Test on Ethnopharmacology: Traditional Medicine and Drug Discovery

Question 1: Archeology is explicitly listed as a discipline directly related to ethnopharmacology.

A. Ano

B. Ne

Explanation: The study materials list Pharmacognosy, Ethnomedicine, Phytochemistry, Chemical ecology, and Ethnobotany as disciplines related to ethnopharmacology. Archeology is mentioned as part of the broader multidisciplinary approach for ethnobotany and ethnopharmacology, but not specifically as a *discipline related to ethnopharmacology* in the dedicated section.

Question 2: According to the provided study materials, what does ethnopharmacology primarily explore?

A. How ethnic and cultural groups use plants, fungi, animals, microorganisms, and minerals as traditional medicines.

B. The branch of medicine concerned with how artificial or endogenous molecules interact with living organisms.

C. Forms of shared environmental knowledge, beliefs, and techniques for productive activities.

D. The relationship between plants and people, as a branch of ethnobiology.

Explanation: The study materials define ethnopharmacology as exploring "how ethnic and cultural groups use plants, fungi, animals, microorganisms and minerals as traditional medicines." Option 1 directly reflects this definition. Options 2, 3, and 4 define pharmacology, ethnoscience, and ethnobotany, respectively, as stated in the materials.

Question 3: The ethanol extract from Artocarpus blancoi demonstrates greater antibacterial effectiveness against Bacillus cereus than Ciprofloxacin.

A. Ano

B. Ne

Explanation: The minimum inhibitory concentration (MIC) for Artocarpus blancoi against Bacillus cereus is 64 μg/ml, while for Ciprofloxacin it is 1 μg/ml. A lower MIC indicates greater effectiveness, so Ciprofloxacin is more effective.

Question 4: Based on the "A PHILIPPINES CASE STUDY" materials provided, which of the following statements about medicinal plants used for diarrhea treatment are accurate?

A. Nineteen medicinal plants were collected between 2017 and 2019 for the treatment of various gastrointestinal complaints.

B. The plant Artocarpus blancoi (Antipolo /Tipolo) fruit demonstrated antibacterial activity against Bacillus cereus (BC) with a MIC of 64 μg/ml.

C. The study exclusively focused on identifying the active constituents using techniques like Nuclear Magnetic Resonance (NMR) spectroscopy and High-Performance Liquid Chromatography (HPLC).

D. Ciprofloxacin was used as a reference for antibacterial activity, showing a MIC of 1 μg/ml against Clostridium difficile (CD).

Explanation: The study materials indicate that '19 medicinal plants used for treatment of diarrhea, dysentery, abdominal pain and other gastrointestinal complaints - collected in the period 2017 - 2019', making option 0 correct. The table shows 'Artocarpus blancoi Antipolo /Tipolo Fruit' has a 'Bacterium//MIC (μg/ml) BC' value of '64', making option 1 correct. The materials state 'Ciprofloxacin - - 1 16 1 2' for MIC values, with '1' corresponding to 'CD', making option 3 correct. Option 2 is incorrect because the Philippines case study focuses on 'In vitro antibacterial and cytotoxic effects of ethanol extracts' and does not detail the identification of active constituents using NMR or HPLC; those techniques are mentioned in a different study on Paulownia tomentosa.

Question 5: The broth macrodilution method is used for the determination of antimicrobial activity.

A. Ano

B. Ne

Explanation: The study materials list the Broth macrodilution method as one of the 'Methods of determination of antimicrobial activity'.
