The impact of compounds isolated from Ocimum sp. on apoptotic activity of osteoclast

Periodontal disease has multifactorial etiology. The immune response to the microbial challenge leads to osteoclast activation and resorption of the alveolar bone, resulting in tooth loss. Compounds isolated from Ocimum americanum and Ocimum basilicum were analyzed for apoptotic activity towards osteoclast in this study. Steam distillation was used for the extraction of essential oils (EOs) from dry leaves and flowers....
