植物提取物在家畜精液冷冻保存中的研究与应用进展

Study and Application of Plant Extracts in Cryopreservation of Animal Semen

植物提取物是从植物中提取的天然抗氧化剂,其在精液冷冻保存过程中能清除多余的活性氧,降低精子的氧化损伤,减少丙二醛产生,提高精子活力与精子各项运动参数,从而提高解冻后的精液品质。本文综述了近几年植物提取物(迷迭香提取物、茶多酚、红景天多糖、葡萄籽原花青素、竹叶黄酮、白藜芦醇、番茄红素和槲皮素)在家畜精液冷冻保存上的应用与研究,旨在为进一步深入研究家畜精子氧化损伤机制提供理论依据。

Plant extracts are natural antioxidants extracted from plants.In the process of semen cryopreservation,it can remove excess reactive oxygen species,reduce the oxidative damage of the sperm,reduce the production of the malondialdehyde,improve sperm motility and various motion parameters,so as to improve the quality of thawed semen.In this paper,the application and research of plant extracts(rosemary extract,tea polyphenol,rhodiola polysaccharide,grape seed procyanidins,bamboo leaf flavonoids,resveratrol,lycopene and quercetin)in the cryopreservation of animal semen were reviewed in order to provide a theoretical basis for further study on the mechanism of oxidative damage of livestock spermatozoa.
