Brosimum alicastrum Sw, known in Mexico as the Ramón nut, is a sustainable resource in the economy of Yucatan, Mexico; the pulp and seed are edible, and the latter is very nutritious when consumed whole or ground into corn or wheat flour to make tortillas and bread. Because the inflorescences are an essential source of Moraceae taxonomic traits, th...

Mexico is a megadiverse country that has 3600 to 4000 species of medicinal plants, of which approximately 800 are used to treat conditions related to diabetes mellitus (DM). DM is a chronic degenerative disease of energy metabolism that exists as two types: type 1 (DM1) and type 2 (DM2). DM is considered a public health problem that affects 7% of t...

Seed quality and seed germination with scarification and non scarification and variable temperature and light were determined in Ch. pentadactylon seeds form two places of Guerrero and Oaxaca. Also seed viability was determined in seeds from Guerrero stored 6 months at 5º C. Seeds showed to be orthodox and dormant due to an impervious seed coat. Th...

Annonaceous acetogenins (ACGs) are molecules with carbon numbers C35–C37, usually with tetrahydrofuran and tetrahydropyran rings and one terminal γ-lactone (usually α,β-unsaturated), in a large aliphatic chain that is varyingly hydroxylated, acetoxylated or ketonized. ACGs have ecological functions as insecticides and are pharmacologically promisin...

Phyllonoma laticuspis leaves are used in Carrizal de Bravo, Guerrero, Mexico, to heal skin lesions such as injuries and smallpox sequelae and to treat diabetes mellitus type 2, and organic extracts of these leaves have been reported to exert antibacterial effects. High demand of P. laticuspis as a medicinal plant has decreased its natural populatio...

Currently, the Annonaceae family is characterised by the production of acetogenins (ACGs), and also by the biosynthesis of alkaloids, primarily benzylisoquinolines derived from tyrosine. The objective of this study was to confirm the presence of alkaloids and acetogenins in the idioblasts of the endosperm and the embryonic axis of A. macroprophylla...

Argentatin B has been shown to inhibit the growth of colon HCT-15, and prostate PC-3 cancer cells. However, the mechanism by which argentatin B inhibits cell proliferation is still unknown. We aimed to investigate the mechanism by which argentatin B inhibits cell proliferation. The cell cycle was studied by flow cytometry. Apoptosis was evaluated b...

Euphorbia dioeca Kunth belongs to the Wanderer’s herb complex that is traditionally used for skin diseases and recently as antidiabetic. The methanol and aqueous extracts were evaluated for their in vitro α-glucosidase inhibitory activity and an oral starch tolerance test. These extracts showed an IC50 of 0.55 and 0.85 mg/mL, respectively. In diabe...

Acetogenins (ACGs) are bioactive compounds with cytotoxic properties in different cell lines. They are antitumoural, antiparasitic, antimalarial, insecticidal, antimicrobial, anti-fungal and antibacterial. These secondary metabolites function in plant defence and are found in specific organelles and specific cells, thereby preventing toxicity to th...

Diuretic and antiurolithiatic activities of hexane, chloroform, methanol and aqueous extracts of Parmentiera aculeata (Kunth) Seem. (Bignoniaceae) were evaluated. The formation of bladder stones was induced surgically placing a magnesium plate in male Wistar rats (250 g). After 28 days the presence of bladder stones was corroborated by radiological...

The medicinal plant guayacan is recommended for health problems derived from diabetes mellitus. The species most often associated in the literature with the common name guayacan is Guaiacum coulteri. For this study, anatomical and histochemical comparisons were made of wood samples from five markets in Mexico City and of Guaiacum coulteri wood depo...

We describe the histopadiological changes caused by a Nacobbus aberrans population from Chapingo, Mexico on bean cultivare Negro Querétaro and Canario, which are non-hosts to this population. The plants were inoculated with 15,000 eggs and evaluated 15,45, and 90 days after inoculation (dai). For each date, the roots were embedded in Tissue Teck®O....

The effect was studied of sunlight and far-red (FR) light during seed development, on seed quality and germination of Sicyos deppei G. Don. Seeds exposed to FR during development were lighter in colour and their weight, size and water content were significantly lower. Less than 10% of non-scarified freshly harvested seeds germinated. Scarified, fre...
Article
The variation of moisture content and germinability in response to light conditions and natural dry and controlled dry conditions was studied in Sicyos deppei G. Don (Cucurbitaceae) seeds and compared with germination of seeds from green and black fruits collected directly from field plants. The increase of germi nation by scarification defines har...
Article
Sicyos deppei G. Don (Cucurbitaceae) is an annual weed that disperses dormant seeds. The influence of scarification and light on their germination was studied in the laboratory. Scarified seeds collected in 1987, 6, 7, 8, and 9 mo postharvest, gave high germination both in white light (89 to 100%) and darkness (64 to 96%), in comparison with nonsca...
