EKSTRAKSI DENGAN METODE SOXHLET | BIOLOGI FARMASI - STFI Bandung

Summary

In this video, Anita Nurlitasari from Sekolah Tinggi Farmasi Indonesia demonstrates the process of preparing an extraction using a Soxhlet apparatus. She explains the necessary equipment and materials, including a round-bottom flask, condenser, filter paper, and solvent like water or ethanol. The procedure begins by assembling the Soxhlet apparatus, adding the solvent, and placing the plant material in the extraction chamber. The video walks viewers through each step, emphasizing the importance of maintaining the right temperature for effective extraction until the solvent is clear, indicating the completion of the process.

Takeaways

• 😀 The video is presented by Anita Nurlitasari from Sekolah Tinggi Farmasi Indonesia.
• 😀 The focus of the video is on explaining the process of Soxhlet extraction of Sinabung.
• 😀 The required tools include a round-bottom flask, condenser, Soxhlet extraction apparatus, and some other common lab tools like scissors and filter paper.
• 😀 A solvent (water or ethanol) is used in the extraction process, along with 250 grams of simplisia (raw material).
• 😀 The first step is assembling the Soxhlet apparatus by attaching the round-bottom flask and adding some solvent to it.
• 😀 The simplisia should be wrapped in filter paper and placed in the Soxhlet thimble before being added to the extraction apparatus.
• 😀 The condenser is attached to the top of the Soxhlet extraction tube, and the apparatus is secured in place with a piece of string or thread.
• 😀 The next step involves adding the remaining solvent into the extraction tube and starting the heating process.
• 😀 The heating should be controlled, and the temperature should be set according to the required extraction conditions.
• 😀 The extraction continues until the solvent in the extraction tube becomes clear, indicating that the desired compounds have been fully extracted.
• 😀 The video concludes with the expectation that the extraction process will be completed once the solvent becomes transparent, signaling the end of the extraction cycle.

Q & A

What is the purpose of this video?

The video explains the preparation and extraction process of Sinabung using a Soxhlet extractor, demonstrating the tools and methods involved.

What is a Soxhlet extractor used for in this experiment?

A Soxhlet extractor is used to continuously extract compounds from a solid material using a solvent, which is then heated and cycled through the material until the desired compound is extracted.

What materials are needed for the Soxhlet extraction process?

The materials required include a round-bottomed flask, a Soxhlet extraction apparatus, a condenser, a cotton thread, scissors, filter paper, clamps, a solvent (such as water or ethanol), and 250 grams of the sample material (simplisia).

How do you set up the Soxhlet extractor?

First, you attach the round-bottomed flask to the Soxhlet extractor. Then, add some solvent to the flask, place the sample in a filter paper and insert it into the extraction tube. The apparatus is then set up with a condenser and heated to begin the extraction process.

What type of solvent can be used in this extraction process?

Either water or ethanol can be used as the solvent, depending on the desired compounds to be extracted from the sample.

Why is a condenser used in this setup?

The condenser is used to cool the vaporized solvent, allowing it to condense and return to the round-bottomed flask, maintaining a continuous cycle of extraction.

What is the role of the cotton thread in the setup?

The cotton thread is used to attach the Soxhlet apparatus to the stand, ensuring that the equipment stays secure during the extraction process.

How long does the extraction process last?

The extraction process continues until the solvent in the flask becomes clear or the desired compounds have been fully extracted from the material.

What should be done once the extraction is complete?

Once the extraction is complete, the setup is turned off, and the extracted compounds are collected for further use or analysis.

What is 'simplisia' in the context of this process?

Simplisia refers to the plant material or substance that is being processed for extraction in the Soxhlet apparatus. In this case, 250 grams of simplisia are used for the extraction of Sinabung.
