Phytochemical studies of leaves and roots of the plant EchiumpycnanthumPomel (family Boraginaceae) revels thepresence of Flavonoids, Tannins, Quinones, Alkaloids, Saponins, Stérols and absence of Anthocyanes and Coumarines.

(Morphology and histochemistry of glandular trichomes of Cordia verbenacea DC. (Boraginaceae) leaves). The objective of this work was to study, using light and fluorescence microscopy and scanning electron microscopy, the morphology and secretory products of glandular trichomes of Cordia verbenacea DC. (Boraginaceae), known as ‘baleeira’, a species used in folk medicine as anti-inflammatory, an...

The methanolic extract of the whole plant of Echium glomeratum Poir. (Boraginaceae) has afforded five pyrrolizidine alkaloids, three that were (7S, 8R)-petranine (1), (7S, 8S)-petranine (2), and (7R, 8R)-petranine (3a) or (7R, 8S)-petranine (3b), comprising a tricyclic pyrrolizidine alkaloids subclass; and two that were known but to the species: 7-angeloylretronecine (4) and 9-angeloylretroneci...

The UHPLC-QToF-MS analysis of pyrrolizidine alkaloids (PAs) from various parts of 37 botanicals and 7 products was performed. A separation by LC was achieved using a reversed-phase column and a gradient of water/acetonitrile each containing formic acid as the mobile phase. MS-MS detection was used because of its high selectivity, and ability to provide structural information. Free base and N-ox...

Various plant seeds have received little attention in fatty acid research. Seeds from 30 species mainly of Boraginaceae and Primulaceae were analysed in order to identify potential new sources of the n-3 PUFA α-linolenic acid (ALA) and stearidonic acid (SDA) and of the n-6 PUFA γ-linolenic acid (GLA). The fatty acid distribution differed enormously between genera of the same family. Echium spec...

During the preparation of the Vascular Flora of the Marquesas Islands a new endemic species of Heliotropium L. (Boraginaceae) has come to light and is described herein: Heliotropiumperlmanii Lorence & W. L. Wagner. It is known only from the island of Eiao and appears most closely related to Heliotropiummarchionicum Decne., also endemic to the Marquesas and known from Nuku Hiva. An amended descr...

The aerial parts of Coldenia procumbens Linn. (Boraginaceae) are used in indigenous systems of medicine. The market sample is in the form of small pieces or nearly powdered, from which the morphological and anatomical characters are unable to study for the identification and conformation of its authenticity. The present study of physicochemical characteristics like physical constant values, beh...

Long-distance dispersal seems to be the main biogeographic event responsible for intriguing distribution patterns in plant groups in which sister taxa are separated by thousands of kilometers of distance across oceans and continents. The biotic and abiotic mechanisms behind such dispersal events are poorly understood and many attempts have been made to explain how plants can manage to disperse ...
