Abstract
PURPOSE OF REVIEW The Amazon region has a high biodiversity of flora, with an elevated variety of fruits, such as Camu-Camu (Myrciaria dúbia), Açaí (Euterpe oleracea Mart.), Tucumã (Astrocaryum aculeatum and Astrocaryum vulgare), Fruta-do-conde (Annona squamosa L.), Cupuaçu (Theobroma grandiflorum), Graviola (Annona muricata L.), Guarana (Paullinia cupana Kunth var. sorbilis), and Pitanga (Eugenia uniflora), among many others, that are rich in phytochemicals, minerals and vitamins with prominent antioxidant and anti-inflammatory potential. RECENT FINDINGS Studies evaluating the chemical composition of these fruits have observed a high content of nutrients and bioactive compounds. Such components are associated with significant biological effects in treating various non-communicable diseases (NCDs) and related complications. Regular intake of these fruits from Amazonas emerges as a potential therapeutic approach to preventing and treating NCDs as a nutritional strategy to reduce the incidence or mitigate common complications in these patients, which are the leading global causes of death. As studies remain largely unexplored, this narrative review discusses the possible health-beneficial effects for patients with NCDs.

Genomic decoding of Theobroma grandiflorum (cupuassu) at chromosomal scale: evolutionary insights for horticultural innovation. Gigascience 2024; 13:giae027. [PMID: 38837946 DOI: 10.1093/gigascience/giae027] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/23/2023] [Revised: 03/21/2024] [Accepted: 05/08/2024] [Indexed: 06/07/2024] Open
Abstract
BACKGROUND Theobroma grandiflorum (Malvaceae), known as cupuassu, is a tree indigenous to the Amazon basin, valued for its large fruits and seed pulp, contributing notably to the Amazonian bioeconomy. The seed pulp is utilized in desserts and beverages, and its seed butter is used in cosmetics. Here, we present the sequenced telomere-to-telomere genome of cupuassu, disclosing its genomic structure, evolutionary features, and phylogenetic relationships within the Malvaceae family. FINDINGS The cupuassu genome spans 423 Mb, encodes 31,381 genes distributed in 10 chromosomes, and exhibits approximately 65% gene synteny with the Theobroma cacao genome, reflecting a conserved evolutionary history, albeit punctuated with unique genomic variations. The main changes are pronounced by bursts of long-terminal repeat retrotransposons at postspecies divergence, retrocopied and singleton genes, and gene families displaying distinctive patterns of expansion and contraction. Furthermore, positively selected genes are evident, particularly among retained and dispersed tandem and proximal duplicated genes associated with general fruit and seed traits and defense mechanisms, supporting the hypothesis of potential episodes of subfunctionalization and neofunctionalization following duplication, as well as impact from distinct domestication process. These genomic variations may underpin the differences observed in fruit and seed morphology, ripening, and disease resistance between cupuassu and the other Malvaceae species. CONCLUSIONS The cupuassu genome offers a foundational resource for both breeding improvement and conservation biology, yielding insights into the evolution and diversity within the genus Theobroma.

Abstract
BACKGROUND Cold storage has been widely used to maintain the quality of vegetables, but whether eating cold-stored vegetables affects health remains unknown. RESULTS This study used silkworms as an animal model to evaluate the effects of nutrient changes in cold-stored mulberry leaves (CSML) on health. Compared with fresh mulberry leaves (FML), CSML contained lower vitamin C, soluble sugars and proteins, and higher H2 O2 , suggesting decreased antioxidant ability and nutrition. The CSML did not obviously affect larval survival rate, body weight or dry matter rate, cocoon shape, weight and size, or final rates of cluster and cocooning relative to the FML, suggesting CSML did not alter overall growth and development. However, the CSML increased the initial rates of cluster and cocooning and upregulated BmRpd3, suggesting CSML shortened larval lifespan and enhanced senescence. CSML upregulated BmNOX4, downregulated BmCAT, BmSOD and BmGSH-Px and increased H2 O2 in silkworms, suggesting CSML caused oxidative stress. CSML upregulated ecdysone biosynthesis and inactivation genes and elevated ecdysone concentration in silkworms, suggesting that CSML affected hormone homeostasis. CSML upregulated apoptosis-related genes, downregulated sericin and silk fibroin genes and decreased sericin content rate in silkworms, suggesting oxidative stress and protein deficiency. CONCLUSION Cold storage reduced nutrition and antioxidant capability of mulberry leaves. CSML did not influence growth and development of silkworm larva, but affected health by causing oxidative stress and reducing protein synthesis. The findings show that the ingredient changes in CSML had negative effects on health of silkworms. © 2023 Society of Chemical Industry.

