Myrmecodia plant or ant-nest plant is from Rubiaceae family. Rubiaceae are mainly tropical woody plants, consist mostly of trees and shrubs and can be found in temperate regions. Myrmecodia platytyrea (MyP) are believed to have medicinal value.  This study was designed in order to investigate the effect of MyP extract as anti hypercholesterolemic agent. The results showed that treatment of MyP can significantly reduce (p<0.05) low density lipoprotein (LDL) compared to negative control group. The extract was significantly increase (p<0.05) high density lipoprotein (HDL) concentration compared to negative control group. Besides that, MyP increased fecal cholesterol and fecal bile compared to normal control group. It was also found that lipid profile was significantly decreased (p<0.05) in MyP treatment group. All biochemistry data showed that MyP water extract was not toxic at all.

In this study, Myrmecodia platytyrae (MyP) water extract was investigated to explain the antioxidant property and its safety. Water extract of MyP was prepared and tested for ORAC for each batch of preparations. The MyP water extract was administered daily onto three groups of experimental animals which were Low Dose (LD), Medium Dose (MD) and High Dose (HD) groups for a period of consecutive 28 days according to the OECD GLP guideline (OECD TG 407). The ORAC results showed that MyP water extract has an antioxidant activity for each batch. The subchronic toxicity test showed that MyP water extract product has no observable sub-chronic toxic effect on Sprague Dawley rats. The body weight of rats increased along with proportional food and water intake. In the same way, all hematological, biochemical parameters as well as histopathological observation do not show any abnormal finding. Gross observations, feed and water consumption, urine strip test and animals’ weight during necropsy did not show any difference compared to the control group. In conclusion, MyP water extract is suggested to have a broad safety margin in experimental animals.
