چکیده
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 Tinospora cordifolia (Willd.) was prepared for the first time and it was found to be asymmetric. The ideogram confirms the karyotypic formula K (n=11) = 9M+1Sm+1St.

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...

Tinospora cordifolia is used in Ayurveda as "Rasayanas" to improve the immune system and the body resistance against infections. Polysaccharides are the main constituents which are considered to be responsible for immune enhancement. In this study, immunomodulatory activity of three polysaccharide enriched fractions was evaluated using the polymorphonuclear leukocyte function test. Sugar compos...

Identified germplasm is an important component for efficient and effective management of plant genetic resources. Traditionally, plant identification has relied on morphological characters like growth habit, floral morphology like flower colour and other characteristics of the plant. Studies were undertaken for identification and genetic variation within 15 clones of Tinospora cordifolia throug...

Ethanol extracts of Ocimum sanctum Linn. and Tinospora cordifolia (Willd.) Miers ex Hook. f. & Thoms. were included for the present in vitro study. Pepsin was used as a substitute for HIV-protease to evaluate inhibitory activity of these extracts, as pepsin has close resemblance with HIV-protease in proteolytic activity. Extracts of O. sanctum and T. cordifolia showed potent inhibitory activity...

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 inv...
