ABSTRACf Qualitative and quantitative wood features are reported for 38 species representing 22 genera, including the scandent genera Mendoncia and Thunbergia. Woods of Acanthaceae are characterized by relatively narrow vessels with simple perforation plates and alternate lateral wall pitting, septate libriform fibers, scanty vasicentric axial parenchyma, rays both multiseriate and uniseriate, ...

More than a decade of phylogenetic research has yielded a well-sampled, strongly supported hypothesis of relationships within the large ( > 4000 species) plant family Acanthaceae. This hypothesis points to intriguing biogeographic patterns and asymmetries in sister clade diversity but, absent a time-calibrated estimate for this evolutionary history, these patterns have remained unexplored. Here...

Original meiotic chromosome counts are presented for 39 species in 15 genera of Acanthaceae from Belize, Costa Rica, Ecuador, Mexico, Panama, the United States, and Venezuela. These reports include the first counts for 20 species representing 10 genera of the family, including the first chromosome number documented for the genus Poikilacanthus. Counts for 15 species confirm numbers previously r...

Secondary metabolites, DIBOA, HBOA, 7-OH-HBOA and BOA, were isolated and quantified from S. dulce (Nees), a native species in Chile belonging to the Acanthaceae family. The highest DIBOA and HBOA contents were determined in leaves (9.25 mmol kg(-1) fr. wt) and root (6.81 mmol kg(-1) fr. wt), respectively. Aglycones, 7-OH-HBOA and HBOA, were isolated together from root extracts of Acanthaceae sp...

Photochemical studies of leaf of the herbs Justicia tranquebariensis. (Acanthaceae) carried out in the presence of phytosterols, flavonoids, Glycosides and absence of triterpenoids, alkaloids, saponins tannins have been reported in this herb for the first time.

BACKGROUND A variety of plants in Acanthaceae have long been used in traditional Thai ailment and commercialised with significant economic value. Nowadays medicinal plants are sold in processed forms and thus morphological authentication is almost impossible. Full identification requires comparison of the specimen with some authoritative sources, such as a full and accurate description and veri...

The Acanthaceae family is an important source of therapeutic drugs, and the ethnopharmacological knowledge of this family requires urgent documentation as several of its species are near extinction. Justicia is the largest genus of Acanthaceae, with approximately 600 species. The present work provides a review addressing the chemistry and pharmacology of the genus Justicia. In addition, the bio...

Morphological, microscopical and phytochemical studies of root and stem of the herb Peristrophe bicalyculata (Acanthaceae) were carried out. Presence of coumarins, alkaloids, potassium chloride (stem and root), saponins and a free sugar (root) have been here in this herb for the first time.
