Volatile constituents of Malay rose apple [Syzygium malaccense (L.) Merr. & Perry]

Abstract

The volatile constituents of Malay rose apple fruits [Syzygium malaccense (L.) Merr. & Perry] growing in Cuba were analysed by GC-MS and GC; 133 compounds were identified in the aroma concentrate, of which 2-phenylethanol and its esters (2-phenylethyl acetate, 2-phenylethyl isopentanoate, 2-phenylethyl benzoate and 2-phenylethyl phenylacetate) were found to be the major constituents. By correlating odour thresholds with the concentrations of volatiles (odour unit values), the relative contribution of individual compounds in fruit aroma was assessed. The exotic aroma character of Malay rose apple is the interaction of rose (2-phenylethanol and its esters) and herbaceous (1-octen-3-ol) notes contributing to the complexity of the aroma.

Tritirachium oryzae and Other Endophytic Mediated Jambu Bol (Syzygium malaccense) are Potential as an Antioxidant

“…The group of antioxidant compounds present in the host, especially in S. malaccense fruit contains more complex compounds such as anthocyanins such as cyanidin 3-glucoside, followed by cyaniding 3,5-glucoside and peonidin 3-glucoside (Batista et al, 2017;Nunes et al, 2016), because anthocyanins are phenol derivatives other than avonoids (Zeb, 2020) . In the essential oil of guava fruit S. malaccense 2-phenyl ethanol and its esters (2-phenylethyl acetate, 2-phenylethyl isopentanoate, 2-phenylethyl benzoate and 2-phenylethyl phenylacetate) and herbs (1-octen-3-ol) contributes to the complexity of the aroma (Pino et al, 2004) . Similar compounds, such as 2-(4-Hydroxyphenyl)-5-(3-hydroxypropenyl)-7-methoxybenzofuran, which is a derivative of ailanthoidol, have been reported to have been isolated from a neolignan from Zanthoxylum ailanthoides and Salvia miltiorrhiza Bunge.…”

Complete chloroplast genome sequence and phylogenetic analysis of Syzygium malaccense

“…The fruits of Syzygium malaccense are pyriform with external colors of yellow, pink, or purple, and the soft flesh of the ripe fruit has a pleasant sweet flavor with a characteristic rose aroma (Pino et al. 2004 ). The edible rate of Syzygium malaccense ripe fruit is more than 80%, and its fruit have high nutritional value.…”
