Antiplatelet Activity of Cucurbita maxima
Journal of Medicinal Food, 2021Natural extracts constitute an important source in the prevention of noncommunicable diseases, such as cardiovascular diseases. The pumpkin, Cucurbita maxima, is widely consumed in Chile. Pumpkin seeds, despite having crude protein, lipids, and carbohydrates, are regarded as agro-industrial waste.

Sieve-tube proteins from Cucurbita maxima
Planta, 1974The two main proteins from the phloem exudate of Cucurbita maxima Duchesne have been isolated by ammonium-sulfate precipitation, DEAE-cellulose chromatography, and gel filtration, and have been characterized. They comprise about 40% each of the total protein. The amino-acid composition of these two proteins has been determined.

Antigenotoxic spinasterol from Cucurbita maxima flowers
Mutation Research/Environmental Mutagenesis and Related Subjects, 1996The antigenotoxic constituent of squash flowers was isolated by solvent partitioning and repeated vacuum liquid chromatography. The micronucleus test, an in vivo method, was used to monitor the antigenotoxicity of the various fractions during the isolation process.

Proteins of the sieve-tube exudate of Cucurbita maxima
Planta, 1971Sieve-tube exudate which appears on cut surfaces of stems of Cucurbita maxima as distinct droplets has been depicted in electron micrographs of longitudinal sections of the phloem. The exudate, which was produced from mature sieve tubes only, contained filaments of P-protein, but no mitochondria or vesicles of endoplasmic reticulum.

Metabolic networks of Cucurbita maxima phloem
Phytochemistry, 2003Metabolomic analysis aims at a comprehensive characterization of biological samples. Yet, biologically meaningful interpretations are often limited by the poor spatial and temporal resolution of the acquired data sets. One way to remedy this is to limit the complexity of the cell types being studied. Cucurbita maxima Duch.

Synthesis of P-protein in mature phloem of Cucurbita maxima
Planta, 1976Cotyledons of Cucurbita maxima Duch. seedlings were provided with (14)C-labeled amino acids for 12 h. Besides the bulk of labeled amino acids the sieve-tube exudate also carried labeled proteins. 80% of the incorporated radioactivity was found in the P-protein, 20% in a neutral protein, and traces were found in acidic proteins after fractionation on ...

Filament formation in vitro of a sieve tube protein from Cucurbita maxima and Cucurbita pepo
Planta, 1975Phloem proteins of the sieve tube exudate from Cucurbita maxima Duch. and Cucurbita pepo L. were investigated as to their filament forming ability in vitro. From the two main proteins (116000 dalton, 30000 dalton) only the 116000 dalton protein was found to form reversibly distinct filaments of 6-7 nm diameter upon removal of SH-protecting agents from ...

Cucurbitacin 19-hydroxylase in Cucurbita maxima
Phytochemistry, 1978Abstract The enzymatic hydroxylation of the C-19-methyl group of cucurbitacin B and D was observed in partly purified preparations obtained from the unripe fruit of Cucurbita maxima . Assay methods were developed and the pH optimum, cofactor requirements, and substrate specificity determined.
