Abstract

Plasmodium species are the infectious agents that are responsible for malaria, a disease that claims the lives of approximately 400,000 people annually. The fact that drug resistance against malaria is on the rise suggests that new antimalarial compounds need to be discovered. It is well known that medicinal plants present the best opportunity for the identification of novel antimalaria chemicals. Both the Andrographis paniculata (Burm.f.) and Peperomia pellucida (L. Kunth) species have been tested for their antiplasmodial ability against the Plasmodium falciparum strain. The P. pellucida (L. Kunth) species has also been subjected to in vitro and in vivo biological research. P. pellucida was used to isolate the steroid known as 3-hydroxy-24-ethyl-5,22-cholestadiene (1) and the triterpenoid known as 3-hydroxy-9-lanosta-7,24E-dien-26-oic acid (2). Both compounds were then tested for their activity in vitro. In the mice model, triterpenoid 2 had a substantial chemo-suppressive impact.

Abstract

This research aims to determine the chemical characteristics of coconut shell liquid smoke and analyze the effectiveness of using liquid smoke in reducing Pb metal contamination in skipjack tuna (Katsuwonus Pelamis). Grade 2 liquid smoke from coconut shells is produced by the Pulubala IKM center through the stages of pyrolysis and distillation. This study employs a completely randomized design (CRD) with two replications. To determine the chemical characteristics of the liquid smoke, the analyzed methods include pH measurement, phenol content, total acidity, protein content, organoleptic value, and the chelating power of heavy metal Pb with variations in the concentration of liquid smoke test solutions AC (undiluted liquid smoke), AC2, AC4, AC6, and AC10 (liquid smoke with the addition of distilled water at 2%, 4%, 6%, and 10%). The results show that the best treatment is obtained from coconut shell liquid smoke with AC concentration (undiluted liquid smoke) having the best characteristics, namely a pH value of 4, phenol content of 1.6469%, total acidity of 14.94 mg/mL, protein content of 0.6083%, and a chelating power for heavy metal Pb of 97.32%. The results of the organoleptic test indicate that overall, the highest score was obtained with a neutral value at the concentration of AC2 (liquid smoke with the addition of 2% distilled water).
