Alkaloids from Hippeastrum papilio.
Galanthamine, an acetylcholinesterase inhibitor marketed as a hydrobromide salt (Razadyne®, Reminyl®) for the treatment of Alzheimer's disease (AD), is obtained from Amaryllidaceae plants, especially those belonging to the genera Leucojum, Narcissus, Lycoris and Ungernia. The growing demand for galanthamine has prompted searches for new sources of this compound, as well as other bioactive alkal...
متن کاملIn Vitro Bulb Production in Hippeastrum (hippeastrum Hybridum)
An in vitro experiment was conducted to find out the optimum hormonal supplement and sucrose level for the bulb production of Hippeastrum. Murashige and Skoog medium supplemented with different hormone concentrations of BAP (0.0, 2.0, 4.0, 6.0 and 8.0 mg/L) and CCC (0.0, 125, 250 and 500 mg/L) and sucrose levels (30, 60, 80, 90 and 110 g/L) were used in this study. Sucrose level at 90 g/L produ...
متن کاملTwo new isoquinolone Alkaloids from Sauropus hirsutus
Sauropus androgynus (Euphorbiaceae) is a popular vegetable in Thailand. In 1995, the plant was associated with several cases of poisoning when used in a Taiwanese weight control method and the toxicity was attributed to its alkaloid content. We have therefore investigated a closely related Sauropus species, S. hirsutus. Extraction and isolation of chemical constituents from the aerial part of S...
متن کاملEnzymic and protein character of tonoplast from hippeastrum vacuoles.
The membrane of anthocyanin containing Hippeatrum petal vacuoles was examined for protein and enzyme content after purification by equilibrium density centrifugation. Light scattering, protein, and a Mg(2+)-dependent nucleotide specific ATPase were associated with membrane having a density of 1.08 to 1.12 grams per cubic centimeter. A small amount of acid phosphatase was also present in this re...
