Phenolic, fatty acid, and phytosterol contents in sweet potato (SP) fermented by Lactobacillus acidophilus were evaluated and compared with those of raw and boiled SPs. The differences in the profiles and levels of phenolics between the raw and boiled SPs were not as significant as the differences
The present study provides the method for simultaneous separation and determination of concentration and evaluates anti-breast cancer activity of three phytosterols from the sweet potato (Ipomoea batatas L.): daucosterol linolenate (DLA), daucosterol linoleate (DL), and daucosterol palmitate (DP). A
Breast cancer (BC) is a prominent source of cancer mortality in women throughout the world. β-Sitosterol-d-glucoside (β-SDG), a newly isolated phytosterol from sweet potato, possibly displays potent anticancer activity. However, the probable anticancer mechanisms involved are still unclear. This
Diabetes mellitus has been recognized as a clinical syndrome since ancient times, and remains a crippling global health problem today. It is a group of heterogeneous, autoimmune, hormonal and metabolic disorders, often accompanied by hypertension, hyperlipidemia and obesity. Current estimates
Potato tuber is a highly nutritious, wherein genotype and environmental differences are known to exist in the shape, size and nutritional value of potatoes. Owing to its high consumption, potato could be an ideal carrier of health-promoting phytochemicals. Potato cultivars contain many bioactive

Phytosterol homeostasis may be maintained in leaves through diversion of intermediates into glycoalkaloid biosynthesis, whereas in tuber flesh, excess intermediates are catalyzed by tuber-specific StLAS - like , resulting in low tuber glycoalkaloids. Lanosterol synthase (LAS) and
Lipophilic bioactive compounds and hydrophilic primary metabolites from potato (solanum tubersum L.) tubers with different-colored flesh (white-, yellow-, red-, and purple) were characterized. The carotenoid content was relatively higher in red-colored potatoes, in which lutein was most plentiful.
When free phytosterols are adequately heated and then cooled in fat, they recrystallize and are rendered bioavailable for blocking cholesterol absorption. To extend the application of phytosterols to fried foods, the activity of these modified crystals was assessed in 2 experiments with 26 male
Late blight of potato (Solanum tuberosum L.) caused by the oomycete Phytophthora infestans (Mont.) de Bary, is one of the most important bottlenecks of potato production worldwide. Cultivars with high levels of durable, race unspecific, quantitative resistance are part of a solution to this problem.
Geographically the prevalence of duodenal ulceration is related to the staple foods in the diet in regions of developing countries where the diet is stable. It is higher in regions where the diet is based on milled rice, refined wheat or maize, yams, cassava, sweet potato, or green bananas, and is
1. The mechanism of cycloartenol biosynthesis in leaves of Solanum tuberosum was investigated with the use of [2-(14)C,(4R)-4-(3)H(1)]mevalonic acid. 2. The (3)H/(14)C atomic ratio in cycloartenol was 6:6, the same as that in squalene; this eliminates lanosterol as a possible biosynthetic precursor
A large part of chemodiversity of plant triterpenes is due to the modification of their side chains. Reduction or isomerization of double bonds in the side chains is often an important step for the diversification of triterpenes, although the enzymes involved are not fully understood. Withanolides
Steryl glycosides (SG) contribute significantly to the total intake of phytosterols. The standard analytical procedure involving acid hydrolysis fails to reflect the correct sterol profile of SG due to isomerization of some of the labile sterols. Therefore, various glycosylases were evaluated for
The lipophilic extracts from the storage root of 13 cultivars of sweet potato (Ipomoea batatas (L.) Lam.) were evaluated by gas chromatography-mass spectrometry with the aim to valorize them and offer information on their nutritional properties and potential health benefits. The amount of lipophilic
