Bio-functional constituents from the stems of Liriodendron tulipifera.
Four known compounds have been isolated from the stems of Liriodendron tulipifera, and the structures of these pure constituents were determined using spectroscopic analysis. Isolated compounds were screened for free radical scavenging ability, metal chelating power assay and ferric reducing antioxidant power assay (FRAP). The anti-tyrosinase effects of L. tulipifera compounds were calculated t...
متن کاملGrade distribution and drying degrade of sweetgum and yellow-poplar structural lumber
The fact that the supply of southern pine timber is changing to include more lower quality plantation stock may provide incentive for utilizing lower density hardwoods for structural lumber. Yellow-poplar and sweetgum are potential substitutes for southern pine. A major problem in utilizing soft hardwoods for structural lumber is the difficulties associated with drying. A study of the grade dis...
متن کاملDeep sequencing combined with microarray hybridization to identify novel and conserved microRNAs during somatic embryogenesis of hybrid yellow-poplar (Liriodendron chinense (Hemsl.) Sarg. X L. tulipifera Linn.)
Background Hybrid yellow-poplar was a man-made cross between Liriodendron tulipifera Linn.× L. chinense(Hemsl.) Sarg.. Heterosis was strong both on growth and adaptation, no matter what, the crosses or the reciprocals. During the last 12 years, somatic embryogenesis systems were successfully established in our lab, in order to meet the needs of planting materials for expanding plantations in So...
متن کاملYellow-Poplar Lumber for Exterior Architectural Applications in New Construction and for Historical Restoration
Yellow-poplar (also called tulip poplar and American tulip) has shown a resurgence in popularity in recent years due to its cost and greater abundance. Unfortunately, decay in yellow-poplar lumber can be a serious issue in just a few years (Figures 1 and 2). This publication will discuss the positive and negative attributes of yellow-poplar as an exterior millwork product and describe ongoing e...
متن کاملLiriodendron tulipifera: simulations with a spatial model of forest succession
1 Population dynamics of Liriodendron tulipifera throughout the successional sere were investigated with a spatial simulator of forest community dynamics. The simulations were complemented by data from Appalachian cove forests at different stages of development. Gap size was a key consideration in simulation of Liriodendron recruitment; seed regeneration of this shade-intolerant species was unl...
