Clerodendrum chinense a plant native to south Asia is a perennial shrub with triangular ovate shaped
leaves. Present study involves the study of secondary metabolites and antibacterial activity of
Clerodendrum chinense. Phytochemical analysis of plant extract shows the presence of active phytoconstituents like protein, carbohydrate, sterols, alkaloids, tannins, saponins. TLC analysis revealed the
presence of β-sitosterol in the extract, which is an important phytosterol. Antibacterial activity shows
characteristic inhibition against two different strain i.e. E. coli and Pseudomonas, which suggests the
plant might show promising results in the field of antibiotics.
Clerodendrum serratum in vitro C. serratum in vitro C. serratum L. is an important medicinal plant used in Ayurveda, Siddha and Urani treatments to cure many ailments like chronic bronchial asthama, syphilis, typhoid, cancer, jaundice and hypertension. Unfortunately, due to unrestricted harvesting and less effort for its cultivation, it has been identif ied as an endangered species. The present study was aimed to develop an indirect somatic embryogenesis technique for cultivation of and to extract the pharmacologically important secondary metabolites from it. Growth regulators deprivation caused positive stimulation for somatic embryogenesis. Different stages of embryo development such as globular, heart and torpedo stage were observed in embryogenic calli. Antioxidant activity and total phenolic content were also compared between the non-embryogenic callus, different stages of embryogenic callus and wild plant. Antioxidant activity and total phenolic content were high in embryogenic callus as compared to the wild plant. This is the f irst report of regeneration of through somatic embryogenesis that can be used to produce a large numberof plants and plant products.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
