Clonal plants have been shown to successfully survive in stressful environments, including salinity stress, drought and depleted nutrients through clonal integration between original and subsequent ramets. However, relatively little is known about whether clonal integration can enhance the performance of clonal plants under alkalinity stress. We investigated the effect of clonal integration on ...

Six tetraploid Alstroemeria clones were micropropagated by rhizome multiplication, a system whereby the shoots were cut off from the rhizome and discarded. In a three-week subculture interval, the average rhizome multiplication rate for all genotypes was 2.3. In one selected genotype the discarded shoots were used to initiate another micropropagation system: the leafy explant micropropagation s...

Hedychium spicatum (Ham-ex-smith) belongs to family zingiberaceae, is a perennial rhizomatous herb. It grows throughout subtropical Himalaya in the Indian state of Assam, Arunachal Pradesh and Uttarakhand with in an altitudinal range of 1000 to 3000 m. It is tall stout herb with fleshy rhizomes, thick straight stem with broadly lanceolate leaves. H. spicatum rhizome is mentioned as shati in Ayu...

Potentilla species have been used in traditional medicine in the treatment of different ailment, disease or malady. Potentilla reptans (P. reptans) has been scarcely studied. The aim of this study was to test antioxidant and anti-inflammatory activity of P. reptans aerial part and rhizome. DPPH assay was used to measure antioxidant activity of aqueous plant extracts. Anti-inflammatory effect wa...

Lagenandra ovata (Linn.) Thw. syn. L. toxicaria Dalz. of Araceae family was evaluated for antibacterial activity against the Gram positive bacterium, Staphylococcus aureus and the Gram negative bacteria, Escherichia coli, Klebsiella pneumoniae, Proteus mirabilis, P. vulgaris and Pseudomonas aeruginosa. Methanol extract of the rhizome and the oil fractions obtained from the methanol extract thro...

Phytochemical screening and their antibacterial activity of plant are important parameters which lead to the isolation of new and novel compounds. Cryptocoryne spiralis (Retz) Fischer ex Wydler var. spiralis (CSS) and Cryptocoryne retrospiralis (Roxb) Kunth (CR), leaf and rhizome have been selected for phytochemical screening to identify the different classes of secondary metabolites. Antibacte...

Curcuma angustifolia also known as ‘haledo’ is commonly found in Sikkim and has many medicinal uses and has been used traditionally since ancient ages. Its rhizome is aromatic and the solvent extract of the rhizome has free radical scavenging activity which was carried out in this study by 2,2-diphenyl-1-picrylhydrazyl DPPH. Hot methanol extract and cold methanol extract of the dried powder of ...

The microscopic and macroscopic characters of the rhizome of Curcuma domestica Val. were studied. The behavior of the powdered drug in the presence of various chemicals was also studied. Preliminary phytochemical screening on the various extracts of the rhizome was done in order to ascertain the various chemical constituents present. These studies were carried out to identify this plant for fut...
