Rhizosphere processes are known to modify uptake of elements from soil, but limited information is available for hyperaccumulators. We investigated labile Ni fractions and their kinetics replenishment in the rhizospheres Ni-hyperaccumulator Odontarrhena serpyliffolia, Ni-excluder Holcus lanatus bulk soils collected at same serpentine outcrop. Labile rhizosphere soil were evaluated using convent...

Andrographis paniculata (Burm. F.) Wall. Ex Nees (Family: Acanthaceae), commonly known as Kalmegh or ‘‘King of Bitters”, is one of the many traditionally known medicinal plants listed in WHO herbal Monograph [1]. It is a rich natural source of bioactive labdane diterpinoids like andrographolide, neoandrographolide, isoandrographanolide, andrograpanin, etc. Amongst them andrographolide is quanti...

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.

Two new flavonoids, 5, 7, 2', 5'-tetramethoxyflavanone (1) and 5-hydroxy-7, 2'-dimethoxyflavone (2), together with two known flavones, skullcapflavone I (3) and echioidin (4) were isolated from the whole plant of Andrographis rothii. The structures of the new compounds were established by extensive one- and two-dimensional (1D- and 2D-) NMR spectral studies.

Hydroalcoholic extract of Andrographis paniculata prevented isoproterenol induced increase in lipid peroxidation and increased the activities of antioxidant enzymes viz. super oxide dismutase, catalase, glutathione peroxidase and the levels of reduced glutathione in hearts. In addition, the extract also prevented the leakage of lactate dehydrogenase from heart and salvages the heart from isopro...
