A supplier sends over a specification marked 10:1 botanical extract<\/strong>. What does that actually tell us? Ten parts of starting plant material went into making one part of extract, on the basis the supplier used for the calculation. That’s it. The number doesn’t promise ten times the active compounds, and it certainly doesn’t tell us everything we need to know about the powder.<\/p>\n\n\n\n

Now picture two quotations sitting side by side. Both say 10:1. Both look reasonable. But one supplier means genuine botanical extract; the other means a commercial powder containing maltodextrin. If we compare those prices by the kilogram without asking another question, we may be comparing two rather different ingredients.<\/p>\n\n\n\n

So let’s unpack the numbers the way a sourcing or formulation team actually needs to: what went into the extractor, what came out, what the manufacturer added afterward, and what the Certificate of Analysis can\u2014and cannot\u2014prove.<\/p>\n\n\n\n

What Does a Botanical Extract Ratio Mean?<\/h2>\n\n\n\n

The basic idea is a mass relationship. In technical documents, you may see the name Drug-to-Extract Ratio<\/strong>, shortened to DER<\/strong>. The word drug<\/em> here comes from pharmacopoeial terminology for herbal material. It doesn’t mean the botanical ingredient is a pharmaceutical drug.<\/p>\n\n\n\n

Extract ratio = Weight of starting botanical material : Weight of extract obtained<\/strong><\/p>\n\n\n\n

Say we start with 10 kg of dried plant material<\/strong> and recover 1 kg of native dry extract<\/strong>. We call that a 10:1 native DER<\/strong>. If we recover 1 kg from 4 kg<\/strong> of starting material, it’s 4:1<\/strong>. Easy enough.<\/p>\n\n\n\n

But here’s the question we always want answered before accepting the calculation: Did the supplier start with fresh material or dried material?<\/strong><\/p>\n\n\n\n

Fresh leaves and dried leaves carry very different amounts of water. That matters. A dramatic-looking number can sometimes reflect moisture removal rather than a dramatic increase in a constituent we’re interested in.<\/p>\n\n\n\n

Take a concentrated aloe vera extract powder<\/a> as an example. Before we read too much into the declared ratio, we need to know whether the manufacturer used fresh inner-leaf material, dried material, or another clearly specified solids basis. Without that detail, a comparison can go sideways fast.<\/p>\n\n\n\n

We should also expect some natural variation. Plants aren’t manufactured to identical chemical profiles, and extraction yields can shift between batches. An honest specification may show a range such as 7\u20139:1<\/strong> rather than an implausibly perfect number for every lot.<\/p>\n\n\n\n

Native Extract Ratio vs. Finished Extract Ratio: The Carrier Dilemma<\/h2>\n\n\n\n

This is the distinction we would put near the top of any supplier-comparison sheet.<\/p>\n\n\n\n

A native extract<\/strong>, sometimes called a genuine extract<\/em>, consists of the botanical material recovered through extraction before the manufacturer adds excipients. A finished extract powder<\/strong> may combine that native extract with processing or handling ingredients such as maltodextrin or silicon dioxide.<\/p>\n\n\n\n

And no, a carrier isn’t automatically a problem. Some botanical extracts are stubbornly sticky, absorb moisture, or don’t dry into a practical powder without help. A carrier can serve a legitimate technical purpose. The trouble starts when nobody tells the buyer how much is there.<\/p>\n\n\n\n

Here’s a simple production example. The arithmetic matters more than the marketing name.<\/p>\n\n\n\n\n\n\n\n\n\n\n\n
Production step<\/th>\n\n\n\nWeight<\/th>\n<\/tr>\n<\/thead>\n\n\n\n
Dried botanical material entering extraction<\/td>\n\n\n\n10 kg<\/td>\n<\/tr>\n\n\n\n
Native extract solids recovered<\/td>\n\n\n\n1 kg<\/td>\n<\/tr>\n\n\n\n
Maltodextrin added afterward<\/td>\n\n\n\n1 kg<\/td>\n<\/tr>\n\n\n\n
Finished commercial powder<\/td>\n\n\n\n2 kg<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n\n\n\n

Now we have two different ratios<\/strong> for that one batch:<\/p>\n\n\n\n
