how to extract compounds from natural plants?

You can have a "crude extract" - no other solutions\nor the :"ethanolic extract " - use ethanol to extract substances\n\nUpon collection of plants, wash carefully and then air dry avoiding the contact of the parts of the plants to by source of contamination.   Then perform extraction by grinding the plant parts and getting crude extract or  using ethanol after grinding to get extract.

It deals with the chemistry of food, for example how much fat, oil, starch, fiber etc is in Corn.  How to extract all of these components from corn.  The shape of the oil molecules, fat molecules etc.  Hope this helps:)

u MUST start up the followin-\n1. WHEAT GRASS EXTRACT (easily available wit all chemists recently)\n2. AMLA -murraba, syrup, or tonic***\n3. ASHVAGANDHA tablets, powder\n4. eat lots of BANANA, beetroot, green stuff\n5. lots n lots of water- 8 to 11 glasses a day.\ntry this regularly for a few weeks n ull have the sure n assured result without ANY side effects.\nkip smilin n trust me , ull b perfectly fine!!\nGOOD HEALTH!!\n:):)

Water and "nutrients" depending on the specific type of cell. Plant cells need inorganic nitrogen compounds (ammonia, nitrate), phosphate, iron, magnesium, manganese, copper,...\nAnimal cells need organic substances like sugars or amino acids (which plant cells can produce on their own) additionally to vitamins and ions (iron, copper, cobalt, zinc, molybdenum, iodine, selenium,...)

I'm not sure I understand your question.  Are you looking for the native plants which are the source of synthesized pharmaceuticals?  Are you looking for natural remedies, as opposed to pharmaceuticals?\n\nMaybe you want to know if certain plants are effective as medication?  Or perhaps you want to know where to get tinctures or other natural plant remedies.

Depends on the ingredient.  Usual procedure is to chop the plant in a blender and extract the active principle with a suitable solvent, and then refine the extract with fractional crystallization, distillation, or other such means.

The method we use to practice at home for making coconut oil is - first select mature coconuts fresh or dried. Then remove the outermost cover including the fibrous part. Split the coconut into halves and let it dry in bright sun. The process of drying continues until the moisture in the coconut flesh disappears and also the coconut gets separated from the shell by it self.Once the coconuts are completely dried they are chopped to small pieces and grinded to extract oil. The extracted oil is then collected after filtration. Also the remainings of the coconut  after extraction is used as a food for the cattle.

I'm assuming you are extracting from an aqueous solvent?  Preferably, you want to increase the polarity of the aqueous solution, such that the solute has less affinity for water than it would for the organic solvent.  This can be done by "salting" the water (increasing the ionic strength by adding an inert salt, a la NaCl).  You then extract the solute with your organic solvent of choice, usually using smaller aliqouts more frequently vs. larger aliqouts (deals with partition coefficient, or how much will get extracted vs. how much remains in the water).  After extraction, the organic solution is usually dried (more often than not by MgSO4 or Na2SO4) and then the solvent is distilled off to yield hopefully pure product.

different ways to do it.  steam distillation, expression, solvent extraction and efleurage. the first is the easiest and what you want to know if you are looking for a how to. Use hot steam, like a steamer, you'll end up with the oil and water.  then separate the oil.  \n\nthe other methods are more complicated, but you do end up with more oil.  but at what price?  second method the is to use pressure or centrifugation. At home, not likely you have anything to make this work.   The third method you use a solvent, but then the oil and solvent are mixed.  You then evaporate the solvent (you can get at a whole foods store to do this) when the solvent is evaporated you are left with a heavy, waxy substance called concrete. Then you have to separate the liquid from the was.  it's great because it is most concentrated from of aroma, but very time consuming and complicated.  That last, efleurage is a really long process using animal fats and alcohol. Although essential oils main usage is in cosmetics and perfumery, many of them do have proved therapeutic properties.

I don't think that is so high the rate (80%).The last survey that I found, was refering a smaller amount.\nThere is always the question, what we define as natural medicine ; if a medicine is natural or not after chemical processing.\nIf I understand well, you want to know the procedure of making medicines from plants. \nWell, there are various ways : \nThe most simple and easy way is to get the essential oil.\nIf you want to experiment which is the part of the plant that contains the active substance, isolate this substance and administer to patients in various dosage forms,in order to formulate a new medicine,then things are more complicated.\n\nIf you mean where to find the natural treatments,that is issues of alternative medicine, well just enter the site \nof a University, ie. Yale University or Alabama University and you can find trustworthy information.\n\nIf you want to give us here,more information in the same message, click on: Add details, that you will find on the top right of the page.
