Chemical constituents and antimicrobial properties of the essential oil and ethanol extract from the stem of Aglaia odorata Lour.

Abstract

The stem-derived essential oil of Aglaia odorata Lour. was obtained by hydrodistillation using a Clevenger-type system. Gas chromatography-mass spectrometry analysis of the oil revealed the identification of 39 compounds, representing 76.4% of the oil; germacrene D (20.3%), α-humulene (17.1%), α-himachalene (12.7%) and β-caryophyllene (10.2%) were the major components. Ar-turmerone (1) and eichlerialactone (2) were isolated from the stem oil and ethanolic stem extract of this plant species, respectively. Antimicrobial activities of the oil and ethanol extract were tested against both Gram-positive and Gram-negative bacterial strains including Bacillus cereus ATCC 11778, Staphylococcus aureus ATCC 25923, Acinetobacter baumannii ATCC 19606 and Escherichia coli ATCC 25922, as well as three rice fungal pathogens Bipolaris oryzae, Pyricularia oryzae and Rhizoctonia solani using broth microdilution method. The oil and 1 exhibited significant antifungal activity against the three rice pathogens tested, whereas 2 exhibited good antibacterial activity against both the Gram-positive pathogens tested.

Properties and limits of some essential oils: chemical characterisation, antimicrobial activity, interaction with antibiotics and cytotoxicity

“…In our study, this oil demonstrated only poor antibacterial and antifungal activity (Table S1). On the contrary, low percentages of borneol and α-pinene in Ampelopsis megalophylla as reported by Xie et al (2014) and caryophyllene (Joycharat et al 2014) show high microbiological activity. TTO which exhibited MIC values of 3.12 mg/ml.…”

Phytochemical Profiling and Antibacterial Efficacy Screening of Aglaia Malabarica Sasidh

“…The phytochemical constituents of several other species of Aglaia have been reported earlier [8][9][10][11]. Most researches on the bioactivities of various species of Aglaia, like molluscidal, anti-inflammatory, insecticidal and antimicrobial activities have been supported with their chemical constituents [12][13][14] and this reveals the importance of the phytochemicals of this particular genus in therapeutics.…”

The complete chloroplast genome sequence of Aglaia odorata

“…The flowers of A. odorata are used to perfume clothes (Janprasert et al 1992). The extracts from A. odorata has antimicrobial properties (Joycharat et al 2014). It has been used as a traditional herb to treat heart disease, bruises, traumatic injury, and pyresis (Kato-Noguchi et al 2016).…”
