• self-assembly of nano-sized arjuna-bromolactone are reported. Keywords: arjunolic acid; nanochemistry; renewable; self-assembly; triterpene; Introduction Triterpenes are an important class of plant secondary metabolites derived from C30 precursors [1][2]. More than 100 triterpenoids with different

• networks [17][18]. We propose that the procedure outlined here to obtain the renewable nanosized triterpenic acids in pure form and the self-assembled fibrillar networks obtained in the aromatic solvents will find applications in various facets of supramolecular chemistry and nanoscience [19][20
