Aerial Parts

Aromatic plants and essential oils have many applications in medicine, pharmaceuticals, cosmetics, and the food industry. The essential oil of the flowering aerial parts of Achillea grandifolia, obtained by hydrodistillation, was analyzed for its constituents and investigated for antimicrobial and radical scavenging activity. The essential oil was characterized by a high amount of oxygenated monoterpenes (72.7%) with 1,8-cineole (29.2%) and camphor (23.4%) being the most abundant. Sesquiterpenes were present in smaller quantities (4.8%). Antimicrobial activity was tested against eight ATCC bacterial strains and two ATCC strains of Candida albicans. The essential oil exhibited highly pronounced antimicrobial activity against Micrococcus luteus with a MIC value of 3.50 ?g/mL, as well as significant antimicrobial activity (<100 ?g/mL) against Staphylococcus aureus, S. epidermidis and Bacillus subtilis. Gram-negative bacteria Escherichia coli and Pseudomonas aeruginosa were resistant. Achillea grandifolia essential oil exhibited concentration-dependent antiradical activity against 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical with an SC50 value of 5.4 mg/mL. The TLC-DPPH assay revealed two main light yellow spots indicating components with anti-DPPH activity, which after isolation were identified as 1,8-cineole and camphor.

Background: The essential oil from the Acantholimon genus have been an integral part of the traditional food additive in Middle East. Most of the plants in Acantholimon genus have not been studied scientifically. The aim of this study is to investigate the chemical composition, antibacterial, insecticidal and anti-oxidant activities of three Acantholimon species including Acantholimon atropatanum, A. gilliatii and A. tragacanthium. Method: The essential oils of the aerial parts were extracted by hydrodistillation. Chemical constitutions were identified by gas chromatography- mass spectroscopy technique, also their toxicities were assessed against the two important grain products pests, Oryzeaphilus mercator and Tribolium castaneum. Antibacterial activity was assessed against the three foodborne bacteria that include Escherichia coli, Pseudomonas aeruginosa and Staphylococcus aureus based on the disc diffusion assay. Free-radical-scavenging property was identified based on 1, 1-diphenyl-2-picrylhydrazyl (DPPH) radical scavenging activity. Results: 2-hexahydrofarnesyl acetone was the main compound in A. gilliatii and A. tragacanthium, whilst farnesyl acetone, heptacosane and germacrene D were the principal components of A. atropatanum essential oil. These oils exhibited 40-90% mortality of O. mercator and/or T. castaneum at a dose of 12 μl/l air after 48h of exposure, and exhibited significant free-radicalscavenging property (RC50 = 3.7 × 10-3 - 8.3 × 10-3 mg/ml). The oils of A. tragacanthium and A. gilliatii showed a weaker antibacterial activity compared to A. atropatanum. Conclusion: A. atropatanum, A. gilliatii and A. tragacanthium essential oils had significant insecticidal and anti-oxidant properties. They also showed week to moderate antibacterial activity against P. aeruginosa and S. aureus.

Abstract. Syafrizal, Ramadhan R, Kusuma IW, Egra S, Shimizu K, Kanzaki M, Arung ET. 2020. Diversity and honey properties of stingless bees from meliponiculture in East and North Kalimantan, Indonesia. Biodiversitas 21: 4623-4630. Kalimantan Island in Indonesia is covered by tropical rain forests that are rich in biodiversity. Species, include a stingless bee (Trigona spp.). Recently, stingless bee beekeeping (Meliponiculture) in this region has become popular because the honey has a unique taste, a mix of sweet, sour, and bitter which is highly valued. The objective of this study was to determine the diversity of stingless bee species, the number of colonies, type of hive, and honey properties such as taste, acidity, color, phytochemicals, and radical scavenging activity or antioxidant in meliponiculture in selected areas of Eastern and Northern Kalimantan, Indonesia. The area studied included Samarinda, Balikpapan, Penajam, Bontang, Sangatta, and Tarakan. The study conducted by visiting the farmers, collecting the stingless bees species and bee products (honey, propolis, and bee pollen), pH, color and taste determination, phytochemical screening, and DPPH assay. We found 12 species, with Heterotrigona itama and Tetragonula laeviceps being the main ones cultivated by people in all research areas, except Balikpapan. We counted 111 colonies of T. laeviceps and 99 of H. itama in the meliponiculture. There were three types of hive used by farmers in meliponiculture. Most of the honey tasted sweet and sour with acidity or pH ranging from 3-4, and color from dark brown to light yellow. The phytochemicals contained tannin, alkaloid, flavonoid, triterpenoid, carotenoid, coumarin, saponin, and carbohydrate. The Tetragonula sarawakensis honey was the most potent in term radical scavengers. Our findings showed that stingless bee honey contains antioxidants with phytochemicals that are very useful for human health.

