“…Aleurites moluccana (L.) Willd., belonging to the Euphorbiaceae family, is commonly known as “Candlenut tree” or “Indian walnut.” Widely distributed in the south and southeast of Brazil, the leaves are used in folk medicine to treat fever, inflammation, asthma, hepatitis, headache, gastric ulcer, and other ailments. Its seeds are used as an antirheumatic and as a fertilizer [ 2 , 3 ].…”

The aim of the study was to analyze the constituents of the dichloromethane fraction obtained from A. moluccana and also to evaluate the anti-inflammatory and antinociceptive properties of α,β-amyrenone isolated from A. moluccana in mice. The dichloromethane fraction was evaluated by gas chromatography and submitted to purification. The mixture of α,β-amyrenone was isolated and then evaluated using the carrageenan-induced paw-oedema or pleurisy and CFA-induced arthritis models in mice. Five triterpenes, α,β-amyrenone, glutinol, and α,β-amyrin were isolated from dichloromethane fraction of A. moluccana leaf extract. The mixture of α,β-amyrenone, dosed orally, was able to reduce mechanical hypersensitivity and paw-oedema induced by carrageenan, interfering with neutrophil migration. Similar results were observed in the carrageenan-induced pleurisy model. Repeated administration of the compounds was also effective in reducing the mechanical sensitization and oedema developed in the arthritis model induced by CFA. In conclusion, the results demonstrate that α,β-amyrenone interferes in both acute and chronic inflammatory processes. We can infer that these effects involve, at least in part, a reduction in the neutrophil migration. Therefore, it seems reasonable to suggest that α,β-amyrenone could represent a new therapeutic tool for the management of painful and inflammatory diseases, especially those presenting a chronic profile.

The HPLC-UV method previously developed for the analysis of the flavonoid 2"-O-rhamnosylswertisin (I), an active compound of dried leaf extracts of Aleurites moluccana L. Willd, was fully validated with the inclusion of another flavonoid, swertisin (II). The stability-indicating capability of the method was established by analyzing forced degradation extract samples (acid, alkali, neutral, oxidative and photolytic condition) in which the spectral purity of the markers was ascertained together with the separation of degradation products from the markers. The method proved be linear over a range of 5.89-117.8 and 1.38-27.68 g.mL -1 for I and II, respectively. The recovery for I and II was 100.3 and 102.8%, respectively, at a level of 100%. A relative standard deviation (RSD%) < 1.0% (intra-day) and < 3.5% (inter-days) for area, and less than 0.5% for retention time indicated that the precision of the method is acceptable. Validation parameters such as selectivity and robustness were also determined. In addition, during the course of LC-MS n analysis three other flavonoids were discovered in the A. moluccana extract and their tentative structures identified.

“…The Euphorbiaceae family is important because several of its members are cultivated for food, medicine, production of poisons, oils and fats, waxes, gums, rubber, components for paints, varnishes, and as ornamentals. It is estimated that in Mexico this family is represented by 43 genera and 782 species, of which the largest genera are: Euphorbia (241 spp., 31%), Croton (124 spp., 16%), Acalypha (108 spp., 14%), Jatropha (48 spp., 6%) and Phyllanthus (41 spp., 5%) ( Pascual and Correal, 1992 ; Steinmann, 2002 ).…”

The range of floral colors is determined by the type of plant pigment accumulated by the plant. Anthocyanins are the most common flavonoid pigments in angiosperms; they provide a wide range of visible colors from red-magenta to blue-purple, products of cyanidin and delphinidin biosynthesis, respectively. For the floriculture industry, floral color is one of the most important ornamental characteristics for the development of new commercial varieties; however, most plant species are restricted to a certain color spectrum, limited by their own genetics. In fact, many ornamental crops lack bluish varieties due to the lack of activity of essential biosynthetic enzymes for the accumulation of delphinidin. An example is the poinsettia (Euphorbia pulcherrima Willd. ex Klotzsch), the ornamental plant symbol of Christmas and native to Mexico. Its popularity is the result of the variety of colors displayed by its bracts, a kind of modified leaves that accumulate reddish pigments based mainly on cyanidin and, to a lesser extent, on pelargonidin. The commercial success of this plant lies in the development of new varieties and, although consumers like the typical red color, they are also looking for poinsettias with new and innovative colors. Previous research has demonstrated the possibility of manipulating flower color through metabolic engineering of the anthocyanin biosynthesis pathway and plant tissue culture in different ornamental plant species. For example, transgenic cultivars of flowers such as roses, carnations or chrysanthemums owe their attractive bluish colors to a high and exclusive accumulation of delphinidin. Here, we discuss the possibilities of genetic engineering of the anthocyanin biosynthetic pathway in E. pulcherrima through the introduction of one or more foreign delphinidin biosynthetic genes under the transcriptional control of a pathway-specific promoter, and the genome editing possibilities as an alternative tool to modify the color of the bracts. In addition, some other approaches such as the appropriate selection of the cultivars that presented the most suitable intracellular conditions to accumulate delphinidin, as well as the incorporation of genes encoding anthocyanin-modifying enzymes or transcription factors to favor the bluish pigmentation of the flowers are also revised.
