1.Hierarchical self-assembly of amphiphilic building blocks into various supramolecular architectures

By Shib Shankar Dash

Pages : 1-4

Molecular self-assembly is a process to obtain a well defined structure from suitable starting materials. The study of self-assembly provides a fundamental understanding of the driving forces and co-operative interaction behind these processes. In this review, the hierarchical self-assembly of amphiphilic molecules into various supramolecular architectures such as vesicles, spheres, flowers, tubes and fibrillar networks of nano- to micrometer dimensions and gels have been discussed.

2.Determination of critical vesicular concentration (cvc) of nano-sized oleanolic acid by using hydrophobic pyerene as a fluorescence probe

Previously we have reported the spontaneous self-assembly of renewable nano-sized oleanolic acid in aqueous-organic binary solvent mixtures to form vesicles (B. G. Bag and K. Paul, Asian J. Org. Chem., 2012, 1, 150 – 154). Herein, we report the critical vesicular concentration (cvc) of oleanolic acid in DMSO-Water at varied ratio. The cvc’s determined by fluorescence spectrophotometry using hydrophobic pyrene as a fluorescence probe in 2:1, 1:1 and 1:4 DMSO-water mixture were 83, 73, 47 micro

3.A review on the medicinal acivities of Andrographis paniculata

By Subrata Ghorai

Pages : 9-13

Andrographis paniculata, commonly known as Kalmegh, is one of the most popular medicinally important plants in India. The main constituents of this plant are two lactone diterpenoids namely andrographolide and deoxy-andrographolde. It is used traditionally for the treatment of several diseases such as diabetes, high blood pressure, ulcer, skin dieses, cancer and malaria since ancient times. In this review, the medicinal properties of Andrographis paniculata and its chemical constituents have be
