Variation in floral sex allocation in Polygonatum odoratum (Liliaceae).
BACKGROUND AND AIMS It is well known that resource allocation to male and female functions can be highly variable in hermaphroditic plants. The purpose of this study was to investigate variations in sexual investment at different levels (flower, plant and population) in Polygonatum odoratum, a plant with sequentially opening flowers. METHODS Pollen and ovule production in base, middle and top...
متن کاملSteroidal Saponins from the Roots and Rhizomes of Tupistra chinensis.
Two new furostanol saponins 1-2 and a new spirostanol saponin 3 were isolated together with two known furostanol saponins 4-5 from the roots and rhizomes of Tupistra chinensis. Their structures were characterized as 1β,2β,3β,4β,5β,26-hexahydroxyfurost-20(22), 25(27)-dien-5,26-O-β-d-glucopyranoside (1), 1β,2β,3β,4β,5β,6β,7α,23ξ,26-nona-hydroxyfurost- 20(22),25(27)-dien-26-O-β-d-glucopyranoside (...

Eleven new furostanol saponins, typaspidosides B-L (1-11), one new spirostanol saponin, typaspidoside M (12), and five known spirostanol saponins, 25S-atropuroside (13), neoaspidistrin (14), (25S)-pratioside D1 (15), 25S-aspidistrin (16) and 25S-neosibiricoside (17) were isolated from the rhizomes of Aspidistra typica Baill. The structures of the new compounds were established using 1D and 2D N...
متن کاملSteroidal Saponins from the Rhizomes of Anemarrhena asphodeloides.
Four new steroid saponins 1-4 were isolated from the rhizomes of Anemarrhena asphodeloides (Asparagaceae), as well as four known saponins: anemarsaponin B (5) timosaponin D (6), timosaponin E1 (7) anemarsaponin B II (8). Their structures were established through UV and NMR as well as MS data. All the compounds were evaluated for cytotoxicity against HepG2 and SGC7901 human cancer lines. Compoun...
