The students were trying to identify the antioxidant compounds present in a particular plant extract. However, their results didn't match the expected values. The professor decided to take a closer look and discovered that the students had mistakenly used a different plant extract, which didn't contain the expected flavonoids.
As the students worked on the task, they consulted Trease and Evans' Pharmacognosy, 15th edition, which provided them with valuable information on the phytochemical analysis of plant extracts. They discovered that the mystery plant was actually a species of Rosmarinus, which is known to contain a high amount of carnosic acid, a potent antioxidant.
It was a typical day at the university's pharmacognosy lab, where students were busy studying the medicinal properties of various plants. Professor Thompson, a renowned expert in the field, was teaching a class on the pharmacological importance of flavonoids. As she lectured, she noticed a group of students looking puzzled.
To resolve the issue, Professor Thompson assigned the students a task: to analyze the chemical composition of the mystery plant extract using various chromatographic and spectroscopic techniques. The goal was to identify the antioxidant compounds present in the extract and understand their pharmacological significance.

Thank you Mike, super kind 🙂
Is it allowed to pick up a discarded singleton in order to mahjong?
Typically no, but the game has many variations depending on region.
Hi! Thank you for your clear instructions on how to play mahjong!
Is it common to play the game without the flowers? I think there are eight of them. Thank you in advance for your response!
都可以!Flower tiles are considered optional typically Judi 🙂
Glad you enjoyed the guide.
Use to play years ago we lived in Boca raton FL played 3 times a week. We moved to Kentucky no one played so I play bridge now. I miss my tiles,would like to’ play again . I -have a set . Would like to learn again.
