>An amount of 15 g of the bark powder was treated with 6 g of calcium hydroxide and 15 mL of sodium hydroxide (5%).

>A mean value of 5.4 ± 0.1% of yield obtained from MIEL experiments validated the reponse surface methodology model, representing a comparable yield if compared to conventional Soxhlet extraction (5.7%).
15 grams of bark x 0.054 = 0.81g of alkaloids of which

>The results by MIEL are similar to those obtained by Soxhlet. Extract composition was equivalent in terms of quinine (~15%), quinidine (~2.9%), cinchonidine (~22%) and cinchonine (~37%) for both extraction methods but also in terms of yield (5.7%).
15% of that is actually quinine
0.81 x 0.15 = 0.1215g of quinine extracted from 15g of material
which means that assuming perfect bioavailability you would need to consume
1g of material/ 0.1215 quinine yield = 8.2304 * 15 = 123.45g of cinchona bark consumed PER FUCKING DAY
7.71 pounds of cinchona bark PER DAY
