Unlike Bronya who was worried, Fu Song was happily collecting Artemisia annua all over the world.

But soon he was dumbfounded.

In just half an hour, Fu Song found 17 varieties of Artemisia.

As for which type of Artemisia annua that Grandma Tu used to extract artemisinin, well... the leaves are all green anyway.

This cannot be blamed on Fu Song. There are more than 300 species of Artemisia in the world.

In addition, the leaves of Artemisia are similar, and it is impossible to tell them apart unless you are a professional.

In the end, Fu Song picked up all the wormwood.

At worst, I'll just have to work a little harder and analyze them one by one.

In fact, all Artemisia contains artemisinin, but the content is different. Fu Song only needs to find the one with the highest purity.

He began to experiment.

However...how to do it?

Fu Song was dumbfounded again.

His only experimental experience was his collaboration with Dou Hongyi in the laboratory of Huazhong Agricultural University.

As an assistant, Fu Song played a finishing touch in the experiment.

At that time, he thought it was easy, but now he finds that it is not as simple as he imagined.

But the experimental design was enough to drive him crazy.

Holding a thick reference book, Fu Song muttered, "It would be great if Dou Hongyi were here. He looks carefree, but he's really good at experimental design."

Beside him, Zhang Jiuyue, who had been busy accompanying Fu Song, smiled and said, "It won't work if you call Dou Hongyi over.

As the saying goes, different fields are like different worlds. The other party is an expert in agriculture, but your experiment is related to medicine.

The two don’t go together at all.”

Fu Song: "What should I do? I can't possibly get a doctorate in medicine just for an experiment, right?"

Zhang Jiuyue said helplessly: "I said you are usually so smart, why do you suddenly become stupid at the critical moment?

Isn't there a ready-made doctor of medicine here?"

Fu Song: "You mean Simon?"

"And Bronya!"

Bang!

Fu Song slapped himself in the face and felt really stupid.

Simon was called over by Fu Song: "Apprentice, let me ask you a question. Can you extract medicinal ingredients from plants?"

Simon was stunned: "What did you say?"

Seeing that Simon didn't seem to understand, Fu Song was a little disappointed: "No, forget it."

He didn't question it. After all, everyone has their own expertise, and it was indeed a bit difficult to ask an expert in surgery to study drug analysis.

Then I heard Simon say, "Extracting pharmaceutical ingredients from plants was just the basic work I did when I was a freshman.

I stopped doing this kind of hard labor that requires no technical skills ten years ago, and now I hand it all over to my students."

Fu Song: “…”

Okay, before I knew it, I was actually caught by this guy.

"Can you still do it now?"

Simon: "If you ask a high school student to do addition and subtraction within ten, do you think he can get it right 100% of the time?"

Fu Song: “…”

You can't just talk properly, right?

He said directly, "Now I have a task for you. Do you see these wormwoods? Find a way to separate their chemical components. The finer the better.

Remember, separation must be done at low temperatures."

Artemisinin is easily decomposed at high temperatures. Once the temperature exceeds 80

℃, all efforts will go to waste.

Fu Song thought that what he said was not clear enough, and was about to add a few more words when he heard Simon say: "No problem, I guarantee to complete the task."

He quickly made a table, and then separated the roots, stems and leaves of all the wormwood he picked with a technique that dazzled Fu Song.

Crushing, filtering, evaporating, dissolving, extracting...

Simon's hands worked like magic, producing hundreds of samples in just half a day.

Fu Song couldn't help but give him a thumbs up: "As expected of a top student from Harvard Medical School, awesome!"

Simon pointed to the crude experimental equipment in front of him and said, "Please don't insult my university. Thank you!"

Fu Song: “…”

But he no longer had time to talk nonsense with the other party, because lines of red text appeared in Fu Song's eyes.

That’s right, this is also one of the reasons why Fu Song dared to extract artemisinin on site.

Generally speaking, if you want to accurately analyze the ingredients of a certain drug, you need very sophisticated instruments.

This is simply impossible in African tribes with poor facilities.

But it’s different when you use your own eyes.

As long as he can roughly separate these Artemisia, Fu Song can determine which Artemisia has a higher artemisinin content.

Soon, Fu Song took out experimental group No. 67 and asked Simon: "What kind of wormwood is it?"

Simon said, "Artemisia annua."

Fu Song nodded: "That's it."

He finally breathed a sigh of relief.

Many people subconsciously think that since Grandma Tu won the award for artemisinin, the most effective artemisinin must be extracted from the purest Artemisia annua.

In fact, artemisinin extracted from Artemisia annua is only effective against Plasmodium vivax malaria, and has little effect on falciparum malaria.

Artemisinin extracted from Artemisia annua is not only effective against Plasmodium vivax malaria, but also against falciparum malaria.

It’s just that Grandma Tu was the first to discover artemisinin, and artemisinin was discovered secondary to the discovery of artemisinin, so it is not as famous as artemisinin.

He found Chief Dies and asked him to gather his tribesmen to pick a large amount of Artemisia annua.

"Diez, I won't let everyone work in vain. I'll buy all the Artemisia annua they pick."

Unexpectedly, Dies shook his head and said, "Dear Fu, I know what you are doing.

So please rest assured that my people are happy to serve, free of charge."

"Thank you so much." Fu Song did not refuse. He turned around and discussed the purification plan with Simon.

The extraction solvents for artemisinin are divided into two types: ether and alcohol. Fu Song chose alcohol which is easily available.

When he was ready, Dies just came back with his tribesmen carrying a large amount of Artemisia annua.

After another busy day, Fu Song took out a beaker with half a cup of liquid in it.

Putting the beaker in front of Bronya, Fu Song clapped his hands: "Here, the new medicine you want, got it."

Bronya looked at him suspiciously: "What new medicine?"

"Of course it's a new drug for treating malaria!"

Bronya opened her mouth in surprise: "So fast?"

It’s not that she doesn’t believe Fu Song, but it’s only been one day since she proposed the conditions.

The development of a new drug will take several months even at the fastest speed. It is considered good if a rough plan can be developed in one day.

Fu Song laughed out loud: "Special matters require special treatment. Time is money. One more day means millions in losses. I won't do anything careless."

Seeing that Bronya was still in a daze, Fu Song said again: "Do you doubt the effect of this thing?

Weren't those people all patients before? Just try it with them and you'll know."

Bronya finally came to her senses and quickly stood up and rushed towards the isolation area.

Her little sister was there too. Bronya had just visited her half an hour ago and she was in critical condition.
