近年来,随着核科学技术的不断发展,核技术的广泛应用,核辐射损伤得到了人们的普遍关注。重离子束治癌的发展以及载人太空探索的需要,使得重离子对人体组织的损伤效应成为人们的关注热点。与此同时,各种低毒高效的辐射药物的开发也引起了人们的极大兴趣。目前,虽有一些传统的辐射防护药物,但大多数具有较强的毒性,鉴于中草药毒性低,药源广等特点,人们希望从传统的中草药中开发出毒性低、高效的辐射防护剂。香兰素(Vanillin)是一 In recent years, with the continuous development of nuclear science and technology and the widespread application of nuclear technology, nuclear radiation damage has drawn people’s widespread concern. The development of heavy ion cancer therapy and the need of manned space exploration make the damage effect of heavy ions on human tissue become a hot spot. At the same time, a great deal of interest has been drawn from the development of a variety of low-toxic and highly effective radiation drugs. At present, although there are some traditional radiation protection drugs, most of them have strong toxicity. In view of the low toxicity and wide source of traditional Chinese medicines, people hope to develop low toxicity and high efficiency radioprotectants from traditional Chinese herbal medicines. Vanillin is one
