Quantification of α-acids in the raw material of humulus lupulus by conductometry

The amount of α-acids in the collective fruit, foliage and granules in the samples of cultivated and wild varieties of Humulus lupulus has been quantified. The results of the undertaken study have shown that no α-acids has been found in the foliage of the cultivated and wild varieties of Humulus lupulus. In the collective fruit of the cultivated variety of Humulus lupulus such as «Mikhailovskiy», «Sumer» and «Podvyazniy» which are grown by JSC Agrocompany «Resursy» (the city of Cheboksary) the amount of α ? acids was found to be

5.1 - 7 % and in the collective fruit of the wild variety of Bashkortostan flora the amount of α-acids was 1.7 - 3.6 %. Therefore, wild species of Humulus lupulus containing more than 3.5 % can be recommended for the use in medical practice and food industry.
