Abstract

Abstract We investigated the distribution of extractive, phenolic, and polysaccharides content of young S. mahagoni trees aged 1 to 5 years. The wood powder materials in two vertical positions (bottom and top) were successively extracted using n-hexane, methanol, and hot water solutions. The results showed that there was a significant interaction between the tree age and axial position in all parameters. The methanol and total extractive content decreased significantly from 1 to 3-year-old at the top part. In contrast, the amount of hot water and total extractive increased significantly from 3 to 4-year-old trees at the bottom part. Furthermore, a significant increase was also found at the bottom heartwood for hexane, methanol, and the total extractive from 4 to 5-year-old trees. The reverse trend was observed in the polar fractions (methanol and hot water) at the top of the trees. Generally, the extractive pattern tends to decrease from bottom to top with the highest proportion of methanol extract (70% based on the total extractive weight), and it increased from sapwood to heartwood. The total phenolic content (TPC) and total soluble polysaccharides (TSP) generally increase with tree age (except for TSP from 2 to 3-year-old trees at the top part). The high content of TPC in the heartwood and TSP in the sapwood indicated the process of heartwood formation. In addition, a drastic decrease in the methanol extract and TSP at the age of 3 years at the top indicated that the TSP was transferred from top to bottom for the heartwood formation at the bottom part of 4-year-old trees.
马氏甜草苗提取物含量的变化心材形成期间的杰克树
摘要研究了1 ~ 5年树龄mahagoni幼树的提取物、酚类和多糖含量的分布。分别用正己烷、甲醇和热水溶液对竖直位置(底部和顶部)的木粉材料进行萃取。结果表明,各参数中树龄与轴位之间存在显著的交互作用。顶部1 ~ 3年甲醇和总浸出物含量显著下降。而底部3 ~ 4年生树木的热水用量和总浸出物量均显著增加。此外,4 ~ 5年树龄的底层心材中己烷、甲醇和总提取物的含量也显著增加。在树顶的极性馏分(甲醇和热水)中观察到相反的趋势。从总体上看,提取方式自下而上呈递减趋势,甲醇提取比例最高(占总提取重量的70%),从边材到心材呈递增趋势。总酚含量(TPC)和总可溶性多糖(TSP)一般随树龄增加而增加(顶部2 ~ 3年树龄的TSP除外)。心材中高含量的TPC和边材中高含量的TSP表明了心材的形成过程。此外,3年树龄时顶端甲醇提取物和总皂苷含量急剧下降,说明4年树龄下部心材形成过程中总皂苷由上向下转移。
