为探讨大豆低聚肽(SOP)和大豆低聚糖(SOS)复合物对家蚕寿命的影响,把同一批二龄蚕随机分为4组(对照组、低剂量组、中剂量组、高剂量组),将不同浓度的SOP和SOS复合物溶液(复配比为SOP∶SOS=65∶35)涂于桑叶上连续喂养至结茧,观察家蚕生长情况并计算幼虫期和成虫期的平均寿命和最长寿命及对应的延长率。结果表明:SOP和SOS复合物高剂量组(20%)家蚕在幼虫期内平均寿命和最长寿命延长率可达12.69%和14.29%;在成虫期内平均寿命和最长寿命延长率为15.5%和18.37%,有明显的延缓衰老作用,复合物溶液在2.5%~20%范围内,随剂量的增加,延缓衰老作用增强。
In order to investigate the effect of soybean oligopeptide (SOP) and soybean oligosaccharide (SOS) on the life span of silkworm, the same group of second instar silkworm was randomly divided into 4 groups (control group, low dose group, middle dose group, high dose Group), different concentrations of SOP and SOS complex solution (compound ratio SOP: SOS = 65:35) were applied to the mulberry leaf continuously cocoon, observed the growth of silkworm and calculated larvae and adult period average Longevity and longest life expectancy and the corresponding extension rate. The results showed that the average life expectancy and the longest life expectancy of the high-dose SOP and SOS complex (20%) silkworms increased by 12.69% and 14.29%, respectively. The average life expectancy and the longest life expectancy in adult larvae were 15.5 % And 18.37%, respectively. The anti-aging effect was obvious. The complex solution was in the range of 2.5% -20%. With the increase of dosage, the anti-aging effect was enhanced.
