“…Plants from the Psycotrieae tribe were shown to be the major producers of alkaloids, since all phytochemical studies with genera belonging to this tribe (Camptotheca, Carapichea, Cephaelis, Chassalia, Margaritopsis, Palicourea and Psychotria) resulted in the isolation of alkaloids. In the Gardenieae tribe, the presence of iridoids was observed, not only in this survey, but also in other studies [59][60][61][62]64]. Studies showed Rubia, Galium and Morinda genera (subfamily Rubioideae) as important sources of anthraquinones, such as aglycone and rarely glycosides [56].…”

“…Furthermore, the seco-iridoids are iridoids precursors and also participate in the biosynthesis of monoterpene indole alkaloids, so they may be involved in two distinct chemotaxonomic subdivisions [57,58]. Thus, different species may exhibit different chemical substance classes, but having the same precursor, which may indicates a phylogenetic relationship [59][60][61][62][63][64]. …”

“…Soil and climatic variations such as altitude, soil type, macronutrients, micronutrients and water availability, plant age, ultraviolet radiation, rainfall, seasonality and circadian rhythm, also have great influence on the production of metabolites. Besides the fact that the chemical composition can be variable in accordance with the plant organ, it is necessary to study the plant as a whole, to be able to infer a degree of similarity [59][60][61][62][63][64].…”

Secondary Metabolites from Rubiaceae Species

This study describes some characteristics of the Rubiaceae family pertaining to the occurrence and distribution of secondary metabolites in the main genera of this family. It reports the review of phytochemical studies addressing all species of Rubiaceae, published between 1990 and 2014. Iridoids, anthraquinones, triterpenes, indole alkaloids as well as other varying alkaloid subclasses, have shown to be the most common. These compounds have been mostly isolated from the genera Uncaria, Psychotria, Hedyotis, Ophiorrhiza and Morinda. The occurrence and distribution of iridoids, alkaloids and anthraquinones point out their chemotaxonomic correlation among tribes and subfamilies. From an evolutionary point of view, Rubioideae is the most ancient subfamily, followed by Ixoroideae and finally Cinchonoideae. The chemical biosynthetic pathway, which is not so specific in Rubioideae, can explain this and large amounts of both iridoids and indole alkaloids are produced. In Ixoroideae, the most active biosysthetic pathway is the one that produces iridoids; while in Cinchonoideae, it produces indole alkaloids together with other alkaloids. The chemical biosynthetic pathway now supports this botanical conclusion.

“…The 3´,4´-dimethyl ether apometzgerin was first found as a C-glycoside in the liverwort Apometzgeria pubescens [17]. It has since been isolated from the grass Poa hueaca (Poaceae) [18], from aerial parts of Alibertia myrciifolia (Rubiaceae) [19], from leaf exudate of Nonea pulla (Boraginaceae) [14], from trapping glue of Roridula gorgonias (Roridaceae) [20], and from the exudate of aerial parts of Asarina procumbens (Scrophulariaceae) [15].…”

This paper presents a review of the occurrence of tricetin and its methyl ethers, with respect to their occurrence in the free state. In addition to literature data, our tabulated survey also includes a dozen unpublished results. The review indicates that 5,7,3´,4´,5´-pentahydroxyflavone and its methyl derivatives are more widespread than was known so far. Their presence as aglycones has been proved in a good number of plant species belonging to unrelated families.

“…Plants in the Rubiaceae family, widely distributed in the Brazilian savannah, have insecticidal properties in addition to their economic relevance. The Rubiaceae family is characterized by the presence of several classes of substances, including phenolic compounds [ 20 , 21 ]. Flavonoids and phenolic and polyphenol acids are among the most prominent [ 22 ], in addition to caffeic acids in the Alibertia genus [ 23 , 24 ].…”

Successive applications of insecticides to control Plutella xylostella L. (Lepidoptera: Plutellidae) have resulted in the emergence of resistant populations of this insect. A novel control measure for this target insect could be the use of botanical insecticides derived from plant tissues. Hence, we experimentally tested aqueous extracts of Alibertia edulis (Rich.), Alibertia intermedia (Mart.), and Alibertia sessilis (Vell.) K. Schum. found in the Brazilian savannah in order to investigate their potential to disrupt the life cycle of P. xylostella. Aqueous extracts of the leaves of A. intermedia and A. sessilis negatively affected the development of P. xylostella in all stages of the life cycle, prolonging the larval stage and causing mortality in the larval or pupal stages. Treatments with A. intermedia and A. sessilis extracts caused the lowest fecundity and the number of hatched larvae. The harmful effects of these aqueous extracts on the life cycle of P. xylostella may be attributable to the flavonoids and other phenolic compounds present in A. intermedia and A. sessilis. These aqueous botanical extracts are low in toxicity when compared to non-aqueous pesticides, and may emerge as an effective approach for control of populations of P. xylostella.
