Abstract The pollen of stingless bees is derived from flower pollen mixed with bee digestive enzymes and preserved with honey and nectar. In this study, the volatile compounds present in ethanolic bee pollen extracts (BPEs) from three species of the Malaysian stingless bee were analyzed using gas chromatography-mass spectrometry (GC-MS). Hydrocarbons, sugars and its derivatives, fatty acids, amino acids, alcohol, uridine, aldehyde and an unknown carbamate were detected. Mannitol, the main sugar compounds, represented 54.34% in Trigona thoracica, 39.11% in Trigona apicalis and 33.05% in Trigona itama. Propanoic acid and hexadecanoic acid were the main hydrocarbons present in the extract of Trigona apicalis (4.04%) and Trigona thoracica pollen (1.28%) respectively. The polyunsaturated fatty acids linoleic acid and α-linolenic acid were found in small amounts in all BPEs (0.07-1.11%). The chemical compounds found in BPEs had biological activities, thus bee pollen may be useful in traditional medicine and as a health supplement.

Abstract Several chemical compounds, e.g., linoleic and oleic acids, have been reported to be attractive to the pine wood nematode, Bursaphelenchus xylophilus, in previous studies. To examine the effects of fatty acids on the number of nematodes carried by Monochamus alternatus and Acanthocinus orientalis, unsaturated fatty acids (linoleic, oleic and hexadecenoic acids) and saturated fatty acids (palmitic and stearic acids) around the pupal chambers of individual beetles of the two species were analysed using gas chromatography-mass spectrometry. The number of nematodes carried by individual M. alternatus was large, averaging 1628 (range 2 to 27 200), whilst A. orientalis carried no nematodes. There was no difference in the concentration of linoleic acid around the pupal chambers of M. alternatus and A. orientalis, and the concentration of oleic acid around Monochamus chambers was less than that around Acanthocinus chambers. There were no clear significant relationships between the concentration of linoleic or oleic acids around Monochamus pupal chambers and the numbers of nematodes carried by individual Monochamus beetles emerging from the chambers. It was concluded that the concentration of unsaturated fatty acids around pupal chambers in wilt-killed pine trees could not explain the differences in the numbers of nematodes carried by M. alternatus and by A. orientalis, and the differences in the numbers of nematodes carried by individual Monochamus beetles.

Chemical constituents of essential oils (EOs) obtained from stem and root of Tephrosia purpurea (Linn.) Pers. and Ipomoea carnea Jacq. were investigated by Gas Chromatography-Mass Spectrometry (GC-MS). Total lipid and oil content was high in the stem than the root of T. purpurea and I. carnea. Essential oils extracted from the stem and root of T. purpurea and I. carnea showed 9 and 8 compounds respectively. Hexadecanoic acid was found to be the principal constituent of stem (69.61%) and root (46.97%) of T. purpurea while 70.61and 88.89% for stem and root, respectively in the case of I. carnea. The findings of the present study suggest that T. purpurea and I. carnea EOs can be used as a source of hexadecanoic acid which could be used for industrial purposes. The essential oils of T. purpurea and I. carnea showed strong repellent activity for males (-0.73 and -0.70 for T. purpurea and I. carnea stem EO respectively) than females (-0.63 and -0.59 for T. purpurea and I. carnea stem EO respectively) against banana pseudostem weevil Odoiporus longicollis. The results indicated that the active compounds of essential oils from stems of T. purpurea and I. carnea can be explored as natural repellents for control of Odoiporus longicollis.

Though many essential oils from citrus peels are claimed to have several medicinal functions, the chemical composition and biological activities of the essential oils of Citrus flowers have not been well described. Therefore, this study intended to investigate the chemical composition and anti-inflammatory potential of essential oils from C. unshiu flower (CEO) to support its purported beneficial health effects. The chemical constituents of the CEO, analyzed by gas chromatography-mass spectrometry (GC-MS), included γ-terpinene (24.7%), 2-β-pinene (16.6%), 1-methyl-2-isopropylbenzene (11.5%), L-limonene (5.7%), β-ocimene (5.6%), and α-pinene (4.7%). The effects of the CEO on nitric oxide (NO) and prostaglandin E2 (PGE2) production in lipopolysaccharide (LPS)-activated RAW 264.7 macrophages were also examined. The results indicate that the CEO is an effective inhibitor of LPS-induced NO and PGE2 production in RAW 264.7 cells. Additionally, CEO was shown to suppress the production of inflammatory cytokines including interleukin (IL)-1β, tumor necrosis factor (TNF)-α, and IL-6. Based on these results, CEO may be considered a potential anti-inflammatory candidate with human health benefits.
