Methanolic extracts from the aerial and root parts of in vitro cultured Artemisia alba and the aerials of in vitro cultured Clinopodium vulgare, Hypericum tetrapterum, H. richeri  and the endemic H. rumeliacum  were evaluated for their nitric oxide scavenging capacities. Extracts of H. rumeliacum, H. richeri and H. tetrapterum exhibited remarkably higher activity (0.18, 0.17 and 0.97–1, respectively) compared to C. vulgare and A. alba (SC50 = 3.45, 2.93 and 2.62–1, respectively). Vitamin C (a reference compound), exhibited activity of 0.26–1. The presented results are indicative of the high therapeutic potential of the extracts derived from the in vitro cultured plants and are a good basis for further more detailed research.
