The present study reports the chemical constituents, antioxidant, anticonvulsant and α-amylase activities of the aerial part of Cyperus rotundus collected in Cameroon. Phytochemical study leads to the isolation of six known compounds alongwith lupeol (1), stigmasterol (2), tetracosanoic acid (3), a mixture of β-sitosterol (4a) and stigmasterol (4b), ursolic acid (5) and saikogenin F (6). Compounds 3, 5 and 6 were isolated for the first time from this species. The structures of these compounds were determined using spectroscopic analysis including 1D and 2D NMR, mass spectrometry and comparison with the literature data. Biological activities carried out on the extracts showed that the methanol extract exhibited good antiradical scavenging activity against DPPH radical (IC50 = 2.873 μg/mL) and very good ferric reducing antioxidant power (FRAP) (IC50 = 7.535 μg/mL). It appeared that the mixture of hexane and ethyl acetate extract at the dose 100 mg/kg protected 66% of mice against convulsion induced by the pentylenetetrazol and 50% of protection when using picrotoxin at the same dose. All the extracts and compounds from this plant showed no inhibition against α-amylase related to antidiabetic activity.

AbstractA new sesquiterpene, chlorantholide G (1), a new sesquiterpene dimer, elatiolactone (2), and 2 new diterpenes, elatiorlabdane B (3) and elatiorlabdane C (4), together with 51 known compounds, were isolated from the aerial parts of Chloranthus elatior. The new structures including their absolute configurations were mainly established by mass spectrometric, NMR, and electronic circular dichroism experiments. All isolated compounds were tested for their anti-hDHODH activity. (4S,6R)-4-hydroxy-6-isopropyl-3-methylcyclohex-2-enone (5) and (4S,5R,9S,10R)-8(17),12,14-labdatrien-18-oic acid (29) were the most active compounds with IC50 values of 18.7 and 30.7 µM, respectively.

Diabetes is one of the most dangerous metabolic disorders, with high rates of mortality worldwide. Since ancient times, medicinal plants have been used in traditional medicine to treat many diseases, including diabetes and its related complications. Plants are widely accepted, affordable, and perceived to have minimal adverse side effects. The Lamiaceae family is a potential source of therapeutic agents for the management of metabolic disorders, including diabetes. Hence, this review paper summarizes the antidiabetic use of Lamiaceae species in folk medicine globally. Furthermore, we present the antidiabetic activities and phytochemical constituents of twenty-three (23) Lamiaceae species and the antidiabetic activity of some notable chemical constituents isolated from some of these Lamiaceae species.

<em>Dracocephalum moldavica </em>L. and <em>Dracocephalum kotschyi </em>Boiss. are aromatic plants belonging to Lamiaceae family.<strong> </strong>The aim of this study was to identify the chemical components of <em>D. kotschyi<strong> </strong></em>and <em>D. moldavica</em> from Iran.<strong> </strong>The aerial parts of <em>D. kotschyi </em>were collected from (Kamu Mountain) Isfahan province and the aerial parts of <em>D. moldavica</em> were collected from Sari (Mazandaran province) North of Iran, during 2014. The essential oil was extracted by a Clevenger approach and analyzed using GC/MS. In total, 32 and 24 compounds were identified in the essential oil from the aerial parts <em>D. kotschyi<strong> </strong></em>and <em>D. moldavica</em>, respectively. The results obtained in our study indicated that the major components in the oil <em>D. kotschyi<strong> </strong></em>were limonene (23.56 %), carvacrol (14.65 %), γ-terpinene (12.99 %), α -pinene (12.62 %), 2-methyl-1-octen-3-yne (9.73 %), camphene (4.66 %), myrcene (3.65 %) and α -terpinene (3.12 %). The major constituents of the oil <em>D. moldavica</em> were geranyl acetate (36.62 %), geraniol (24.31 %), neral (16.25 %) and geranial (11.21 %). <em>D. kotschyi </em>is one of the important sources of limonene and<em> D. moldavica </em>is one of the important sources of geranyl acetate.

Pelargonium Graveolens

Pelargonium graveolens (Geranium) is a source of the finest quality of fragrance and its essential oils are used as antibacterial, and antifungal agents. The aim of the current research is to determine chemical constituents in the essential oil of P. graveolens by GC-MS and evaluate its antidiabetic activity via α-glucosidase inhibition assay. The chemical composition of P. graveolens essential oil was determined by GC/MS and its antidiabetic activity was assessed through inhibition of α-glucosidase enzyme in in-vitro models. GC-MS analysis determines 36 chemical components in the essential oil of P. graveolens leaves, and citronellyl isovalerate (10.41 %), menthol (9.61 %), linalool (8.63 %), p-menthone (6.31 %), and geranyl tiglate (4.99 %) were recorded as major constituents. The essential oil of P. graveolens leaves showed concentration dependant inhibition of α-glucosidase enzyme ranging from 28.13±1.41 to 74.24±2.53 µg/mL for concentration ranging from 31.25 to 1000 µg/mL. The IC50 values for of P. graveolens and acarbose were found as 93.72±4.76 and 80.4±2.17 µg/mL, respectively against the α-glucosidase enzyme. The study finding explores the chemical components of P. graveolens growing in the Iraqi Kurdistan region and scientifically supported its possible use in diabetic patients for controlling postprandial hyperglycemia.

Protium aracouchini (Aubl.) Marchand [sin Icica aracouchini Aubl.], which occurs in the Adolpho Ducke Forest Reserve, in the Brazilian Amazon, was evaluated for the presence of galls, for resin exudation and the composition of the essential oils from the aerial parts and the resin. The experiment to stimulate the exudation of resin from the trunk was conducted using a 2-chloroethylphosphonic acid solution. The resin produced after 40 days and the aerial parts had their essential oils extracted in a Clevenger apparatus and the volatile chemical constituents were analyzed using GC/MS. The non-oxygenated sesquiterpenes α-copaene (21.15%) and α-gurjunene (13.69%), in addition to the oxygenated sesquiterpene spathulenol (10.32%), were detected as the majority constituents of the essential oil of the leaves, and a concentration similar to that of α-gurjunene was found in the branches (13.28%). The resin essential oil showed a high concentration of hydrocarbon monoterpenes (76.49%) with a predominance of α-pinene (17.57%) and limonene (46.11%). Four gall morphotypes were found associated with this species. The present study reports for the first time information on the volatile constituents and the resinous potential of P. aracouchini, and registers the morphotypes of the galls that help in the taxonomy of the species.
