Plant Extraction Methods - Decoction and Maceration | JPTV

Hey! Are you even curious about how MX3 gets "xanthone" from mangosteen or how Myra-E extracts "d-alpha tocopherol (vitamin E)" from soybean oil? Typically, we see in the advertisements of whitening, antiaging, and food supplement products the terms like "ascorbic acid (vitamin C)" in Ceelin, "resveratrol" in Slenda, or "glutathione" in Vitapack Megawhite. These terms are names of bioactive compounds that exhibit tons of health benefits like antioxidant, anti-inflammatory, antibacterial, antifungal, antidiabetic, antiviral, and even anti-cancer properties.

Pharmaceutical scientists extract these bioactive compounds from different natural sources for medicinal purposes using different extraction methods. If you are curious about how they do it, watch this vlog. #JPTV #NeverStopLearning

Do you have published paper that i can cite you on this method? By the way, thank you for sharing this! Very much appreciated.

Wow this is 3yrs video and it's helpful to me this year thank you so much Doc.

2:43 please.. have a question.. what type of solvent you have used for maceration ?
I have another question : for ex if we use ethanol-water as solvent, after the extraction we eleminate the ethanol first using ratary-evaporator, but how we eliminate water fraction ?
Thanks brother for sharing this video !!

Thank you, sir! This has helped me in understanding better the procedures I need to do for my thesis.💚

Hehe! Kawa ka mo ng mga video about make shift lab equipment since hindi naman lahat may boiler at vacuum ek ek. Para sa mga mahilig mag experiment pero wala pambili ng equipment. Hehe

Hello po! Thank you po for the informative video! It really helped us understand the methodology needed to conduct our research. May we ask po how much plant material (in grams) do we need to use to extract 5mg, 16.25mg, 35mg of the pure extract? And also how much solvent is required for maceration?

We are currently struggling to compute the amount of grams of plant material to get the according milligrams (We tried using the vague references in the video but still struggled). Also po we need to compute the amount of solvent used for maceration and the ratio is 1:2 (w/v). The volume of our final solution is 50ml and we need to dilute it for 3 concentrations (10%, 32.5%, 70%). After solving this, the grams needed for the dilution is already stated above (5mg, 16.25mg, 35mg).

To conclude, our group wants to know how much grams of plant material is needed for the final product using the 1:2 ratio for maceration and how much solvent is required. **We know that this request is a bit hard, if it cannot be answered, do you have any suggestions po on how we can compute it?** Thanks po doc!!

That was so helpful man! Thank u doc. Stay immensely blessed ✨

Geez Louise, and we all wonder why our skincare or medicinal extracts costs so much; well....Exhibit A, ladies and gentlemen!! I need to remember this AMAZING process, shown to us by the kind Doctor. the next time I'm shopping for extracts and whining that they "just cost too much" at $14.95 a bottle; am I right? Thank you, Doc, for opening my eyes and giving me some perspective!

[darrenacharon]

big help gyud ni sa ako specially sa school.. thank you kuya John Paul ☺️☺️☺️

[johnbernardlicot]

Hi, very informative video, tanong lang is there chance na yung plant extract is very oily? Kasi we did it using a seed and the extract was very oily

[adhikery]

impressive and practically well-teaching video. thanks

[gutsandglory]

Man I like this laboratory. Thanks for the video. This is the third time I am watching this. So after extraction how do you fortify your product with the extract?

[ladymichellebarlisan]

hello sir! What if we don't have rotary evaporator. Can u suggest some alternative for the extraction?

[HonandJo]

Nice content lalo na for students. Very helpful 👏🏻👏🏻👏🏻👏🏻

[KayceeJ]

Thank you for sharing your knowledge po ☺

[MommahJuu]

This is very informative! Support ito, grabe! <3

[Angrybird-eqbk]

one thing i want to ask, can you please share the procedure of solvent extraction for plant bark extract, for its phytochemical analysis.

[hyfahassan]

This video is very insightful. May i ask if you don’t mind, when using the decoction method what is the reasoning behind freezing? And if necessary how will it be possible to obtain a liquid form of the extract instead of the powder? Thank you for any response and for this video.

[siddhip]

Thnq for such a valuable video
Sir can u pls resolve my quiery...if we want to prepare a plant extract (for any activity) for whom we dnt have any idea about its solubility then which solvent will we use?

[princearellano]

Hello po! Just a question, kung 7.5mL po ‘yung solution nila (filtered macerated leaves) mga ilang mL po kaya ‘yung magiging final product (extract itself)? Thank you po!
