“…The volatile constituents found in this study corroborate the constituents that are commonly found in several plants of the Myrtaceae family and belonging to the Syzygium genus, such as Syzygium aromaticum (Raina et al, 2001), Guinea-Bissau (Noudogbessi et al, 2008), Syzygium densiflorum (Saranya et al, 2012), Syzygium calophyllifolium (Vignesh et al, 2013) and Syzygium benthamianum (Deepika et al, 2013).…”

The species Syzygium cumini, Syzygium malaccense and Syzygium jambos, belong to the family Myrtaceae and are popularly known, respectively, by jambolan, red jambo and yellow jambo. These species are used in traditional medicine to treat diabetes mellitus, asthma, bronchitis, diuresis, gastrointestinal and respiratory infections, properties antipyretic, anti-inflammatory, antirheumatic and several other uses. The objective of this work is to identify and quantify the volatile compounds in the leaves of S. cumini, S. malaccense and S. jambos. The volatile oils were obtained by hydrodistillation using Clevenger apparatus and analyzed by Gas Chromatography Coupled to Mass Spectrometry (GC-MS). It was possible to identify 44 compounds present in the volatile oils of the leaves, being 20 compounds of S. cumini, 9 compounds of S. malaccense and 15 compounds of S. jambos. The major compounds present in the species S. cumini were α-terpineol, β-caryophyllene and α-humulene; for the species S. malaccense were aristolochene, γ-himachalene and δ-amorphene; and for S. jambos species were β-cariophyllene, (E,E)-α-farnesene and cariophyllene alcohol. The species S. cumini, S. malaccense and S. jambos showed considerable differences in terms of volatile compounds, it is important to know their constituents in order to promote further studies focused on their medicinal potential.

“…The other terpenes produced include iso-longifolene (2 k ) and β-caryophyllene (2 d ), accounting for 12.5% of total peak area. There have been other studies that reported the detection of isoledene [ 10 – 12 ] in plants, and a putative isoledene synthase was predicted in the genome of Eucalyptus grandis [ 65 ]. However, EC12-ILS is the first isoledene synthase enzyme to be functionally characterized.…”

Endophytic fungi are ubiquitous plant endosymbionts that establish complex and poorly understood relationships with their host organisms. Many endophytic fungi are known to produce a wide spectrum of volatile organic compounds (VOCs) with potential energy applications, which have been described as "mycodiesel". Many of these mycodiesel hydrocarbons are terpenes, a chemically diverse class of compounds produced by many plants, fungi, and bacteria. Due to their high energy densities, terpenes, such as pinene and bisabolene, are actively being investigated as potential "drop-in" biofuels for replacing diesel and aviation fuel. In this study, we rapidly discovered and characterized 26 terpene synthases (TPSs) derived from four endophytic fungi known to produce mycodiesel hydrocarbons. The TPS genes were expressed in an E. coli strain harboring a heterologous mevalonate pathway designed to enhance terpene production, and their product profiles were determined using Solid Phase Micro-Extraction (SPME) and GC-MS. Out of the 26 TPS’s profiled, 12 TPS’s were functional, with the majority of them exhibiting both monoterpene and sesquiterpene synthase activity.

Context Syzygium densiflorum Wall. ex Wight & Arn (Myrtaceae) has been traditionally used by local tribes of the Nilgiris, Tamil Nadu, India, for the treatment of diabetes, however, no definitive experimental studies are available. Objective This study investigates the antidiabetic, antihyperlipidaemic and antioxidant activities of ethanol extract of S. densiflorum (EFSD) fruits in streptozotocin (STZ) and nicotinamide (NA)-induced diabetic rats. Materials and methods Acute oral toxicity and oral glucose tolerance were assessed in normal rats. The antidiabetic, antihyperlipidaemic and antioxidant activities were investigated in STZ À NAinduced diabetic rats. Diabetic rats were orally administered with glibenclamide (10 mg/kg b.wt), EFSD (200, 400 and 800 mg/kg b.wt) for 28 d. Further, changes in the blood glucose level (BGL), biochemical parameters, antioxidants were observed and histology of pancreas was performed.Results No toxicity and lethality were observed. Results of the following parameters are represented by treated versus disease control (STZ + NA) groups. BGL (161.33 ± 22.8 versus 476.17 ± 56.58 mg/dl), glycosylated haemoglobin (5.285 ± 0.19 versus 8.05 ± 0.55%), urea (40.32 ± 1.96 versus 75.37 ± 2.91 mg/dl), uric acid (1.2 ± 0.07 versus 2.16 ± 0.05 mg/dl), total cholesterol (89.3 ± 5.14 versus 139.7 ± 5.95 mg/dl) and triglycerides (79.65 ± 2.52 versus 108.9 ± 3.61 mg/dl) were significantly decreased, whereas haemoglobin (11.75 ± 0.73 versus 7.95 ± 0.42 g/dl), high-density lipoprotein cholesterol (14.2 ± 1.11 versus 6.97 ± 0.84 mg/dl), total protein (45%) and liver glycogen (87%) were significantly increased in EFSD-treated diabetic group. Significant changes were observed in the enzymatic and non-enzymatic antioxidants in EFSDtreated groups (p50.001). Histopathological examination showed the regeneration of b-cells in Islets of Langerhans. Conclusion This study confirms the antidiabetic, antihyperlipidaemic and antioxidant activities of S. densiflorum fruits. ARTICLE HISTORY
