“…One article described the content of the main polyphenols, acylphloroglucinols, and naphthodianthrones extracted and analyzed by high performance liquid chromatography with diode-array detection and mass spectrometry (HPLC-DAD-MS) [36]. One of the articles regarding Pm described the presence of phenols, flavonoids, and tannins [37], another the iridoids and flavonoid glycosides [38], and the third investigated terpenes in the essential oil [39].…”

Major threats to the human lifespan include cancer, infectious diseases, diabetes, mental degenerative conditions and also reduced agricultural productivity due to climate changes, together with new and more devastating plant diseases. From all of this, the need arises to find new biopesticides and new medicines. Plants and microorganisms are the most important sources for isolating new metabolites. Lampedusa Island host a rich contingent of endemic species and subspecies. Seven plant species spontaneously growing in Lampedusa, i.e., Atriplex halimus L. (Ap), Daucus lopadusanus Tineo (Dl), Echinops spinosus Fiori (Es) Glaucium flavum Crantz (Gf) Hypericum aegypticum L: (Ha), Periploca angustifolia Labill (Pa), and Prasium majus L. (Pm) were collected, assessed for their metabolite content, and evaluated for potential applications in agriculture and medicine. The HPLC-MS analysis of n-hexane (HE) and CH2Cl2 (MC) extracts and the residual aqueous phases (WR) showed the presence of several metabolites in both organic extracts. Crude HE and MC extracts from Dl and He significantly inhibited butyrylcholinesterase, as did WR from the extraction of Dl and Pa. HE and MC extracts showed a significant toxicity towards hepatocarcinoma Huh7, while Dl, Ha and Er HE extracts were the most potently cytotoxic to ileocecal colorectal adenocarcinoma HCT-8 cell lines. Most extracts showed antiviral activity. At the lowest concentration tested (1.56 μg/mL), Dl, Gf and Ap MC extracts inhibited betacoronavirus HCoV-OC43 infection by> 2 fold, while the n-hexane extract of Pm was the most potent. In addition, at 1.56 μg/mL, potent inhibition (>10 fold) of dengue virus was detected for Dl, Er, and Pm HE extracts, while Pa and Ap MC extracts dampened infections to undetectable levels. Regarding to phytotoxicity, MC extracts from Er, Ap and Pm were more effective in inhibiting tomato rootlet elongation; the same first two extracts also inhibited seed cress germination while its radicle elongation, due to high sensitivity, was affected by all the extracts. Es and Gf MC extracts also inhibited seed germination of Phelipanche ramosa. Thus, we have uncovered that many of these Lampedusa plants displayed promising biopesticide, antiviral, and biological properties.

“…Sesquiterpenes were identified by comparing their Kovats retention indices (RI) with those from the literature ( Cavalli et al, 2003 ; Gkinis et al, 2003 ; Siani et al, 2004 ; Tzakou et al, 2004 ; Ghasemi et al, 2005 ; Li et al, 2006 ; Tepe et al, 2006 ; Vujisic et al, 2006 ; Pérez, Navarro & de Lorenzo, 2007 ; Saroglou et al, 2007 ; Basta et al, 2007 ; Hammami, Kamoun & Rebai, 2011 ), and comparing the mass spectra obtained with those stored in the NIST MS database and with mass spectra from the literature ( Chen et al, 2011b ; Liu et al, 2015b ; Xu et al, 2013 ). The Kovats retention indices were determined in relation to a homologous series of n-alkanes (C 7 –C 40 ) under the same operating conditions.…”

Sesquiterpenes are characteristic components and important quality criterions for agarwood. Although sesquiterpenes are well-known to be biosynthesized by sesquiterpene synthases (TPSs), to date, only a few TPS genes involved in agarwood formation have been reported. Here, two new TPS genes, namely, TPS9 and TPS12, were isolated from Aquilaria sinensis (Lour.) Gilg, and their functions were examined in Escherichia coli BL21(DE3), with farnesyl pyrophosphate (FPP) and geranyl pyrophosphate (GPP) as the substrate of the corresponding enzyme activities. They were both identified as a multiproduct enzymes. After incubation with FPP, TPS9 liberated β-farnesene and cis-sesquisabinene hydrate as main products, with cedrol and another unidentified sesquiterpene as minor products. TPS12 catalyzes the formation of β-farnesene, nerolidol, γ-eudesmol, and hinesol. After incubation with GPP, TPS9 generated citronellol and geraniol as main products, with seven minor products. TPS12 converted GPP into four monoterpenes, with citral as the main product, and three minor products. Both TPS9 and TPS12 showed much higher expression in the two major tissues emitting floral volatiles: flowers and agarwood. Further, RT-PCR analysis showed TPS9 and TPS12 are typical genes mainly expressed during later stages of stress response, which is better known than that of chromone derivatives. This study will advance our understanding of agarwood formation and provide a solid theoretical foundation for clarifying its mechanism in A. sinensis.

“…Essential oil was obtained and analyzed also in flowering plants from Greece [16], but the yield of essential oil is not reported. The composition of our samples differs from those of Greece: only α-pinene, γ-terpinene, thymol, (E)-caryophyllene, caryophyllene oxide, and tricosane are present in plants from both sites.…”

Prasium majus L. (Labiatae, Lamioideae) is considered a typical non-aromatic plant. In this work we examined the glandular trichomes present on leaves and inflorescences and the essential oils of plants growing along the Tuscan coast of Italy. The micromorphological study evidenced different types of trichomes responsible for the essential oil production. The essential oil compositions of leaves and flowers were analyzed by GC/MS and are here reported.
