidant and antibleeding properties. Analysis of banana sap using high-performance liquid chromatography-electrospray ionization-mass spectrometry (HPLC-ESI-MS) indicated the presence of phenolic and aromatic amino compounds of interest due to their special properties. With the online positive electrospray ionization mode (ESI), the possible structures of specific compounds were determined from the fragmentation patterns of each particular ion appearing in the mass spectra. The major compounds revealed from the sap of banana accessions, namely, Musa balbisiana , Musa laterita , Musa ornata , and Musa acuminata , and some cultivars were apigenin glycosides, myricetin glycoside, myricetin-3-O-rutinoside, naringenin glycosides, kaempferol-3-O-rutinoside, quercetin-3-O-rutinoside, dopamine, and N-acetylserotonin. The results indicated that there was a variety of phenolic and aromatic amino contents in many banana species. These compounds were reported to relate with biological activities. Moreover, the identities of these phytochemical compositions may be used as markers for banana diet, the assessment of physiochemical status, or the classification of banana clones.

Spore germination and early gametophyte development of Platycerium wandae (Polypodiaceae) from Papua, Indonesia

“…Experimental studies have suggested that pseuodostem sap possesses haemostatic and antioxidant properties, has both hyper-and hypoglycemic effects, is diuretic, an antidote for snake bite and cures kidney stones (Singh et al 2007;Pothavorn et al 2010;Prasobh and Revikumar 2011;Weremfo et al 2011;Onyenekwe et al 2013;Ponnambalam and Sellappan 2014). The pseudostem sap can also be used in dyeing cloth, for colour and as a mordant (fixative).…”

Nucleotides, micro- and macro-nutrients, limonoids, flavonoids, and hydroxycinnamates composition in the phloem sap of sweet orange

“…56 The presence of flavonoids in root tips of plant grown in light-shield roots suggested that flavonoids are transported from shoot to root. 56 Using fluorescence microscopy, Buer et al (2007) showed that external flavonoids applied to Arabidopsis flavonoid mutants (cannot make flavonoids) accumulates in tissues distal to the application site. 20 In a recent study, many flavonoids were also detected in the phloem sap of banana trees.…”

“…55 Recently, it was suggested that flavonoids are transported within plant. 20,56 Flavonoids are not produced in roots grown in complete darkness because expression of genes encoding enzymes of flavonoids biosynthesis is dependent on light. 56 The presence of flavonoids in root tips of plant grown in light-shield roots suggested that flavonoids are transported from shoot to root.…”

Corrosion inhibition study of bract extract of Musa acuminata inflorescence on mild steel in hydrochloric acid medium

“…No research has been reported on the phytochemical screening of banana flowers except a quantitative study on saponin and flavanoid [7] and later phenolic content by Loganayaki et al [8]. The bract part of Musa paradisiaca was reported to contain anthocyanins such as delphinidin, pelaragonidin, peonidin and malvidin [9,10]. Total phenolic content in bract was reported as the lowest compared to other parts such as rhizome, fruit peel, ovary, petiole, pseudo stem and leaves [11].…”
