  Conventional propagation methods take a long time for multiplication because of low rate of growth set or poor germination of the seeds but tissue culture has an important role to play in the manipulation of plants for improved agronomic performance using different concentrations and combinations of plant growth regulator. Murashige and Skoog (MS) media with different combinations and concentrations of growth promoters i.e., auxin (Indole Acetic Acid (IAA), Indole Butyric Acid (IBA)), +synthetic auxin 2, 4-D (2, 4 dichlorophenoxy acetic acid), cytokinin (Benzyl Amino Purine (BAP), +synthetic cytokinin (kinetin (KN) and gibberellin (Gibberalic Acid (GA3). The efficient development of callus type was observed in the MS media supplemented with NAA (2 mg L–1) +kin (2 mg L–1). Three different types of explants viz., leaf (Petiole, middle and tip regions), shoot tips, root and petioles were cultured on MS medium containing 2,4 D, NAA, kinetin and their combinations. Callus was induced from petiole of the leaves of the Aquilegia nivalis. Highest and earliest callus formation (29 days) were observed on MS medium containing NAA (1.5 mg L–1) +kinetin (1 mg L–1). Callus proliferation was observed on 2, 4D (2 mg L–1) +kinetin (2 mg L–1) containing medium. Callus induction was not influenced by the season of the explant condition.

  Background and Objectives: Platanus orientalis also called Oriental plane or Chinar or Boonyi (Platanaceae) is a large, deciduous tree, known for its longevity and spreading crown. The present work describes determination of antioxidant, anti-inflammatory and total phenol content of Platanus orientalis. Materials and Methods: Different extracts of the plant such as stem, root and leaves were prepared in different solvents such as chloroform, methanol and water. Results: Total phenol content in this plant reveal that methanol extract of Platanus orientalis root showed maximum free radical scavenging activity followed by methanol wood extract. Antioxidant activity of the plant extracts in this study reveal that it is methanol and chloroform extracts which showed above 50% inhibition in contrast to aqueous extracts. Anti-inflammatory activity of Platanus orientalis showed that aqueous wood extract of Platanus orientalis showed maximum activity in contrast to other extracts. With the help of acute toxicity test it was found that all the extracts are nontoxic at 2 g kg –1 b.wt. to Wistar rats. Conclusion: These finding provides some biological value of different extracts of Platanus orientalis for the use as antioxidant and anti-inflammatory agents. However, further investigation on isolation and purification of the bio-active molecules is needed to explore the exact mechanism of action of the Platanus orientalis extracts.
