“…The seeds are surrounded by a transparent mucilage, difficult to separate. According to Lima (2006), representatives of the Rhamnaceae family generally have ellipsoid seeds that are ovate or oblong, brown, and have a straight basal embryo and flat, membranaceous, oblong, or ellipsoid cotyledons. The seeds of Juazeiro (Zizyphus joazeiro Mart., Family -Rhamnaceae), are stenospermics, ovate or elliptic, axial embryo straight, flat and invaginated; cotyledons foliaceous with 0,5-0,8 cm long by 0,4-0,7 cm wide, beige, oblong or elliptical coloration of apex and rounded base, shaft cylindrical hypocotylradicle, small and beige coloring; inconspicuous plumule (SILVA; MATOS, 1998).…”

“…Many representatives of this family are used as ornamentals, in folk medicine, in cosmetics and in food animals, especially birds. The fruits are generally sweet and are already being inserted in the human diet in the form of jams and jellies (LIMA, 2006). Rhamnidium elaeocarpum Reissek, commonly known as "cafezinho" or "cafezinho-do-cerrado" ("little coffee" or "little coffee of the savannah"), is a South American species widely distributed in Brazil that occurs in almost all states and is found in forests, especially riparian forests (LIMA, 2011).…”

Rhamnidium elaeocarpum Reissek is a species found in forests, especially in riparian forests. This medicinal species is commonly used to reduce itching of the gums in children at the onset of teething and contains several substances responsible for antiulcer activity. The aim of the present study was to describe the external and anatomical features of the seeds, fruits, and developmental stages of seedlings of R. elaeocarpum Reissek. The processing consisted of maceration in sieves to separate the seeds from the waste. To describe the fruit, external details of the pericarp were observed and for the seeds, the external structures of the integument and internal structures of the endosperm and embryonic axis were analyzed. The morphological aspects of the seeds, germination, and seedlings of Rhamnidium elaeocarpum Reissek are homogenous in all phases. The fruit is simple, fleshy, indehiscent, and berry monospermic. The seed is exalbuminous and cream colored, with a thin and rough integument, the presence of tannin content, and an endosperm rich in starch, calcium oxalate crystals, and lipid content. Germination is hypogeal, and the seedling is cryptocotyledonary Key words: Morphological aspects, germination, post-seminal development, Rhamnaceae ResumoO Rhamnidium elaeocarpum Reissek é uma espécie encontrada em formações florestais, especialmente em matas ciliares, sendo uma planta medicinal com properiedades antiúlcerativas e utilizada para reduzir o prurido das gengivas de crianças no início da dentição e. No presente trabalho, objetivouse a descrição morfo-anatômica do fruto, da semente e das plântulas de R. elaeocarpum Reissek. O beneficiamento consistiu da maceração dos frutos em peneira, separando as sementes dos resíduos. Para a descrição dos frutos foram observados detalhes externos do pericarpo e para as sementes foram analisadas as estruturas externas do tegumento e internas do endosperma e do eixo embrionário. Os aspectos morfológicos das sementes, germinação, e plântulas de Rhamnidium elaeocarpum Reissek são homogêneas em todas as fases. O fruto é simples, carnudo, indeiscente, do tipo baga monospérmica. A semente é exalbuminosa de coloração creme, com tegumento fino. No endosperma foi detectada a presença de taninos, grânulos de amido, cristais de oxalato de cálcio, e lípidos. A germinação é hipógea criptocotiledonar. Palavras-chave: Morfologia, germinação, desenvolvimento pós-seminal, Rhamnaceae

Ampelozizyphus amazonicus is used in the treatment and prevention of malaria. The effect of an aqueous extract from this plant (SART) on the immune response was investigated by measuring immunoglobulin production induced by immunization with the antigen TNP-Ficoll in Plasmodium chabaudi-infected mice. SART treatment increased antigen-specific IgM and IgG levels in TNP-Ficoll-immunized mice. The B cell response during malarial infection was also modified by SART. There was an increase in total serum IgM and IgG and a decrease in the percentage of splenic plasma cells (CD138+ cells) in P. chabaudi-infected, SART-treated animals. SART (1, 3 or 10 mg/kg, p.o.) and the reference drug dexamethasone (5 mg/kg) were also tested in carrageenan-induced leukocyte migration to the subcutaneous air pouch (SAP). All SART doses significantly reduced leukocyte migration into the SAP. The protein concentration resulting from extravasation into the peritoneum was also significantly reduced. Our data indicate that SART possesses immunomodulatory properties, inducing an in vivo modification of the B lymphocyte response and anti-inflammatory properties, which are partly due to a reduction in cell migration and are most likely due to an inhibition of the production of inflammatory mediators. Preliminary HPLC-ESI-MS/MS analysis of SART shows a complex saponin profile with deprotonated molecule [M-H]− ions in the range of m/z 800–1000.

“…The occurrence A. amazonicus is limited to the territories of the Amazon region (Revilla, 2002). According to Lima (2006), the species has an endemic distribution in South America passing through the territories of the Brazilian, Venezuelan, Colombian and Peruvian Amazon, reaching as far as Ecuador. The plant is found in upland forests and its occurrence in Brazil is limited to the states of Amazonas, Pará and Roraima, preferably in the vicinity of streams and waterfalls (Lima, 2006).…”

A Ampelozizyphus amazonicus, conhecida popularmente como “saracura-mirá”, pertence à família das plantas Rhamnaceae. Esta planta tem ocorrência limitada à região amazônica e possui inúmeras propriedades etnobotânicas e farmacológicas. Nesta revisão, entre as propriedades farmacológicas encontradas estão as atividades antiviral, antibacteriana e antifúngica, tripanocida, antimalárica, larvicida, imunobiológica e antiinflamatória, diurética e antidiurética, citotóxica e antitumoral, adaptogênica e imunomodulatória. Não foram encontrados na literatura metabólitos relacionados à atividade antiviral, antibacteriana e antifúngica. No extrato metanólico e de etil-acetato foram encontrados os metabólitos ácido betulínico, ácido 3ß-hidroxilup-20 (29) -eno-27,28-diioico e ácido 2T, 3ß-diidroxilup-20 (29) -eno-27,28-dioico. Também não foram encontrados metabólitos para atividade antimalárica e larvicida. Saponinas complexas presentes no extrato aquoso foram relacionadas às atividades imunobiológicas e antiinflamatórias. Já as saponinas e os triterpenos misturados com saponinas do extrato etanólico de raízes secas foram relacionados a atividade diurética e antidiurética. Os compostos 3ß-hidroxilup-20(29)-en-ácido 27,28-dióico e 2T,3ß-di-hidroxilup- 20(29)-eno-27,28-ácido dióico encontrados no extrato cru de hexano, etil-acetato, etanólico, metanólico e aquoso de A. amazonicus demonstraram atividade citotóxica e antitumoral. Não foram encontrados compostos relacionados à atividade adaptogênica e imunomodulatória. O presente trabalho revisou as propriedades etnobotânicas e farmacológicas de Ampelozizyphus amazonicus.
