The 2nd National Seminar on Phytochemistry, Pharmacology, and Phytotherapy (SNPPP-2) “Biodiversity at the Service of Start-ups” is a scientific event organized by the Laboratory of Chemistry and Environmental Chemistry (LCCE) in collaboration with the Faculty of Matter Sciences, the Algerian Chemical Society (ACS), as well as the National Union of Pharmacists (SNAPO). The main objective of this scientific event is to create a space for meeting and discussion between teacher-researchers and PhD students working in the fields of chemistry, pharmacy and biology. This seminar encourages cooperation and exchanging ideas on new scientific and biotechnological researchs in these important areas. During this seminar, participants will have the opportunity to present their research work in the form of oral communications and/or posters, to share their ideas, and to benefit from the experiences of other participants in different proposed topics. We also aspire to establish new collaborations and research projects in different areas of chemistry, pharmacy and biology
