Kalmegh (Andrographis paniculata Wall. Ex Nees) crop as influenced by the application of farmyard manure (FYM) and inorganic phosphorus in typic torripsamments of Hisar
The growth attributes of kalmegh (plant height, number of primary branches, plant spread and dry weight of shoot) were enhanced significantly with the application of 12.5 mg P2O5 kg-1 soil. Application of farmyard manure (FYM) 12.5 t ha-1 significantly improved all the growth attributes significantly over control. However, 12.5 mg P2O5 kg-1 soil along with FYM 12.5 t ha-1 resulted in significantly the highest values of...

Phytochemical composition, in vitro antioxidant and anticancer activities of quercetin from methanol extract of Asparagus cochinchinensis (LOUR.) Merr. tuber
Five compounds including quercetin (AC01), asparagine (AC02), sucrose (AC03), β-sitosterol-3-O-β-D-glucopyranoside (AC04) and β-sitosterol (AC05) were isolated from the methanol extract of Asparagus cochinchinensis (Lour.) Merr. tuber collected in Ba Ria–Vung Tau Province of Vietnam. Their structures were elucidated by NMR (1D and 2D-NMR). Quercetin (AC01) was subjected to the assay for antioxidant...

Chemical diversity and leishmanicidal activity of Manekia obtusa Miq (Piperaceae)
Piperaceae species have long been used for therapeutic purposes, a reason for the great interest in their use as a source of raw material in phytochemical studies. The aim of this work is to investigate the chemical composition and biological potential of Manekia obtusa Miq, a native rare Piperaceae species in Brazil. Phytochemical studies of nonpolar extract from leaves of M. obtusa led to the isolation and...

Induction of callogenesis and rhizogenesis in Perovskia abrotanoides Karel., a little known medicinal plant
The present study was carried out to investigate in vitro callogenesis and direct rhizogenesis of Perovskia abrotanoides Karel. for the first time. This medicinal plant grows in various regions of Iran. Leaf explants were incubated on Murashige and Skoog (MS) medium supplemented with different concentrations and combinations of auxins like IAA, IBA and NAA (0.5 to 4 mg/L) with cytokinins like Kin and BA (0.1 to 0.75...
