Seed treatment with aqueous colchicine solution was carried out for induction of autotetraploidy in ashwagandha in four accessions (Shilpa, Acc. 17, Bydyanath and MWS-327). Increased stomatal size and decrease in stomata density aided in detection of autotetraploids. Among four ashwagandha accessions tried, Acc. 17 was more responsive for the induction of autotetraploids. Colchicine at 0.5 per ...

Biotransformation of artemisinin was investigated with two different cell lines of suspension cultures of Withania somnifera. Both cell lines exhibited potential to transform artemisinin into its nonperoxidic analogue, deoxyartemisinin, by eliminating the peroxo bridge of artemisinin. The enzyme involved in the reaction is assumed to be artemisinin peroxidase, and its activity in extracts of W....

Withania somnifera recently categorized as threatened plant of Rajasthan and known for its high medicinal value has been studied for existing genetic variations in four accessions collected from four different locations. From the present studies it is apparent that the gametic number of W. somnifera is n = 24 and 2n = 48. From the combined information generated by present author and earlier wor...

The neuroprotective effects of W. somnifera were studied on stressed adult female Swiss albino rats. Experimental rats were subjected to immobilization stress for 14 h and were treated with a root powder extract of W. somnifera available as Stresscom capsules (Dabur India Ltd). Control rats were maintained in completely, non stressed conditions. Thionin stained serial coronal sections (7 microm...

A double-blind, placebo-controlled study was conducted to evaluate the efficacy an ethanolic extract of Aswagandha (Withania somnifera), in patients with ICD-10 anxiety disorders. The sample comprised 39 subjects, of whom 20 received the drug and 19 received placebo. The two groups were sociodemographically and clinically similar at baseline. At 2 and 6 weeks follow-up, data from approximately ...

Withania somnifera (Ashwagandha) is a very revered herb of the Indian Ayurvedic system of medicine. It is useful for treating various kinds of disease processes and especially used as a nervine tonic. Withania somnifera (Ws) contain a wide array of active components including withaferin A, withanone and other flavonoids exhibiting strong anti-oxidant properties. Many scientific studies on Ws we...

Withania somnifera an Indian traditional medicinal herb, is known to possess antistress, antioxidant, analgesic, anti-inflammatory, cardioprotective, adaptogenic, antispasmodic, immunomodulatory and immunostimulant activities. Its other activities include anti-inflammatory, immunoregulatory, anti-tumor, anti-angiogenic, antiinvasive and chemopreventive effects. We investigated the antioxidant, ...

Withania somnifera (L.) Dunal known as Ashwagandha is commonly used in traditional Indian medicine system. It possesses immense therapeutic value against a large number of ailments such as mental diseases, asthma, inflammation, arthritis, rheumatism, tuberculosis, and a variety of other diseases including cancer. The therapeutic potential of W. somnifera is due to the presence of secondary meta...

Peripheral blood is an accessible adult stem cell source for both basic and applied research including clinical applications. Peripheral blood mononuclear cells (PBMCs) were reported to possess multipotent progenitor cell populations and has the potential to differentiate into blood cells, endothelial cells, hepatocytes, cardiomyogenic cells, smooth muscle cells, osteoblasts and so on. They can...

The plant based MYB transcription factors have been extensively studied for structural and functional characterization. protein is known to perform several molecular biological processes including regulation of gene expression. In the current study, we identified characterized a R2R3 type TF (WsMYB44) pertaining root specific library from Withania somnifera. phylogenetic studies sequence reveal...
