Volatile Components from Mango (Mangifera indicaL.) Cultivars

Abstract

The volatile components of 20 mango cultivars were investigated by means of simultaneous distillation-extraction, GC, and GC-MS. Three hundred and seventy-two compounds were identified, of which 180 were found for the first time in mango fruit. The total concentration of volatiles was approximately 18-123 mg/kg of fresh fruit. Terpene hydrocarbons were the major volatiles of all cultivars, the dominant terpenes being delta-3-carene (cvs. Haden, Manga amarilla, Macho, Manga blanca, San Diego, Manzano, Smith, Florida, Keitt, and Kent), limonene (cvs. Delicioso, Super Haden, Ordonez, Filipino, and La Paz), both terpenes (cv. Delicia), terpinolene (cvs. Obispo, Corazon, and Huevo de toro), and alpha-phellandrene (cv. Minin). Other qualitative and quantitative differences among the cultivars could be demonstrated.

Identification of a new antinociceptive alkaloid isopropyl N-methylanthranilate from the essential oil of Choisya ternata Kunth

“…Two peaks in the GC chromatograms (detected in both samples 1 and 2) that were tentatively identified (based on mass spectral comparison with the MS from the Wiley-NIST data base) as methyl (2) and isopropyl (1) N-methylanthranilates were of great interest since nitrogen volatiles are known as potent floral volatiles that are difficult to detect and are frequently missed out during the analyses (Jabalpurwala et al, 2009). A literature survey on these two compounds gave the following results: the methyl ester of N-methylanthranilic acid (2) was previously reported from a number of Rutaceae species (belonging to one of the two sister subfamilies, Rutoideae and Aurantioideae, namely the genera Zanthoxylum (Detoni et al, 2009;Dreyer and Brenner, 1980), Citrus (Brophy et al, 2001;Jabalpurwala et al, 2009;Lota et al, 2000;Tomi et al, 2008), Fortunella Pino, 2009a, 2009b;Umano et al, 1994) and Murraya (Imai et al, 1989), respectively) with some sporadic (most frequently singular) occurrence (in low amount) in the unrelated genera Chamaecyparis (Thomas et al, 1966), Corydalis (Olesen and Knudsen, 1994), Jasminum (Calvarano, 1966;Cheng and Chao, 1979;Ito et al, 2002;Kaiser, 1988;Toda et al, 1983), Mangifera (Pino et al, 2005), Michelia (Kaiser, 1991), Siphonochilus A c c e p t e d M a n u s c r i p t 25 (Viljoen et al, 2002), and Trifolium (Honkanen et al, 1969). However, the isopropyl ester (1) has never been detected in a sample of natural origin.…”

Characterization of aroma-active compounds in black sapote (Diospyros digynaJacq.)

“…In comparison with other tropical fruits, this represent a low level, e.g. 1.5 mg kg -1 in star apple (Pino et al, 2002), 12.8 μg kg -1 in papaya (Pino et al, 2003a), 240-332 mg kg -1 in bullock's heart (Pino et al, 2003b), 18-123 mg kg -1 in mango (Pino et al, 2005), 6.5 mg kg -1 in sapote and 18.8 mg kg -1 in yellow sapote (Pino, 2010), determined by using the same isolation technique. The composition of the fruit included 9 terpenes, 11 ketones, 5 aldehydes, 4 alcohols, 2 esters and one paraffin, all of which were reported for the first time.…”

Differentiation of volatile profiles of Thai Oolong tea No. 12 provenances by SPME-GC-MS combined with principal component analysis

“…These compounds have often been reported in previous studies. [3,6,7] the significant differences between the cluster (p < 0.05) Cluster A; tea planted at 400-700 m, Cluster B; tea planted at 700-1,000 m, Cluster C; tea planted above 1,000 m Odor description provided by (1) Wang et al, [6] (2) Sawamura et al, [16] (3) Leffingwell and Alford, [17] (4), Burdock, [18] and (5) Pino et al [19] Although some compounds such as limonene, geranial, linalool acetate, dihydro linalool acetate, 3Z-hexenyl hexanoate, and α-muurolene were detected in relatively high quantities, their formation is independent of altitude. It is notable that some volatile compounds are highly specific to a certain altitude.…”

“…This tea, alongside other hybrids such as No. 17,19, and 21, is planted extensively in Chiang Rai province. Oolong tea No.…”
