AbstractAnemopsis californica, native to the Southwest US, is commonly known as yerba mansa. The leaves and roots have traditionally been used to alleviate pain, inflammation, and fungal infections. Isolation of leaf volatiles of A. californica (Hook. & Arn) was performed using steam distillation and solid phase microextraction (SPME). GC followed by mass spectral and flame ionization detection were used for identification and quantification. The most abundant compounds in the steam distillation were: elemicin (53.1%), piperitone (11.0%), and methyl-eugenol (6.9%). The most abundant compounds detected in SPME extracts were piperitone (16.2%), elemicin (13.2), alpha-pinene (11.7%), 1,8-cineole (10.5%), beta phellandrene (8.6%), (E)-caryophyllene (8.2%), methyl-eugenol (5.1%) and sabinene (5.1%). The essential oil exhibited antimicrobial activity against: Staphylococcus aureus, Streptococcus pneumoniae and Geotrichim candidum.
