Abstract:In this study, acid and neutral fractions and three diterpenes were isolated from the hexane extracts from roots of three individual specimens of Croton blanchetianus Baill., collected from the same geographical site. Moreover, the antimicrobial activity of the extracts, fractions and diterpenes isolated was evaluated against Streptococcus mutans and Streptococcus parasanguinis, bacteria related with dental caries. The structures of the diterpenes were elucidated mainly by 1D and 2D nuclear magnetic resonance … Show more
“…The medicinal category recorded for P. pyramidalis and C. blanchetianus has been seen as significant potential use. Recent studies on the use of chemical extracts from these two species were published by Firmino et al (2018Firmino et al ( , 2019, respectively (Firmino et al, 2018(Firmino et al, , 2019. Their results indicate potential uses that can contribute to the development of conservation measures for such species, mainly because of the low damage caused by the extraction of leaves or bark, which are the main plant parts used for medicinal purposes.…”
The climate change expected for the coming decades it is expected an increase in the number of semi-arid regions worldwide and the frequency of climatic extremes. When climatic changes such as those expected for semi-arid regions occur in a conflict environment with no resilience structure, they can influence how factors that affect the environmental structure may also affect the social structure. To identify how the traditional use of native plant species can be influenced by a change in their availability in a certain area, 26 residents in the semi-arid region, were interviewed. Then, a Use Preference Pressure Index (UPPI) was applied to identify the most used species in the rural community of Santa Rita, located in the semi-arid region of Paraíba, Brazil. Sixteen species, classified into nine categories of use, were identified. The species with the highest use preference were sampling through damage analysis, identifying the types of extraction related to the categories used to determine the most worrying issues. The used species also had high potential for other medicinal purposes. The current uses recorded in Santa Rita showed a high potential for adaptation to landscape changes toward the reduction of vegetation loss impacts, as a response to climatic variability.
