Abstract

The lempuyang gajah plant (Zingiber zerumbet (L.) Roscoe ex Sm.) is a plant that is widely used as a treatment for desease. The purpose of this study was to determine the toxic effect of the ethanol extract of lempuyang gajah (Zingiber zerumbet (L.) Roscoe ex Sm.) on levels of bilirubin and alkaline phosphatase (ALP) in the liver of mice (Mus musculus). The type of research used is descriptive quantitative with laboratory experimental methods. The mice were divided into 5 groups including normal control, negative control, dose of 4000 kg-1, 5000 kg-1 and 6000 kg-1. then observed the toxic symptoms, macroscopic, levels of bilirubin and alkaline phosphatase. The results of the phytochemical test showed that there were compounds of alkaloids, flavonoids, saponins, phenolics, steroids, triterpenoids and tannins. The results of macroscopic observations showed that the liver was still in a normal condition. The results of the One Way Anova test on bilirubin and alkaline phosphatase levels did not show any significant effect (p>0,05) influence between the normal control group, negative control, doses of 4000 kg-1, 5000 kg-1 and 6000 kg-1, so it can be said that all experimental animals had the same condition.

Abstract

Turmeric (Curcuma longa L.) is an herbal plant that has many benefits as a treatment, including during the COVID-19 pandemic, one of the mechanisms of inhibition of SARS CoV-2 is to inhibit the attachment of ACE2 with Spike. The binding of the spike protein to the ACE2 receptor will produce conformational changes in the S protein, this study was conducted using an in silico method (computational analysis) which aims to determine the potential efficacy of Turmeric and its effectiveness in inhibiting the Delta variant of SARS CoV-2. The active compound contained in Turmeric (Curcuma longa L. ) obtained from the KNApSAcK database To determine compounds that can have potential and have good effectiveness in inhibition of the Delta Variant of SARS CoV-2, an analysis was carried out by looking at the binding energy and conformation changes that occur at the sticky point in each compound. Three-dimensional structure of SARS CoV-2 Varian Delta downloaded from the Protein Data Bank with PDB code 7V8B. Based on the analysis carried out, it was found that the compound (E)-nuciferoll has the lowest binding energy value of -1212.59 kcal / mol and is located at the initial attachment but cannot change the conformation, but from the sticky point of the compound (E)-nuciferol lies in the initial attachment of RBD-ACE2.