Effects of Mauritia flexuosa L. f. buriti oil on symptoms induced by Bothrops moojeni snake envenomation. JOURNAL OF ETHNOPHARMACOLOGY 2023; 313:116612. [PMID: 37156448 DOI: 10.1016/j.jep.2023.116612] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 03/21/2023] [Revised: 04/27/2023] [Accepted: 05/05/2023] [Indexed: 05/10/2023]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE In Brazil, there are species of snakes that become involved in accidents and cause serious health problems to the inhabitants, highlighting the genus Bothrops for being responsible for approximately 90% of accidents reported annually. In the northern region of the country, this genus is responsible for the largest number of accidents, especially among rural dwellers. These populations invest in alternative treatments for with the purpose of improving the symptoms caused by snakebites. The species Mauritia flexuosa L. f., known as buriti, is traditionally used for the treatment of envenomation by snakes. AIM OF THE STUDY This study aimed to evaluate the antiophidic potential of the oil of Mauritia flexuosa L. f. for Bothrops moojeni H. venom, confronting cultural and scientific knowledge. MATERIALS AND METHODS The physicochemical properties were determined, and the components present in the oil, extracted from fruit pulp, were analyzed by Gas Chromatography Coupled with Mass Spectrometry. The in vitro inhibitory capacity of the oil for phospholipase, metalloprotease and serine protease activities was investigated. In the in vivo studies, male Swiss mice were used to evaluate the effect of oil on lethality and toxicity, and hemorrhagic, myotoxic and edematogenic activities were assessed. RESULTS GC‒MS analysis identification of 90.95% of the constituents of the oil, with the main components being 9-eicosenoic acid, (Z)- (34.54%), n-hexadecanoic acid (25.55%) and (E)-9-octadecenoic acid ethyl ester (12.43%). For the substrates, the outcomes indicate that the oil inhibited the activity of the main classes of toxins present in Bothrops moojeni H. venom (VBm) at the highest dose tested (0.5 μL), with inhibition of 84% for the hydrolysis of the selective substrate for serine protease and inhibition of 60% for the hydrolysis of substrates for PLA2 and metalloproteases. The antiophidic activity in vivo was evaluated with two concentrations of the oil: 1.5 mg, the dosage the population, diluted in mineral oil to a volume of 1 tablespoon and 15 mg, administered by gavage 30 min before poisoning and at time zero (concomitant to poisoning), and both concentrations administered by gavage in combination with topical use at time zero. The bleeding time in the group treated with oil at a concentration of 15 mg administered at time zero was significantly lower than that in the control group (p < 0.05). However, a greater inhibition of bleeding time was observed when local application was combined with the gavage treatment at both concentrations tested at time zero (p < 0.05). In the myotoxicity test, oil was efficient in reducing the myotoxic effects induced by the venom at the two concentrations tested, with gavage administration at time zero and gavage plus topical administration at time zero (p < 0.05). CONCLUSIONS The data obtained show that the oil is safe to use at the concentrations studied and contains fatty acids that may collaborate for cellular-level repair of the injuries caused by Bm poisoning. The in vitro and in vivo experiments showed that oil inhibits the main proteolytic enzymes present in the venom and that it has important activities to control the local effects caused by bothropic venom.

RSC Adv 2022; 12:30076-30084.

