Phytochemical Analysis and Biological Activities of the Ethanolic Extract of Daphne sericea Vahl Flowering Aerial Parts Collected in Central Italy
The ethanolic extract of Daphne sericea Vahl flowering aerial parts collected in Italy was found to possess radical scavenging against both DPPH• and 2,2′-azino-bis(3-thylbenzothiazoline-6-sulfonic acid (ABTS•+) radicals, with at least a 40-fold higher potency against the latter, suggesting a possible indirect antioxidant power of the extract.
A new diterpene and other compounds from the unripe female cones of Wollemia nobilis
The analysis evidenced the presence of a new derivative of sandaracopimaric acid together with rare diterpenoid derivatives and known compounds of chemosystematic and bioactivity relevance in the unripe female cones of Wollemia nobilis.
Phytochemical analysis on the leaves of Agathis microstachya J.F. Bailey & C.T. White.
The first phytochemical analysis on the leaves of Agathis microstachya J.F. Bailey & C.T. White collected in Rome was reported in this work and the presence of dactylifric acid in the whole Araucariaceae family was evidenced.
The genus Perovskia Kar.: ethnobotany, chemotaxonomy and phytochemistry: a review
This review paper was undertaken to integrate all the data published about the ethnobotany, phytochemistry and biological activities of species belonging to the genus Perovskia during the past decades to discuss compounds belonging to different classes of natural products worldwide.
Phytochemistry, Chemotaxonomy, and Biological Activities of the Araucariaceae Family—A Review
It is given a wide overview on the phytochemical profile of Wollemia genus, for the first time, and the ethnopharmacology and the general biological activities associated to the Araucariaceae species are singularly described.
Qualitative and semi-quantitative phytochemical analysis on the seeds of a new Nigella sativa L. population exemplar from Iran
The first phytochemical analysis on the seeds of Nigella sativa L. sativa collected from a new population in Iran is reported, carried out by means of classical column chromato...
Antiproliferative, antimicrobial and antioxidant properties of Cedrus libani and Pinus pinea wood oils and Juniperus excelsa berry oil
The analysis of essential oils from the woods of C. libani and P. pinea and from the berries of J. excelsa found several differences that were observed with respect to previous studie...
Plants adapted to arid areas: specialized metabolites
During drought stress, transcription factors and related pathways for biosynthesis of phenolics, flavonoids, anthocyanins as well as for stress jasmonate and abscisic acid stress hormones are activated.


Terpenoids and More Polar Compounds from the Male Cones of Wollemia nobilis
Several diterpenoids of chemosystematic relevance were recognized for the first time from the genus and/or from the Araucariaceae family, namely isocupressic acid, methyl (E)‐communate and sandaracopimaric acid; all these terpenoids are also endowed with interesting biological activities and may play a primary role in the self defence toward herbivores.
Iridoids of Chemotaxonomy Relevance, a New Antirrhinoside Ester and Other Constituents from Kickxia spuria subsp. integrifolia (Brot.) R.Fern.
The iridoid content showed a molecular pattern very similar to those reported for other taxa comprised in the Antirrhinae tribe of Plantaginaceae, thus providing an additional evidence that supports the current botanical classification of the Kickxia genus.
Phytochemical Profile of Wollemia nobilis Half-Matured Female Cones and Their Potential Ethnopharmacological and Nutraceutical Activities
A preliminary nutraceutical evaluation of the half-matured female cones of the rare species, Wollemia nobilis, showed a good nutr pharmaceutical potentiality but also some potential critical state mainly due to the occurrence of acetyl-isocupressic acid, which is quite known to have some adverse pharmacological effects.
Phytochemical analysis of the ethanolic extract of Agathis robusta (C. Moore ex F. Muell.) F.M. Bailey
The phytochemical analysis of the ethanolic extract obtained from the leaves of Agathis robusta revealed several pharmacological properties among which, the antibacterial, anti-inflammatory and protective ones are the most important and may explain why this species is used in the ethno-medicinal field.
Seaweed as a new source of flavone, scutellarein 4'-methyl ether
Phycochemical investigation of a red alga Osmundea pinnatifida (Hudson) Stackhouse, collected from Karachi Coast of Pakistan, led to the isolation of a flavone, which was assigned as Scutellarein
Bioactive Constituents of Juniperus turbinata Guss. from La Maddalena Archipelago
The essential oil appears to belong to a new chemotype compared to other Mediterranean juniper accessions, as it was favored by geographic isolation of the isles, and compound 8 showed powerful effects towards tumor cell lines, which make it a promising anticancer drug candidate.
