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...

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...

Background:Aframomum danielli is used in ethno-medicine for the treatment of several ailments and as a traditional food spice. Methods: The hydro-distilled leaf, stem, seed, rhizome and pod volatile oils of A. danielli were subjected to gas chromatography-mass spectrometry (GC-MS) analysis. Free radical scavenging capacity of the volatile oils was determined using 2,2-diphenyl-1-picrylhydrazyl ...

The dried rhizome of Belamcanda. chinensis (L.) DC. is an important traditional Chinese medicine. Previous chemical and pharmacological investigations indicated that flavonoids may be responsible for the bioactivity of the herb. In this paper, the effects on the contents of twelve flavonoids in the three subunit parts of the rhizome of B. chinensis during the thermal drying process under treatm...

Vegetative reproduction is a form of asexual propagation in plants. A wide range of plants develop rhizomes, modified stems that grow underground horizontally, as a means of vegetative reproduction. In rhizomatous species, despite their distinct developmental patterns, both rhizomes and aerial shoots derive from axillary buds. Therefore, it is of interest to understand the basis of rhizome init...
