“…The extraction was performed by the acid-base method. [22,36] The extracts were stored in a dark environment until the total alkaloids were quantified in a spectrophotometer with absorbance at 254 nm, according to Sousa et al [ 37] Liriodenine was also individually quantified with the aid of a High-Performance Liquid Chromatography (UHPLC Focused Thermo Fisher-Scientific), as it is considered a chemophenetic marker of the family, as well as a compound capable of obtaining the number of substances in the alkaloids profile. For the High-Performance Liquid Chromatography analysis, a gradient pump and UVVIS detector were used with a C18 reverse-phase column (150 × 4.6 mm and 5 μm particle diameter).…”

Annona emarginata (Annonaceae) has two morphological variations (A. emarginata ‘mirim’ and A. emarginata ‘terra‐fria’). The species has agricultural value and produces specialized metabolites of pharmacological interest. The objective of this work was to analyze whether chemical and morphological differences contribute to differentiate A. emarginata ‘terra‐fria’ from A. emarginata ‘mirim’, as chemophenetic variations of A. emarginata. The analysis of chemical compounds was based on the quantification, profile of root alkaloids and on the leaves volatile profile, together with morphometric analyses of the leaf blade. The samples were collected in three phenological stages (flowering, fruiting, and vegetative) at two places in São Paulo, Brazil. Differences in the composition of the alkaloid profile and leaf volatiles (in both places and in the three phenological stages) allowed us to separate the two morphotypes by multivariate statistical analysis. These differences agreed with the leaf blade morphology and flower color. This first chemophenetic report of A. emarginata demonstrates that, in addition to morphological variations, the specialized metabolism of roots and leaves can be phytochemical characters, which suggest the existence of at least morphochemotypes of A. emarginata.

“…Liriodenine, an alkaloid found in abundance in the Annonaceae family [20,[24][25][26][27], has several potent biological activities [28,29], including potential antibacterial [24], antiprotozoal [30,31], cytotoxic [32,33] and antifungal activities [34]. In particular, it has activity against more than 20 phytopathogens, including Rhizopus stolonifer and Aspergillus glaucus, fungi that impair seed germination [25].…”

The Brazilian Cerrado is the second largest Brazilian biome. In recent decades, a reduction in rainfall has indicated an extension of the dry season. Among the many native species of the Cerrado of the Annonaceae family and used in folk medicine, Annona crassiflora Mart. has fruits of high nutritional value and its by-products are sources of bioactive compounds, such as alkaloids. The aim of the study was to investigate how water stress impacts the production of alkaloids. The study was carried out in a nursery, and the knowledge was flood, field capacity and drought. Gas exchange, chlorophyll a fluorescence, antioxidant enzymes, total soluble sugars, starch, reducing sugars, sucrose, total alkaloids and liriodenine were analyzed. We observed that plants subjected to drought had an increase in the production of total alkaloids and liriodenine, without a reduction in photosynthetic metabolism. Plants kept under drought and flood conditions dissipated higher peroxidase activity, while catalase was higher in flooded plants. Starch showed the highest concentration in flooding plants without differing from drought plants; the lowest trehalose concentrations were found in both drought and flooding plants. The drought stimulated the synthesis of total alkaloids and liriodenine without reducing the primary metabolism, which suggests adaptation to Cerrado conditions.
