摘 要:为研究油桦中三萜类化合物的提取工艺,以油桦树皮为原料,采用超声法提取三萜类化合物,建立油桦中三萜类化合物的高效液相色谱测定方法。应用单因素实验和响应面法考察不同超声因素对油桦中三萜类化合物总提取率的影响。最后得到的最佳条件为:超声功率380 W,提取时间42 min,提取温度63 ℃。油桦三萜类化合物的总提取率为280.72%,与理论推测值281.54%±0.55%一致。结果表明,超声法提取三萜类化合物工艺合理可靠,提取率高。

Abstract:In order to study the extraction process of triterpenoids in Betula ovalifolia, the Betula ovalifolia bark was used as raw material to extract triterpenoids by ultrasonic method, and a high performance liquid chromatography method for the determination of triterpenoids in Betula ovalifolia was established. Single factor experiment and response surface method were used to investigate the effect of different ultrasonic factors on the total extraction yield of triterpenoids in Betula ovalifolia. The best condition obtained in the end was: ultrasonic power was 380 W, extraction time was 42 min, extraction temperature was 63 ℃. The total extraction yield of triterpenoids from Betula ovalifolia was 280.72%, which was consistent with the theoretically estimated value of 281.54% ± 0.55%. The results showed that the ultrasonic extraction of triterpenoids was reasonable and reliable, and the extraction rate was high.

油桦(Betula ovalifolia)是桦木科桦木属的一种灌木,分布于中国东北部地区[1]。近年来,从天然植物中提取和分离活性物质用于临床药物的研究和开发已成为人们关注的热点。研究发现,桦树皮中含有大量的三萜类化合物,功效应用广[2-4]。其中白桦脂酸、白桦脂醇和羽扇豆醇等为桦树皮中的天然活性成分。三萜类化合物具有抗肿瘤、抗炎和抗病毒的作用。特别是针对艾滋病具有良好的生物学抗性,在药物研发中有很高的利用价值[5-8]。
目前对樺木属植物的研究主要集中在白桦树皮中三萜类化合物的提取分离、结构鉴定等方面[9-12]。……
