Journal ArticleDOI
TL;DR: It is proposed that proline might be essential for improving salinity tolerance in some species/cultivars, but may not be relevant in others, and that comprehensive future research is needed to establish the proline exact mechanism by which it enhances plant salt tolerance.

195 citations


Journal ArticleDOI
TL;DR: Drought stress probably increases the methylchavicol and methyleugenol content, in part, through increasing the expression levels of CVOMT and EOMT, as well as the effect of drought stress on the essential oil compounds, which were investigated.

89 citations


Journal ArticleDOI
TL;DR: In the root exudate and root extracts of maize hybrid cv NK Falkone seven putative strigolactones were detected using UPLC-TQ-MS-MS and exhibited Striga hermonthica seed germination inducing activity just as the synthetic strIGolactone analog GR24.

77 citations


Journal ArticleDOI
TL;DR: From the obtained results, Argyranthemum pinnatifidum, Helichrysum melaleucum, and Phagnalon lowei are good candidates for further development of phyto-pharmaceutical preparations as complementary therapy for diabetes and obesity control.

70 citations



Journal ArticleDOI
TL;DR: The stress related increase of biosynthesis is not only due to a "passive" shift caused by the stress related over-reduced status, but also is due - at least in part-to an "active" up-regulation of the enzymes involved.

58 citations


Journal ArticleDOI
TL;DR: Nine hydrolyzable tannins, including three previously unknown and six artifacts, were isolated, together with thirty-nine known ones, from the fruits of Terminalia chebula Retz.

56 citations


Journal ArticleDOI
TL;DR: Five previously undescribed metabolites, including acetylquestinol, two prenylated indole 3-carbaldehyde derivatives, an anthranilic acid derivative and an isochromone derivative were isolated from the culture of the endophytic fungus Eurotium chevalieri.

54 citations


Journal ArticleDOI
TL;DR: An exhaustive map of natural occurrences of aurones their biosynthetic pathways and roles is drawn up, with the aim to link their original structural properties among flavonoids to their place in evolution and the selective advantages they bring to some of the most advanced taxa in the plant kingdom.

Journal ArticleDOI
TL;DR: Investigation demonstrated that targeting multiple tumor metabolic regulators might be one anti-glioma mechanism of streptodepsipeptide P11A, and downregulated expression of HK2, PFKFB3, PKM2, GLS, and FASN, important tumor metabolic enzymes.

Journal ArticleDOI
TL;DR: The structures of these compounds were unambiguously determined based on extensive NMR spectroscopic analyses, and the absolute configuration was resolved by CD analyses, X-ray crystallographic, chemical and Mosher's method.

Journal ArticleDOI
TL;DR: Five previously undescribed compounds including two triterpenoid aglycones, 3β,23-dihydroxy-1,12-dioxo-olean-28-oic acid, and three triter penoid glucosides cyclocarioside L-N, along with 17 known compounds were isolated from a CH3Cl-soluble extract of the leaves of Cyclocarya paliurus.

Journal ArticleDOI
TL;DR: The results indicated that terpenoids in the latex of E. peplus are rich and highly diversified, and might function as constitutive defense metabolites against insect herbivores and pathogens for the plant.

Journal ArticleDOI
TL;DR: Three previously undescribed isoflavone derivatives, 7-O-methylcorylifol A, 7 -O-isoprenylcory Lifolia A, and 7-Dihydro-12,13-epoxybakuchiol have been isolated from the fruits of Psoralea corylifolia, together with 9 known compounds.

Journal ArticleDOI
TL;DR: A literature review of terpenes, phenolic compounds, and other less common phytochemicals from H. italicum with regard to application of different separation methods is presented.

Journal ArticleDOI
TL;DR: Phytochemical profiles of newly discovered allohexaploid hybrid, here named Centaurium pannonicum, and its parental tetraploid species C. erythraea and rare C. compressum are described.

Journal ArticleDOI
TL;DR: In a search for new anti-HIV active leads from over several thousands of plant extracts, a potent plant lead is identified as Justicia gendarussa (Acanthaceae), a medicinal plant that has been used for the treatment of injury, arthritis and rheumatism in Asia.

Journal ArticleDOI
TL;DR: Penicillic acid displayed weak antibacterial activity against Staphylococcus aureus and Escherichia coli with equal MIC values of 128 μg/mL, and it was noncytotoxic towards African green monkey kidney fibroblast cells.

Journal ArticleDOI
TL;DR: To profile human health-related metabolites in a number of clones from 13 Solanum species, results from HPLC-DAD and LC-ESI-MS analyses highlighted a high interspecific variability in the level of metabolites analysed.

Journal ArticleDOI
TL;DR: Findings indicate that green plants were able to synthesize and inactivate BRs from the land-transition stage.

Journal ArticleDOI
TL;DR: Chemical investigation of the methanol extract of the fertile form of Roccella montagnei collected in Vietnam afforded twelve secondary metabolites, including five new montagnetol derivatives, orsellinylmontagnetols A-D and a furanyl derivative together with seven known compounds.

Journal ArticleDOI
TL;DR: The chemical composition of inflorescence odours of 80 species of Amorphophallus (Araceae) were determined by headspace-thermal desorption GC-MS, revealing evidence both of phylogenetic constraint and plasticity of odours and the evolution of some odour types is likely to have been influenced by ecological factors.

Journal ArticleDOI
TL;DR: Cloning of bornyl diphosphate synthase of lavender (LaBPPS) is reported, an enzyme that catalyzes the production ofBornyl dphosphate (BPP) and then by-products such as borneol or camphor, from an EST library and borneol could be one of the first monoterpenes to be synthesized in the Lavandula subgenus.

Journal ArticleDOI
TL;DR: In this paper, the authors analyzed the transcription levels of several steviol glycosides (SGs) related genes under several light treatments involved in GA biosynthesis and found that SG-related genes and SGs content are affected by light treatments known to affect the GA contents.

Journal ArticleDOI
TL;DR: The isolation of α-amino-β-methylaminopropionic acid from seeds of Cycas circinalis (now C. micronesica Hill) resulted from a purposeful attempt to establish the cause of the profound neurological disease, amyotrophic lateral sclerosis/parkinsonism/dementia, that existed in high frequency amongst the inhabitants of the western Pacific island of Guam.

Journal ArticleDOI
TL;DR: A phytochemical study of an extract from transformed root cultures of Nepeta teydea, induced by Agrobacterium rhizogenes, led to the isolation of the following new compounds: the sesquiterpene (-)-cinalbicol, the diter pene teydeadione, and a degraded C23-triterpene (teydealdehyde).

Journal ArticleDOI
TL;DR: Some differences were observed between the metallicolous and nonmetallicolous populations - the accumulation of metals was lower in the shoots and higher in the roots of the NM population, compared with the MZ and MC populations.

Journal ArticleDOI
TL;DR: Seven triterpenoid saponins, named ilexsaponin I-O, along with twelve known ones, were isolated from the roots of Ilex pubescens and seven compounds were shown to inhibit LPS-induced nitric oxide (NO) and prostaglandin E2 (PGE2) production by suppressing the expression of inducible NO synthase (iNOS) and cyclooxygenase-2 (COX-2), respectively, in
