Ceiba speciosa (A. St.-Hil.) Seeds Oil: Fatty Acids Profiling by GC-MS and NMR and Bioactivity

Abstract

This study aimed to evaluate the chemical composition by gas chromatography-mass spectrometry (GC-MS) and Nuclear Magnetic Resonance (NMR) analyses, the antioxidant activities evaluated by different in vitro assays namely 2,2-diphenyl-1-picrylhydrazyl (DPPH), 2,2′-azino-bis(3-ethylbenzothiazoline-6-sulphonic acid) (ABTS), Ferric Reducing Ability Power (FRAP), and β-carotene bleaching tests, and the inhibitory effects of enzymes linked to obesity (lipase, α-amylase, and α-glucosidase) of fixed seed oil of Ceiba speciosa (A. St.-Hil.). Fourteen compounds were identified. Linoleic acid (28.22%) was the most abundant followed by palmitic acid (19.56%). Malvalic acid (16.15%), sterculic acid (11.11%), and dihydrosterculic acid (2.74%) were also detected. C. speciosa fixed oil exerted a promising ABTS radicals scavenging activity with an IC50 value of 10.21 µg/mL, whereas an IC50 of 77.44 µg/mL against DPPH+ radicals was found. C. speciosa fixed oil inhibited lipase with an IC50 value of 127.57 µg/mL. The present investigation confirmed the functional properties of C. speciosa fixed oil, and proposes its use as valuable source of bioactive constituents.

The Volatile Composition and Antibacterial Activity of Leaves of Chorisia Speciosa

“…Previously, Chorisia speciosa has been used as a synthetic reserve for various fatty acids including linoleic acid and palmitic acid etc. [9] but this phytochemical profile highlights the potential to isolate industrially important caryophyllene and bicyclogermacrene from the leaf essential oil. Caryophyllene is the most abundant component found in essential oil of Chorisia speciosa.…”

“…[37] Its fixed oil is known to exert anti-obesity and hypoglycaemic effects which suggests the use of its edible oil in preventing obesity and related disorders. [9] In this study, antibacterial evaluation of essential oil of Chorisia speciosa against three pathogenic microbes was evaluated and it showed highest activity against S. aureus (25 mm), and then against E. coli (15 mm) whereas no activity was found against S. typhi at the dose level of 3.64 mg presenting its stem potential as shown in Table 3. However, in comparison, the positive control showed a strong activity at a dose value of 25 µg against S. aureus (27 mm), S. typhi (22 mm) and E. coli (20mm), hence the essential oil activity was considered as moderate against S. aureus and weak against E. coli, taking into account the difference in dose values and their zones of inhibition.…”

Systematics, Phytochemistry, Biological Activities and Health Promoting Effects of the Plants from the Subfamily Bombacoideae (Family Malvaceae)

“…The cyclopropenoid fatty acids, malvalic acid and sterculic acid, have been identified in A. digitata [ 92 , 93 , 94 ], A. fony [ 94 ], and Bombax oleagineum , C. acuminata , and C. pentandra [ 61 ]. Recently, the seeds’ n -hexane extract of C. speciosa from Italy showed linoleic acid (28.22%) and palmitic acid (19.56%) as the most abundant fatty acids [ 95 ]. Percentages of 16.15 and 11.11% were found for malvalic acid and sterculic acid, respectively.…”

The Essential Oil Compositions of Three Teucrium Taxa Growing Wild in Sicily: HCA and PCA Analyses

“…scordioides have been recently published [ 20 ]. Consequently, in the frame of our ongoing research on Sicilian plants [ 21 , 22 , 23 , 24 ], and in order to improve the knowledge on genus Teucrium , we decided to investigate the chemical compositions of the other three Sicilian taxa of Teucrium , which have never been analyzed: T. flavum , belonging to Section Chamaedrys , and T. montanum and T. capitatum , belonging to Section Polium . We also screened the reported literature in order to find data concerning the chemical composition of their essential oils and we performed Hierarchical Cluster Analysis (HCA) and Principal Component Analyses (PCA) in order to find a similarity among the Sicilian accessions and the other taxa belonging the same species studied so far.…”
