The chemical constituents of leaf and peel essential oil of Citrus medica L. were analysed by gas chromatography mass spectroscopy (GC-MS). Nineteen components accounting for 99.9% of the oil were identified in leaf oil. The major constituents are erucylamide (28.43%), limonene (18.36%) and citral (12.95%). The peel oil contains forty three components accounting for 99.8% of the total oil and the major components are isolimonene (39.37%), citral (23.12%) and limonene (21.78%).

Ethanol (95%) and dichloromethane : methanol (DCM : M, 1 : 1 v/v) bark extracts (BEs) and leaf extracts (LEs) of authenticated Ceylon cinnamon (CC) were studied for antiamylase, antiglucosidase, anticholinesterases, and antiglycation and glycation reversing potential in bovine serum albumin- (BSA-) glucose and BSA-methylglyoxal models in vitro. Further, total proanthocyanidins (TP) were quantified. Results showed significant differences (p<0.05) between bark and leaf extracts for the studied biological activities (except antiglucosidase) and TP. BEs showed significantly high (p<0.05) activities for antiamylase (IC50: 214±2–215±10 μg/mL), antibutyrylcholinesterase (IC50: 26.62±1.66–36.09±0.83 μg/mL), and glycation reversing in BSA-glucose model (EC50: 94.33±1.81–107.16±3.95 μg/mL) compared to LEs. In contrast, glycation reversing in BSA-methylglyoxal (EC50: ethanol: 122.15±6.01 μg/mL) and antiglycation in both BSA-glucose (IC50: ethanol: 15.22±0.47 μg/mL) and BSA-methylglyoxal models (IC50: DCM : M: 278.29±8.55 μg/mL) were significantly high (p<0.05) in leaf. Compared to the reference drugs used some of the biological activities were significantly (p<0.05) high (BEs: BChE inhibition and ethanol leaf: BSA-glucose mediated antiglycation), some were comparable (BEs: BSA-glucose mediated antiglycation), and some were moderate (BEs and LEs: antiamylase, AChE inhibition, and BSA-MGO mediated antiglycation; DCM : M leaf: BSA-glucose mediated antiglycation). TP were significantly high (p<0.05) in BEs compared to LEs (BEs and LEs: 1097.90±73.01–1381.53±45.93 and 309.52±2.81–434.24±14.12 mg cyanidin equivalents/g extract, resp.). In conclusion, both bark and leaf of CC possess antidiabetic properties and thus may be useful in managing diabetes and its complications.

The leaf and stem essential oils of Artemisia monosperma from the desert region of central Saudi Arabia were analysed by gas chromatography-based techniques (GC–FID, GC–MS, Co-GC, LRI determination, database and literature search) using polar as well as non-polar columns, which resulted in the identification of 130 components, of which 81 were common to both oils. In the leaf oil 120 compounds were identified, while 91 were identified in the stem oil accounting for 98.4% and 99.7% of the oil composition, respectively. The major constituents of the leaf oil were β-pinene (50.3%), α-terpinolene (10.0%), limonene (5.4%) and α-pinene (4.6%), while the major constituents of the stem oil were β-pinene (36.7%), α-terpinolene (6.4%), limonene (4.8%), β-maaliene (3.7%), shyobunone (3.2%) and α-pinene (3.1%). The two oils showed an important qualitative similarity. However, some specific constituents (39 in the leaf oil and 10 in the stem oil) allow differentiation of the two essential oils.

Alternanthera pungens Kunth commonly called khaki weed is from the family Amaranthaceae. It is a herbaceous perennial plant that has stems prostrate, rarely rising and about 10-50 cm long. The work was carried out due to the scarcity of information on the volatile constituents from the plant leaves despite works on the flower and other parts. The extraction of the essential oils from the dried leaves was carried out by the hydro distillation method using an all-glass Clevenger apparatus. The extracted oils were then analyzed using gas chromatography-mass spectrometry (GC-MS). A total of twelve constituents' representing 93.39% of A. Pungens oil with a yield of 0.4% (v/w) was obtained. The analysis of the GC-MS results of the leaf oil showed that it was dominated by â-ionone (42.18%) and hexahydrofarnesyl acetone (15.53%), others in trace amounts include; methyl palmitate (6.13%), 1octadecyne (4.72%), undecane (3.73%), para-mentha-1, 3, 8-triene (3.65%), isophytol (3.21%), ?cadinene (3.06%), 1, 2-dimethyl cyclooctene (3.05%), para-cymene (2.96%), phytol (2.67%) and neophytadiene (2.50%). The  common classes of compounds present in the leaves oil are aceto monocyclic monoterpenoid (42.18%), sesquiterpenoids (18.59%), hydrocarbons (11.50%), diterpenoids (8.38%), monoterpenes (6.61%) and fatty acids (6.13%).The constituents and the compositional pattern of essential oil identified from the leaves of Alternanthera pungens grown in Nigeria differ quantitatively and qualitatively from previously reported member of the genus and the presence of sesquiterpenoid as one of the major components of the oils justify the traditional use of the plants in treating pains, headaches and inflammations.

The chemical constituents of essential oils obtained by hydrodistillation from Zingiber vuquangensis Lý N.S., Lê T.H., Trịnh T. H., Nguyễn V.H., Đỗ N.Đ. and Zingiber castaneum Škorničk. & Q.B. Nguyễn collected from Vu Quang National Park, Hà Tĩnh Province, Vietnam were analysed by GC and GC-MS. β-Pinene (24.7% and 26.1%) and β-caryophyllene (12.3% and 13.9%) were the main constituents in the leaf oil and stem oil of Zingiber vuquangensis. On the other hand the root oil contained bornyl acetate (20.9%), zerumbone (14.1%) and α-humulene (9.6%) while β-pinene (19.6%), 1,8-cineole (15.6%), α-pinene (10.3%) and β-caryophyllene (10.4%) were the significant compounds of the fruit oil. The leaf oil Zingiber castaneum was dominated by β-pinene (30.6%), α-pinene (9.5%), β-caryophyllene (9.4%) and bicycloelemene (9.1%). The compounds occurring in higher quantity in the stem oil were β-caryophyllene (14.7%), δ-cadinene (9.8%), bicycloelemene (8.4%) and α-cubebene (7.8%). However, camphene (15.1%), 1,8-cineole (13.6%), linalool (11.3%) and δ-3-carene (8.5%) were the main compounds of the root oil while ( E)-nerolidol (23.2%), ( Z)-9-octadecenamide (17.3%) and β-caryophyllene (10.8%) were the main constituents of the fruit oil. The essential oil did not exhibit noticeable antimicrobial effects. This is the first report on the volatile compositions of Z. vuquangensis and Z. castaneum.
