Abstract

The content and composition of extractives in the wood and bark tissue of black locust (Robinia pseudoacacia L.) were investigated. Wood and bark samples were extracted using a Soxhlet apparatus with acetone. The extracts were gravimetrically examined to measure total hydrophilic extractive content. Total phenolic content was measured colorimetrically with a UV-Vis spectrophotometer. The wood and bark extracts were further investigated using high-pressure liquid chromatography (HPLC) to identify and quantify dihydrorobinetin in the extracts. The contents of total hydrophilic extractives, total phenols and dihydrorobinetin were higher in heartwood than in the sapwood and bark. No relationship was found between the height at which the samples were taken from the stem and the content of soluble components in the wood and bark. The heartwood of black locust represents a rich potential source of phenolic extractives.

黑莓(Robinia pseudoacia L.)树皮和木材中提取物的含量
对刺槐(Robinia pseudoacacia L.)木材和树皮组织中提取物的含量和组成进行了研究。木材和树皮样品用丙酮索氏装置提取。用重量法测定提取物的总亲水提取物含量。用紫外-可见分光光度计比色法测定总酚含量。采用高压液相色谱法(HPLC)对木材和树皮提取物进行了进一步的研究,并对提取物中的二氢比宾素进行了鉴定和定量。心材中总亲水浸出物、总酚和二氢连翘素含量高于边材和树皮。没有发现从茎中提取样品的高度与木材和树皮中可溶性成分的含量之间的关系。刺槐的心材具有丰富的酚类提取物的潜在来源。
