Mucoadhesive polymers that bind to the gastric mucin or epithelial cell surface are useful in drug delivery for the purpose of increasing the intimacy and duration of contact of drug with the absorbing membrane. Several synthetic polymers are in use for this purpose. Since the biodegradability of the synthetic polymers are questionable, in this investigation, an oral mucoadhesive controll...

VP24, an abundant protein of 24 kD, was found to accumulate in the anthocyanin-containing vacuoles of cells of sweet potato (Ipomoea batatas) in suspension culture. Light-induced expression of VP24 was analyzed by immunoblotting in three different cell lines that produced anthocyanins at different rates. The expression of VP24 was closely correlated with the accumulation of anthocyanin in these...

In this study, we collected life table data for the sweetpotato weevil, Cylas formicarius, grown on Ipomoea batatas and Ipomoea triloba, and analyzed them using an age-stage, two-sex life table. We also demonstrated the growth potential of C. formicarius on these two host plants by using population projection. These data will be useful to the growers to the selection or eradication of host plan...

Molecular markers are needed for enhancing the development of elite sweetpotato (Ipomoea batatas (L.) Lam) cultivars with a wide range of commercially important traits in sub-Saharan Africa. This study was conducted to estimate the heritability and determine trait correlations of storage root yield, dry matter, starch and β-carotene content in a cross between 'New Kawogo' × 'Beauregard'. The st...

Although Japanese morning glory (Ipomoea nil (L.) Roth.) has been used intensively for genetic studies, DNA markers have not been developed in Ipomoea nil sufficient to cover all chromosomes. Therefore, we conducted microsatellite (simple sequence repeats, SSR) marker development in I. nil for future genetic studies. From 92,662 expressed sequence tag (EST) sequences, 514 unique microsatellite-...

Ziziphus mauritiana is a plant species belonging to the Rhamnaceae family. It commonly found in tropical and subtropical regions of Asia, Indonesia, this grows wild thrives on islands Bali, Lombok Sumbawa. The fruits Z. are edible, however, it underutilized has very low economic value. To evaluate its possibility be developed as functional food, study was conducted determine total phenolics fla...

Stem bark of Acacia nilotica, Delbergia sissoo, Delonix regia, Polyalthia longifolia, Prosopis cineraria, and Zyziphus mauritiana, and leaves of Catharanthus roseus, Mentha arvensis, Murraya koinigii, Ocimum basilicum, Tabernaemontana divaricata, Tinospora cordifolia and Tribulus terrestris were analyzed for their total phenolic and flavonois content as well as antioxidant activity. Stem bark o...
