Sayote is a tropical perennial vine, with stems climbing to 40 feet high. Rootstock is tuberous. Leaf petioles are 6 inches long. Leaves
are hairy, broadly cordate, entire or angled, 10 to 20 centimeters long. Flowers are staminate, yellowish to pale green, in long racemes. Pistillate flowers are solitary, corolla 12 to 17 millimeters. Fruit is pear-shaped, light green, and slightly wrinkled or with shallow, narrow, longitudinal grooves, in some forms set with soft spines. Seed is single, large, with a smooth testa, clinging to the flesh, protruding from the fruit apex.
Probably native to Mexico.
- Study yielded eight flavonoids
including three C-glycosyl and five O-glycosyl flavones. The leaves
gave the highest amount of flavonoids
Leaves and fruit.
- The fruit, tuber, stems and leaves are edible.
- Leaves are used in stews.
- Low in fiber, high in carbohydrate and caloric content.
- Fruit is laxative.
- Raw pulp of the fruit is soothing for skin rashes.
- Roasted leaves help in the suppuration of boils.
Leaf ethanolic extracts and leaf and seed water extracts showed strong
inhibitory activity by B-carotene bleaching. Results may be potentially
exploited as biopreservatives and for health supplements or food to
alleviate oxidative stress.
Extract studies produced a fall in blood pressure. The mechanisms
were not determined in the preliminary experiments. Further studies are indicated to delineate the mechanims involved in decreased mean arterial pressure.
Phytochemical study yielded eight flavonoids, including three C-glycosyl and five o-glycosyl flavones. Results showed the highest amount of flavonoids was in the leaves, followed by roots and by stems.
Alcoholic extracts of Sechium edule were tested against bacteria of clinical relevance as nosocomial pathogens. Results showed both fluid extract and tincture have very good antimicrobial efficacy against all strains of multiresistant staphylococci and enterococci and warrants further studies to isolate and identify the active principle/s.
• Radiopharmaceutical Labeling and Uptake Effect:
The Effect of a Chayotte (Sechium edule) Extracts (Decoct and Macerated) on the Labeling of Blood Elements with Technetium- 9m and on the Biodistribution of the Radiopharmaceutical Sodium Pertechnetate in Mice: an In vitro and In vivo Analysis. The study suggests that some component of chayote extracts present an oxidant power to alter the biodistribution of Technitium-9m and cause alteration of the uptake in organs.
Treatment with an ethanolic extract of fruit significantly protected against aspirin-induced ulceration with reduction of total acidity, free acidity, gastric output and increase pH of gastric secretion.
Study yielded eight flavonoids, including three C-glycosyl and five o-glycosyl flavones. Aglycone moieties are represented by apigenin and luteolin; the sugar units by glucose, apiose and rhamnose.
