Glycosyl composition of a polysaccharide from Tinospora cordifolia (Willd.) Miers
نویسنده
چکیده
Hook. f. & Thoms. (Menispermaceae), which is a succulent climbing shrub distributed throughout most of India, has been reported (1). Polysaccharides are often subjected to different chemical modifications in order to gain information on their sequences and possible configurations. Methylation analysis has proven to be valuable in following the outcome of such modifications. The present work involves determination of glycosyl linkages present in the polysaccharide and thereby suggesting the possible sequence of monosaccharides.

Karyotypic analysis of Tinospora cordifolia (Willd.) was carried out to determine the chromosomal classification by using “Aceto-orcine stain”. The plant is diploid with 2n=22 (18m+2Sm+2St) chromosomes and characterized in eleven pairs of chromosomes. The chromosomes are very short with a mean length 2.64 μm. and the total length of haploid complements was found 29.04 μm. The ideogram of Tinosp...

Guduchi has been widely used in the traditional medicine as an immunomodulator. Description of guduchi in Ayurvedic literature resemble with T. sinensis rather than with commonly available T. cordifolia and hence this may be used as substitutes for T. sinensis. T. cordifolia growing on Azadirachta indica commonly called Neem-guduchi has more immunomodulatory potential. Thus, immunomodulatory ac...
