Essential Oils

Valdir Florêncio da Veiga Jr. is a chemical engineer with a Master's and Doctorate in chemistry of natural products, mainly from the Amazon region, seeking the sustainable use of forest biodiversity. Biotechnological approaches for increasing the value of residual biomass obtained from essential oil and fixed oil extraction have been the focus of his studies, with potential uses in cosmetics, food, and industrial additives. Currently, he is a professor at the Military Institute of Engineering in Brazil, studying natural products.Isiaka Ajani Ogunwande is a recognized specialist in the field of natural products, particularly the chemistry of essential oils. He graduated from Obafemi Awolowo University, Ile-Ife and the University of Ibadan. He has been the author and co-authors of 320 scientific works on natural products including 291 publications on essential oils in journals and books on plants growing in Japan, Nigeria, South Africa and Vietnam. He was awarded Conference of All Muslim Organizations Scholarships, Third World Academy of Sciences Fellowship, Leverhulme Postdoctoral Fellow, Japan Society for Promotion of Science Fellowship, Chinese Academy of Sciences/Third World Academy of Sciences (CAS-TWAS) Visiting Scholars and TETFund, Nigeria, Research Grant. He is the Founder, Society of Essential Oil Distillers and Analysis of Nigeria.José L. Martinez is a chemical biologist from the University of Santiago of Chile, MSc from Pontifical Catholic University of Chile. In 2022 he received the degree of Doctor Honoris Causa in Peru for his contributions to the dissemination and development of Latin American medicinal plants. He also received a tribute in Mexico.
