Abstract

Sea buckthorn (Hippophae rhamnoides L.) twigs, remaining after harvesting and pruning, are an underutilized and little-explored biomass resource. This study investigated the content of serotonin in 10 sea buckthorn cultivars (‘Maria Bruvele’, ‘Botanicheskaya Lubitelskaya’, ‘Tatiana’, ‘Otto’, ‘Leikora’, ‘Duet’, ‘Clara’, ‘Lord’, ‘Eva’, ‘Tarmo’) for the first time, and for further adjustment of the extraction conditions, cultivar ‘Maria Bruvele’ was extracted by water and water/ethanol solution with 20-25, 50, 70, and 96% ethanol at different temperatures. The results showed that 50% water/ethanol solutions are the most suitable for extraction, which makes it possible to increase the yield of serotonin. The 2-year-old twigs and bark from ‘Maria Bruvele’ collected in autumn contained higher serotonin content compared to spring-collected biomass. Serotonin sequential purification allowed the serotonin content in the fraction to increase to 26%/DM. The serotonin-rich fraction showed antimicrobial activity against gram-positive and gram-negative bacteria. In tests with salivary amylase, a serotonin-rich fraction at the amount of 0.1-0.4 mg/mL of saliva, under normal physiological conditions, tended to increase amylase activity, resulting in acceleration of starch degradation to glucose. Thus, the results support further study of the serotonin fraction for the treatment of people having underweight, malnutrition, and malabsorption conditions.

沙棘（Hippophae rhamnoides L.）修剪废料作为潜在血清素来源的比较评估

沙棘（Hippophae rhamnoides L.）树枝是一种收获和修剪后剩余的生物质资源，但未得到充分利用，也鲜有开发。本研究调查了 10 个沙棘栽培品种（'Maria Bruvele'、'Botanicheskaya Lubitelskaya'、'Tatiana'、'Otto'、'Leikora'、'Duet'、'Clara'、'Lord'、'Eva'）中血清素的含量、为了进一步调整萃取条件，栽培品种'Maria Bruvele'首次在不同温度下用水溶液和含 20%-25%、50%、70% 和 96%乙醇的水/乙醇溶液进行萃取。结果表明，50%的水/乙醇溶液最适合萃取，可以提高血清素的产量。与春季采集的生物质相比，秋季采集的'Maria Bruvele'2年树龄的树枝和树皮含有更高的羟色胺含量。血清素的连续纯化使馏分中的血清素含量增加到 26%/DM。富含血清素的馏分对革兰氏阳性和革兰氏阴性细菌具有抗菌活性。在唾液淀粉酶测试中，在正常生理条件下，唾液中含量为 0.1-0.4 毫克/毫升的富含血清素的馏分往往会增加淀粉酶的活性，从而加速淀粉降解为葡萄糖。因此，研究结果支持进一步研究血清素组分对体重不足、营养不良和吸收不良患者的治疗作用。
