ABSTRACT
In the present work in vitro propagation of a multipurpose medicinal plant, Withania somnifera was done. Direct
regeneration of nodal explants and their multiplication have been optimized using cytokinin BAP (0.5-5.0 mg/l) and
combination of BAP (0.5 mg/l) + IAA (1.0-3.0 mg/l) respectively. MS media with nodal explants supplemented with BAP
(2.0 mg/l) produced maximum average number of shoots (2±0.48) and average shoot length was found to be 2.8±0.26
cm. Best initiated shoots then sub cultured for shoot multiplication, an improved shoot multiplication in terms of average
number of shoots (5.3±0.41) and average shoot length 6.5±0.12 cm was observed on MS media in combination with BAP
(0.5 mg/l) + IAA (1.5 mg/l). Regenerated plantlets were successfully transferred to greenhouse condition.

INTRODUCTION
Plants in addition to their aesthetic value constitute the major natural source of the food we eat, the air
we breathe and the medicine to cure our many ills. Recently, the utilization of medicinal plants as a
natural source of drugs is being increasingly encouraged. Consequently, medicinal plants have been
targeted for uncontrolled collection and destruction as a result of urbanization, overgrazing, pollution and
expansion of cultivated areas. Plant secondary metabolism gives rise to the formation of a vast array of
chemically complex compounds, many of which are commercially important. Many problems are
associated with the production and marketing of such compounds as well as the supply of raw materials
can be erratic due to several reasons. So, it may become critical to develop an alternative source of
important therapeutically natural products. Plant cell culture provides an environmentally friendly,
renewable alternative for secondary metabolite supply [17].
Application of biotechnology for conservation of important plant species has been given priority under
circumstances, in particular when many valuable plant genetic resources are getting decimated rapidly
from natural flora [10]. Herbal medicines are still the mainstay of about 75-80% of the world population
for primary health care because of the better acceptability with the human body and less side effects [5].
Many studies revealed that cultivation of medicinal plants especially high value medicinal plants is
creating new dimension in the field of agriculture. Indian herbal industry is at blooming stage. However,
cultivation of medicinal plant is not easy. It is a challenging task because very little knowledge of seed
biology. Efforts have not been made to search elite specimen and their propagation. Withania sominifera
is a green shrub found throughout the drier parts in India, Baluchistan, Pakistan, Afghanistan, Shri Lanka,
Congo, South Africa, Egypt, Morocco, and Jordan. In India, it is widely grown in the provinces of Madhya
Pradesh, Uttar Pradesh, plains of Punjab and northwestern parts of the India like Gujarat and Rajasthan
Withania sominifera (L.)Dunal, commonly called Indian ginseng is a member of the family Solanaceae,
growing up to a height of 30-150 cm. It is considered as important medicinal plant in the Ayurvedic and
indigenous medicinal system of India. It has many medicinal properties like anti-inflammatory,
anticancer, anti-stress, anti-ageing, immune-modular, adaptogenic and shows the free radical scavenging
activity It is used for treatment of tuberculosis, rheumatism, inflammatory conditions and cardiac
diseases. It is also useful as abortificient, amoebicide, anodyne, bactericide, contraceptive and
spasmolytic. The roots are also used as sedative for senile debility and for the prevention and inhibition of
Alzheimer’s disease [20, 22, 3, 18].
