Indonesia is known as a country with very high biodiversity, within which are potential medicinal plants that have not been fully explored or utilized. The potential of this natural biodiversity for the health and welfare of the Indonesian community is regarded as high, if it is properly utilized. An example of the potential benefits of these plants is reflected in the types of traditional medicinal plants used by the Mamuju ethnic in West Sulawesi. This research aims to describe the types of plants used as traditional medicines by the Mamuju ethnic group. The study is based on descriptive approach that used a combination of observations, interviews and taxonomy. The results of the study revealed that there are 31 species of medicinal plants used as sources of traditional medicine by the Mamuju ethnic group, of which there are 33 medical herbs used for the treatment of 31 kinds of diseases. The health issues that are addressed through the use of medicinal plants include the treatment of some types of internal diseases, including cysts, cancer, tumors, high blood pressure, ulcers and diabetes; disease symptoms such as itching, swelling, myopic, new injuries and infections. Some traditional medicines are used in relation to onset of menstruation, and postpartum treatment. The plant components that are used for medicinal purposes include roots, stems, stem bark, leaves, flowers, fruit, seeds, rhizomes and tubers. However, the predominant plant component used for medicinal purposes is plant leaves.
The study was conducted to observe the effect of clove leaf methanol extract on the profile of superoxide dismutase (SOD) and malondialdehyde (MDA) in the liver of rabbits under hypercholesterolemia. Nine male New Zealand rabbits were used for this study. They were divided into three groups i.e (1) negative control group, (2) Positive control group (hypercholesterolemic) was fed with diet containing 1% cholesterol for 50 days, and (3) the group was given clove leaf extract and 1% cholesterol for 50 days. The hypercholesterolemic condition decreased SOD activity and Cu, Zn-SOD level, otherwise the increasing of MDA level occurred on the liver of the rabbits in the positive control group compared to negative control group. On the other hand, the third group showed the increase of SOD activity and Cu, Zn-SOD level with clove leaf methanol extract. The best results were obtained in the rabbits treated with clove methanol extract simultaneously for 50 days.
Abstract. This study aims to extract the essential features of Photoplethysmography (PPG) signal of men and women in healthy subjects using Power Spectral Density (PSD) and Detrended Fluctuation Analysis (DFA). A PPG instrument was used to obtain the PPG signal of 15 men and 15 women. Using PSD, four frequency bands were selected to divide the spectral component. The areas within the frequency bands relative to the total area were computed as features of the signals. Furthermore, using DFA, the average fluctuation F(w) was computed. The feature extraction using this technique produced 4 features from different windows. Hurst exponent was calculated to analyse the characteristics of the time series. For comparing the feature extraction techniques, Heart Rate (HR) and Peak to Peak Interval (PPI) were computed. Additionally, F and T tests for all techniques were computed to determine the differences between man and woman features that have been gathered using these two techniques. The results indicate that the features of PPG signals of men and women using PSD and DFA were significantly different. In order to evaluate the results, a clustering analysis was applied to the results using K-means clustering technique. The clustering plots show that the features were well distributed into the two groups.
Abstract. Indian Ash Tree (Lannea coromandelica) is a native plant from Indian and empirically used for pain remedy. The leaves were simply applied on the affected area for external wound, then for internal wound in a way boil the leaves and drink it. The chemical composition of medical plant determined its pharmacology. This research explored the potency of (Lannea coromandelica) by determining its secondary metabolites group. The plant was collected from Makassar, South Sulawesi. The results showed that (Lannea coromandelica) was positive for Saponins, Flavonoids, polifenols and Tannins.Keyword : Indian Ash Tree leaves, Phytochemical, Medical plant.
