Scientific literature: Very Sparse (9 studies) · ★☆☆☆☆
Croton cajucara is a botanical species recognized for its significant medicinal potential in treating various health conditions. Research indicates that extracts from its stem and leaf, as well as preparations from its bark, exhibit notable antinociceptive and antiulcerogenic activities. These therapeutic effects are largely attributed to key chemical constituents such as trans-dehydrocrotonin, dehydrocrotonin, cajucarin A, and cajucarinolide. Studies have specifically highlighted the plant's ability to combat gastric ulcers and gastrointestinal disorders, while also demonstrating apoptotic and clastogenic properties. Consequently, this plant remains a subject of intense interest for addressing complex biological processes like apoptosis and ethanol-induced damage.

Biological Activities
Croton cajucara exhibits a diverse range of pharmacological activities that underscore its significant therapeutic potential. Research indicates that its active principle, trans-dehydrocrotonin, possesses notable antinociceptive and antiulcerogenic properties. While studies have assessed its cytotoxic effects on specific cell lines and hepatocytes, the compound often demonstrates selective behavior during metabolization. Furthermore, investigations into its safety profiles show that it does not typically display clastogenic or apoptotic activity in tested in vitro systems. Ultimately, these findings support the use of Croton cajucara derivatives as promising candidates for medicinal applications.
Compounds
Croton cajucara is a medicinal plant recognized for its diverse phytochemical profile, which includes several bioactive compounds. The stem bark of the plant serves as a rich source of clerodane-type diterpenes, specifically containing dehydrocrotonin and its isomer trans-dehydrocrotonin. In addition to these diterpenes, the plant's bark contains cajucarin A and cajucarinolide. Research into the leaves of the species has also identified the presence of the steroid beta-sitosterol. Together, these various constituents contribute to the complex pharmacological properties associated with this species.
Conditions
Croton cajucara, specifically through its active principle trans-dehydrocrotonin, demonstrates a protective effect against apoptosis induced by various mutagenic agents. The plant's components uniquely inhibit 14C-aminopyrine uptake that is otherwise induced by bethanechol. Research further indicates that its diterpenes provide significant anti-tumour activity against Ehrlich carcinoma ascitic tumours. Additionally, the plant influences cell death induction in HL60 cells, particularly when modulated by protein phosphatase inhibitors. Finally, the extracts from this medicinal plant have been shown to slightly induce NBT-reducing activity.
Preparations
Croton cajucara is prepared as bark to isolate bioactive compounds like trans-dehydrocrotonin. This specific diterpene is also obtained through the use of bark extracts from the Amazon native plant. Research indicates that these bark-derived substances possess significant anti-inflammatory and antinociceptive properties. Furthermore, the chemical constituents found within these bark extracts are studied for their potential genotoxic effects. Ultimately, the preparation of the bark serves as a vital source for investigating the medicinal qualities of the species.
Parts used
Croton cajucara is a medicinal tree from the Amazon Forest that possesses significant therapeutic potential through its various anatomical parts. The stem bark of the plant serves as a rich source of diverse clerodane-type diterpenes, including compounds like trans-dehydrocrotonin and trans-crotonin. Research indicates that these stem-derived components contribute to important pharmacological effects, such as anti-inflammatory and antinociceptive activities. Additionally, the leaves of the plant contain valuable steroids, flavonoids, and complex polysaccharides that offer gastroprotective benefits. By utilizing both the leaves and the stem, traditional medicine can effectively address a variety of health conditions.
