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.

Heterostyly has been viewed as both an antiselfing device and a mechanism that increases the proficiency of pollen transfer between plants. We used experimental manipulation of the morph structure of garden populations of self-compatible, tristylous Eichhornia paniculata to investigate the function of floral polymorphism. Outcrossing rates (t), levels of intermorph mating (d), and morph-specifi...

A new phenylpropanoid glycoside (1), and two new coumarin glycosides (2, 3), together with two known compounds (4, 5), have been isolated from the stems of Hydrangea paniculata Sieb. Their structures have been determined by spectroscopic and chemical methods. Furthermore, compound 1 (50 μM) exhibited significant hepatoprotective activity against N-acetyl-p-aminophenol (APAP)-induced HepG2 cell ...

A large number of specimens used as original material for the description of new species were destroyed in the bombing of the Berlin-Dahlem herbarium, B, in 1943. Six lectotypes are designated here for Cordia discolor Cham., Cordia multispicata Cham., Cordia tobagensis Urb. and its variety broadwayi Urb. in the Cordiaceae and for Tournefortia paniculata Cham. and Tournefortia ulei Vaupel in the...

Antivenom activities of the alcoholic extracts of three species of Andrographis wall, were measured at a concentration of 10,25,50,75 and 100 μg/ml by in vitro assay of HRBC membrane lysis. All the extracts were found to be effective in the inhibition of in vitro HRBC lysis. The maximum antivenom activity was found in the alcoholicextract of Andrographis paniculata Nees.

Andrographis paniculata Nees, Andrographis alata Nees and Andrographis lineate Nees. (Acanthaceae) are important medicinal plants useful in the treatment of various human ailments. Nomenclatural confusion prevails with regards to these medicinal plants in India medical literature and vernacular nomenclature. This nomenclatural confusion has been clarified in the present paper.

Andrographolide isolated from Andrographis paniculata Ness (A and 1.40 mM induced DNA fragmentation and increased the percentage o breast cancer cell line was treated for 24 , 48 and 72 h. The results de induce apoptosis in TD-47 human breast cancer cell line in a time and increase expression of p53, bax , caspase-3 and decrease ex immunohistochemical analysis.

Infective hepatitis ia an acute inflamatory condition of liver. It is usually manifested in the form of Jaundice. In this clinical study Kalmegh(Andrographis paniculata Nees) was given in the decoction form to the patients of infective hepitis. The results were assessed on the basis of clinical and biochemical parameters. A marked symptomatic improvement in majority of the cases was observed. A...

To investigate the protective effect of the leaf extract of Andrographis paniculata (Ap) against ethanol induced liver toxicity in male albino rats. The liver toxicity was induced by the administration of ethanol to the animals at the optimum dosage of 7.9g/kg body wt., orally for 45 days. After induction of liver toxicity the aqueous plant extract of A.p was administered to the animal 250 mg/k...
