Biotechnological potential of essential oils from different chemotypes of Lippia alba (Mill.) N.E.Br. ex Britton & P. Wilson
This study reports the biotechnological importance of seven Lippia albaspecimens collected in different places in Brazil, and evaluation of some activities as larvicidal against Aedesspp., antifungal against dermatophytes; cytotoxicity against SNB-19 (astrocytoma), HCT-116 (human colon) and PC-3 (human prostate) cancer cell lines, and inhibition of the enzyme acetylcholinesterase (AChE).The essential oils, whose extraction yield was about 1.24 w/w ± 0.9%, showed differences in their chemical composition and considered as chemotypes. The essential oils containing neral and geranial as main constituents showed better action against HCT-116 cell lines (IC50 value was 9.22 μg/mL), larvicidal activity against arbovirus vectors (LC50 value against A. aegyptiwas 1.59 μg/mL) and inhibition of AChE (halo inhibition zone was 1 cm). The essential oils containing mainly monoterpenoids showed better antifungal action with MIC values range from 0.15 to 1.25 mg/mL. This chemical and biological characterization may be useful for biotechnological applications.
期刊介绍:
The Boletín Latinoamericano y del Caribe de Plantas Medicinales y Aromáticas (BLACPMA), [Latin American and Caribbean Bulletin of Medicinal and Aromatic Plants]; currently edited by the publishing house MS-Editions, is a bi-monthly international publication that publishes original peerreviewed research in the field of medicinal and aromatic plants, with nearly 20 years of experience. BLACPMA is a scientific journal that publishes two types of articles: Reviews (only in English) and Original Articles (Spanish or English), its main lines of action being agronomy, anthropology and ethnobotany, industrial applications, botany, quality and standardization, ecology and biodiversity, pharmacology, phytochemistry, pharmacognosy, regulatory and legislative aspects. While all areas of medicinal plants are welcome and the experimental approaches used can be broad and interdisciplinary; other areas of research that are not mentioned depend on the Editorial Committee for their acceptance.
