Antiproliferative Amaryllidaceae Alkaloids Isolated from the Bulbs of Sprekelia formosissima and Hymenocallis × festalis

Planta Medica, 2002
Seven alkaloids were isolated from Sprekelia formosissima, and five from Hymenocallis x festalis. Tazettine, lycorine, haemanthidine and haemanthamine were evaluated for antiproliferative and multidrug resistance (mdr) reversing activity on mouse lymphoma cells.

Cytotypes ofSprekelia formosissima(Amaryllidaceae) collected in three localities of the state of Jalisco, Mexico

The Journal of the Torrey Botanical Society, 2018
Sprekelia formosissima (L.) Herbert is a bulbous ornamental species of the Amaryllidaceae family, distributed from northern Mexico to Guatemala. Different reports on cytogenetic research on this species show differences in chromosome numbers (2n = 60, 120, 150, 180) with a basic number of x = 30. Since the chromosome number of plants can provide useful

Development of an electrochemical biosensor for phylogenetic analysis of Amaryllidaceae based on the enhanced electrochemical fingerprint recorded from plant tissue.

Biosensors & bioelectronics, 2020
A biosensor has been developed based on disposable screen-printed electrode for recording the electrochemical fingerprint of plant leaf tissue. A thin layer of polydopamine functionalized graphene sheets was coated on the plant tissue modified electrode ...