This study was undertaken to determine the antioxidant and antimicrobial effect of essential oil and extracts of Echinophora sibthorpiana Guss. (fam. Apiaceae) collected in Macedonia. The chemical composition of E. sibthorpiana essential oil was characterized by the presence of methyl eugenol (60.40%), p-cymene (11.18%) and ?-phellandrene (10.23%). The free radical scavenging activity of extracts and essential oil was evaluated by DPPH and ABTS assays. The aqueous extract of aerial parts exhibited the strongest scavenging activity (IC50=1.67 mg/ml); results of the ABTS test showed that the most effective was the ethanol extract of aerial parts (1.11 mg vit. C/g). The essential oil showed stronger antioxidant activity compared to hydroxyanisole, ascorbic acid and quercetin that were used in the DPPH and ABTS tests, respectively. The total phenolic and flavonoid concentrations in the extracts ranged between 38.65-60.72 mg GA/g, and 3.15-19.00 mg Qu/g, respectively. The antimicrobial properties of the extracts and essential oil were investigated using a micro-well dilution technique against human pathogenic strains. The results were comparable with the effects of the positive controls, streptomycin and fluconazole. These findings indicate that E. sibthorpiana extracts and oil can be used in preventive treatments and as an alternative for synthetic preservatives.

The essential oils of Blainvellea rhomboidea (Asteraceae) were obtained by hydrodistillation and analyzed by GC/MS and GC/FID. Initially, the essential oil from the aerial parts was investigated. From the 18 identified components, 5-indanol (14.5%) followed by p-cymen-8-ol (10.1%), β-caryophyllene (9.6%), caryophyllene oxide (9.6%), limonene (8.6%), terpinolene (7.8%), and spathulenol (7.7%) were the major constituents. The oil was tested against seven bacterial strains and the results showed significant antimicrobial activity. As a consequence, the essential oils from leaves and from flowers were analyzed separately. The major constituents of the leaf oil were terpinolene (21.2%), β-caryophyllene (19.2%), spathulenol (9.1%), caryophyllene oxide (7.4%), and bicyclogermacrene (7.1%), while the oil of the flowers contained terpinolene (28.1%), 5-indanol (16.3%), p-cymen-8-ol (15.3%) and limonene (14.7%) as prevalent compounds. The oils were tested against the same bacterial strains and the flower oil was the more active. These results indicated that the components of the essential oil from flowers seem to be responsible for the activity.

The chemical composition and antimicrobial activity of the essential oil of the Balkan endemic species Seseli rigidum Waldst. & Kit. (Apiaceae) was investigated. The monoterpene α-pinene was predominant in the volatile oil from aerial parts (57.4%) and fruit (23.3%). In the essential oil of the aerial parts limonene (6.7%), camphene (5.8%) and sabinene (5.5%) were also present in high amounts, and in the fruit oil, β-phellandrene (17.4%) and sabinene (12.9%). On the contrary, the root essential oil was composed almost entirely of the polyacetylene falcarinol (88.8%). The antimicrobial activity of the root essential oil was significant against Staphylococcus aureus, S. epidermidis, Micrococcus luteus and Enterococcus faecalis (MICs 6.25–25.00 μg/mL). Volatile constituents from the root strongly inhibited the growth of methicillin-resistant strains of S. aureus (MICs 6.25–50.00 μg/mL). Anti-staphylococcal activity can be attributed to the main volatile constituent of S. rigidum root, falcarinol.

<p>In the present study, aerial parts of <em>Nepeta cilicica</em> were hydro-distilled for the essential oil. Furthermore, air-dried plant materials were extracted with methanol. According to GC-MS results, 35 compounds were characterized in the oil (totally 92%). Caryophyllene oxide, β-caryophyllene and spathulenol (28.2, 8.9 and 4.2%) were found as main components of the oil. Sixteen compounds were detected by LC/MS, most of which were caffeoylquinic acid, luteolin and apigenin derivatives, in methanolic extract of the N. cilicica. Apart from DPPH radical scavenging activity, inhibitory effects on bacterial and yeast growth of essential oil and the methanolic extract were evaluated. Twenty-four different pathogenic bacterial and <em>Candida</em> strains were tested by M7-A7 and CLSI M27-A2 protocols respectively. The crude extract showed better inhibitory effects against bacteria strains than the essential oil. Both oil and the extract demonstrated strong inhibition on <em>C. tropicalis</em> at a concentration of 47.0 µg/mL (MIC).</p><p><strong>Video Clip of Methodology</strong>:</p><p>CLSI microdilution broth method: 3 min 46 sec   <a href="https://youtube.com/v/PBADMG2zG1c">Full Screen</a>   <a href="https://youtube.com/watch?v=PBADMG2zG1c">Alternate</a></p>