Abstract
Compound oral liquid (COL), made from functional herbal foods, has gained immense popularity in China for healthcare. However, the interaction between the nutrients in COL and gut microbiota is still unclear. In our study, the content of total flavonoids, polyphenols, and proteins was increased and the total sugar reduced by crushing raw ingredients to 10 mesh (COL-C). After 24 h incubation with supplemented COL by human gut microbiota, the results of 16S rRNA high-throughput sequencing revealed that Faecalibacterium, Collinsella, Bifidobacterium, Megamonas, Lactobacillus, Phascolarctobacterium, and Dialister were enriched by COL. In particular, the latter three genera were observed to be significantly enriched after incubation with COL-C. Meanwhile, the abundance of Dorea, Clostridium XIVa, and Escherichia/Shigella was inhibited by COL. Moreover, the increased levels of acetate, propionate, and butyrate in COL were jointly contributed by supplementary carbohydrates and the enrichment of short-chain fatty acid (SCFA)-producing bacteria. In summary, our results indicated that the optimized extraction facilitated the nutrients to be dissolved out and enhanced the potential prebiotic effects for promoting the abundance of probiotics, suggesting that the nutrients in COL-C might improve the microbial structure by strengthening the metabolism of beneficial bacteria and restricting the conditioned pathogens more efficiently. The crushing pretreatment before extraction facilitated the nutrients to dissolve in compound oral liquid and enhanced the prebiotic effects for promoting the abundance of probiotics and short-chain fatty acid synthesis.![]()

Abstract
Ficus hirta Vahl (FHV), a traditional herbal ingredient of the tonic diet, receives increasing popularity in southern China. However, it is largely unknown that how a FHV diet (FHVD) affects the human gut microbiome. In this exploratory study, a total of 43 healthy individuals were randomized into the FHVD (n = 25) and Control (n = 18) groups to receive diet intervention for 8 weeks. 16S rRNA gene sequencing, metagenomic sequencing and metabolic profile of participants were measured to assess the association between FHV diet and gut microbiome. A preservation effect of Faecalibacterium and enrichment of Dialister, Veillonella, Clostridium, and Lachnospiraceae were found during the FHVD. Accordingly, the pathway of amino acid synthesis, citrate cycle, coenzyme synthesis, and partial B vitamin synthesis were found to be more abundant in the FHVD. In addition, serine, glutamine, gamma-aminobutyric acid, tryptamine, and short-chain fatty acids (SCFAs) were higher after the FHVD. The conjoint analysis of FHV components and in-vitro fermentation confirmed that the improved SCFAs concentration was collectively contributed by the increasing abundance of key enzyme genes and available substrates. In conclusion, the muti-omics analysis showed that the FHVD optimized the structure of the gut microbial community and its metabolic profile, leading to a healthy tendency, with a small cluster of bacteria driving the variation rather than a single taxon.

Antioxidant Activity of Polyphenols, from Mauritia flexuosa (Aguaje), Based on Controlled Dehydration. Molecules 2022; 27:molecules27103065.

Abstract
Plant polyphenols offer several benefits for the prevention of diverse illnesses. Fruit’s edible and inedible parts (pulp, seeds, peels, stems, flowers) are important sources of polyphenols. Different industrial processes for fruit treatment and commercialization affect the total polyphenol content (TPC), and probably the biological activity. The purpose of the present work was to determine the TPC and antioxidant activity (by DPPH) of polyphenols extracted from the pulp and seeds of Mauritia flexuosa (aguaje), in fresh and dehydrated forms, in order to determine the possible connection with the quantity of polyphenols and their specific antioxidant activity. The highest phenolic content for M. flexuosa seeds in fresh form (non-dehydrated) was 270.75 mg GAE/100 g with a 96-h extraction. With respect to the dehydrated samples, the best yield was quantified in the 96-h dehydrated seed sample. For all pulp and seeds, dehydrated for 24, 48, and 96 h, TPC showed a slightly decreasing pattern. The DPPH results were the highest in the 96-h dehydrated samples and the differences among all dehydrated pulp and seed samples were minimal. More studies testing the presence of other antioxidant components could help in understanding the detailed antioxidant activity, and related more to the specific action, rather than only total polyphenol content.
