As an example, suppose that it is known to experts in the field that an extract from the plant Clusia criuva has anti-inflammatory activity. Therefore, a specialist in the subject would be led to test other species of the genus Clusia for the same biological activity (anti-inflammatory). Nevertheless, a way to prove inventive step would be to demonstrate that the species of interest, for example Clusia rosea, presents an unexpected technical effect. In other words, while the species Clusia criuva has an undesirable side effect associated with its anti-inflammatory action, such... 

Propolone A (72) was isolated in large quantities from an ethanol extract of Cuban propolis [11]. This finding and the isolation of nemorosone from C. rosea has permitted to suggest the role of this plant in the chemical composition of Cuban propolis. However, propolone A has not been reported as a component of Clusia rosea s floral resin, the main Clusia sp. distributed in Cuba. Thus, propolone A can be a derivative of nemorosone and the conversion would occur whereas the process of conservation and treatment of propolis samples and extracts are carried out. Some authors have reported that natural PBDs are unstable mainly in solutions and our experiences are in agreement with those observations. On the other hand, Porto et al. noted the structural similarities between the PBD isolated from floral resins of C. scrobiculata scrobiculatone A (63) [20] and propolone A. However, the first one has not been isolated from floral resins of C. rosea so far.
