Essential oil obtained from Maclura triscuspidata fruit has been reported to have functional properties. This study aimed at determining chemical compositions and antioxidant activities of steam-distilled essential oil (SDEO) and glycosidically bound aglycone fraction (GBAF) isolated from fully ripe M. triscuspidata fruit. SDEO was isolated by simultaneous steam distillation and extraction (SDE). GBAF was prepared by Amberlite XAD-2 adsorption of methanol extract, followed by methanol elution and enzymatic hydrolysis. Both fractions were analyzed by gas chromatography–mass spectrometry (GC–MS). A total of 76 constituents were identified from both oils. Apart from fatty acids and their esters, the SDEO contained p-cresol in the highest concentration (383.5 ± 17.7), followed by δ-cadinene (147.7 ± 7.7), β-caryophyllene (145.7 ± 10.5), β-ionone (141.0 ± 4.5), n-nonanal (140.3 ± 20.5), theaspirane A (121.3 ± 4.5) and theaspirane B (99.67 ± 9.05 µg/g). Thirteen carotenoid-derived compounds identified in the SDEO are being isolated from M. triscuspidata fruit for the first time. Out of the 22 components identified in GBAF, 14 were present only in the glycosidically bound volatiles. Antioxidant activity of the GBAF was higher than that of SDEO. These results suggest that glycosidically bound volatiles of M. triscuspidata fruit have a good potential as natural antioxidants.

Background: Rhus pentaphylla Desf. (Anacardiaceae) widely grown in Algeria, is an underutilized plant and remains poorly studied. To investigate for the first time, the chemical composition profile of essential oil and hydrosol extract; besides Total Phenolic (TPC), Flavonoid (TFC) and Condensed Tannins Contents (CTC) of fruits, leaves and roots, the fatty acid composition was assessed. The radical scavenging activity of R. pentaphylla extracts was then evaluated. Methods: Essential oil and hydrosol extract were isolated respectively by hydrodistillation and liquidliquid- extraction from the aerial parts of R. pentaphylla. The antioxidant activity was evaluated using 2,2-Diphenyl-1-Picrylhydrazyl (DPPH) radical and ferric reducing antioxidant power (FRAP). Chemical compositions of various extracts were investigated using Gas Chromatography (GC) and GC-Mass Spectrometry (GC-MS). Results: The results of GC and GC-MS analysis revealed 83 components in essential oil and 75 components in hydrosol extract representing respectively 96.9% and 92.5% of the total extract composition. The main constituents were hexadecanoic acid (31.5%) followed by spathulenol (14.9%) in the oil while the higher amount present in the hydrosol extract was of spathulenol (14.2%). Otherwise, 13 and 18 fatty acids were identified in roots and fruits respectively. The highest levels of TPC and CTC were found in roots extracts while the highest quantity of TFC has been recorded in the leaves extract. Besides, hydrosol extract was able to scavenge DPPH and FRAP free radicals more efficiently than essential oil. Conclusion: R. pentaphylla contains bioactive substances that could be used as a new promising source of antioxidant compounds in different applications.

Oxidation Effect

ABSTRACTAntioxidants have a function to scavenge and neutralize oxidation effect caused by free radicals by preventing the formation of radicals. Temu blenyeh (Curcuma purpurascens Bl) is one of the curcuma species which is still under-researched. Traditionally, temu blenyeh is used to treat stomachache, cough, itch, and skin infection. Some studies show that temu blenyeh extract had antioxidants activity and anti-cancer. The extract contains flavonoid, terpenoid, steroid, triterpenoid, essential oil. The study aimed to determine antioxidant activity of ethanol extract of temu blenyeh using DPPH method. Temu blenyeh was extracted by maceration with 96% ethanol solvent. The antioxidants activity test described that the value of IC50 was 48.697 ppm.

Sintoc (Cinnamomum sintoc Bl.) is a plant which is used as medicine. This plant has been known to have an analgesic antiinflamatory activity, therefore it is predicted to have an antioxidant activity. An investigation on antioxidant activity of sintoc essential oils and ethanolic extract of its cortex using ascorbic acid as standard has been carried out. Essential oils and ethanol extract of sintoc cortex was tested using DPPH (1,1-diphenyl-2-pikril-hidrazil) by measuring absorbance using visible spectrophotometer at 518 nm. The methods of this research were distillation of essential oils and extraction of sintoc cortex, determination of the essential oil and extract concentrations required for 50% inhibition of DPPH radical scavenging effect (IC50) with ascorbic acid as the possitive control. The variation concentration  of essential oils are 15, 5, 1, 0.1, 0.5 ppm and 25, 20, 17, 15, 10 ppm for ethanolic extracts. The results showed that the essential oil showed antioxidant activity with IC50 value was 16.29 ppm (5 times lower than ascorbic acid) and then ethanolic extract showed IC50 value 38.89 ppm (11 times lower than ascorbic acid, IC50 of ascorbic acid was 3.35 ppm).

Yield Quality

Buds and flowers of clove (Syzygium aromaticum L.) are economically important essential oil sources. The purpose of this study was to assess the yield, quality, and antioxidant activity of Zanzibar clove bud oil between three phenological stages (budding-3, full-budding, and flowering) in young (3-4 years) and mature trees (45 years). Chemical compositions of the oil were analyzed using GC-MS, and the physicochemical properties were measured based on SNI 06-4267-1996. Antioxidant activity was analyzed using the DPPH method. The results showed flowering buds of young trees produced higher yield (16.73%) than that of the mature ones (14.93%). The GC-MS analysis showed that the main bioactive compound of clove oil was eugenol (68.05–82.38%), which is highest at the flowering stage in mature trees. Almost all of the clove bud oils met physicochemical properties standard required by the SNI 06-4267-1996. DPPH scavenging activity IC50 ranged 15.80–108.85 µg/mL, with the highest antioxidant activity at the flowering stage of young trees. The results indicate that clove at flowering stage produced the best essential oil ingredient, as well as the most efficient source of natural antioxidants with slight differences in quality between the young and mature trees.

The aim of the present study is to characterize chemical compositions and antioxidant, anticholinesterase and anti-tyrosinase activities of Ferula elaeochytris and Sideritis stricta essential oils. The hydrodistilled essential oils were analyzed by GC/FID and GC/MS. A total of thirty-three and twenty-seven compounds representing 99.6 % and 99.4 % were identified in F. elaeochytris and S. stricta, respectively. The main compounds of essential oil of F. elaeochytris were β-cubebene (21.3 %), caryophyllene oxide (17.5 %) and β-caryophyllene (14.9 %), while the major compounds of S. stricta essential oil were δ-cadinene (18.3 %), cubenol (17.6 %) and β-caryophyllene (14.4 %). The antioxidant activity was tested by β-carotene-linoleic acid, DPPH free radical scavenging, ABTS cation radical scavenging, CUPRAC and metal chelating assays. The essential oil of F. elaeochytris showed the highest antioxidant activity in all assays. Also, the anticholinesterase and anti-tyrosinase activities of essential oils were performed against acetylcholinesterase (AChE), butyrylcholinesterase (BChE) and tyrosinase enzymes. F. elaeochytris essential oil indicated the highest anticholinesterase and anti-tyrosinase activities as well. This is the first report describing antioxidant, anticholinesterase and anti-tyrosinase activities of essential oils of F. elaeochytris and S. stricta.
