摘要

Campomanesia sessionliflora O.Berg是一种药用植物，在文献中很少有研究。本文分析了卤虫浸出液的抗氧化活性、防晒因子（SPF）和毒性，以及浸泡和浸渍卤虫叶制备的水提取物中酚类化合物、黄酮类化合物和单宁的含量。浸泡过程中酚类化合物和黄酮类化合物含量较高，两个样品的单宁含量相同。提取物的LD50相似，在盐藻试验中均被认为是低毒的。输液SPF为9.98，而浸渍SPF为6.74。浸泡后次级代谢产物含量和抗氧化活性较好，输液SPF较好。这些提取物具有并入多功能产品的潜力。

Photoprotective action, antioxidant activity, and toxicity of aqueous extracts of Campomanesia sessiliflora O. Berg

Campomanesia sessiliflora O. Berg is a medicinal plant that is object of very few studies in the literature. In this context, the antioxidant activity, sun protection factor (SPF) and toxicity in Artemia salina Leachs were analysed, as well as the contents of phenolic compounds, flavonoids and tannins in aqueous extracts prepared by infusion and maceration of C. sessiliflora leaves. Maceration showed higher levels of phenolic compounds and flavonoids regarding infusion and the two samples had the same tannin content. The LD50 was similar for the extracts, both were considered as low toxicity in the test with A. salina. Infusion presented a SPF of 9.98, while maceration presented a SPF of 6.74. Maceration presented better contents of secondary metabolites and antioxidant activity and infusion presented a better SPF. The extracts have the potential of incorporation into multifunctional products.
