and var. decoctions were screened for diverse bioactivities, including the ability to counteract oxidative and inflammatory events, as well as to act as cytotoxic and antimicrobial agents. Both extracts showed good activities and that of origin was particularly effective regarding the ability to prevent lipid peroxidation and to prevent nitric oxide (NO●) production in lipopolysaccharide (LPS)-activated murine macrophage RAW 264.7 cell line (EC = 50 μg/mL). Moreover, it displayed high cytotoxic capacity against hepatocellular carcinoma HepG2, cervical carcinoma HeLa, and breast carcinoma cells MCF-7, but comparatively low effects in porcine liver primary cells, which highlights its selectivity (GI = 41-60 μg/mL vs. 362 μg/mL, respectively). Further, it exhibited inhibitory and lethal potential against a panel of Gram-positive and Gram-negative bacteria. It is possible that the bioactive properties of the two extracts are associated to their phenolic components and, in the particular case of , to its richness in phenolic terpenes, namely in rosmanol, hydroxycarnosic acid and a derivative of sageone, which were found in the extract.
对[植物名称]及其变种的水煎剂进行了多种生物活性筛选,包括对抗氧化和炎症反应的能力,以及作为细胞毒性剂和抗菌剂的作用。两种提取物均显示出良好的活性,其中[植物名称]提取物在预防脂多糖(LPS)激活的小鼠巨噬细胞RAW 264.7细胞系中脂质过氧化和一氧化氮(NO●)产生方面特别有效(半数有效浓度EC = 50 μg/mL)。此外,它对肝癌HepG2、宫颈癌HeLa和乳腺癌MCF-7细胞显示出高细胞毒性,但对猪肝脏原代细胞的影响相对较低,这突出了其选择性(分别为半数生长抑制浓度GI = 41 - 60 μg/mL对362 μg/mL)。此外,它对一组革兰氏阳性和革兰氏阴性细菌表现出抑制和致死潜力。两种提取物的生物活性特性可能与其酚类成分有关,特别是[植物名称]提取物富含酚类萜类化合物,即迷迭香酚、羟基肉豆蔻酸和鼠尾草酸的一种衍生物,这些成分在提取物中被发现。
