Abstract:Drone brood homogenate is a little-known bee product used in folk medicine to treat various health problems. It is a very nutritious milky substance with high content of nutrients: proteins, lipids, fatty acids, carbohydrates, vitamins (A, B, E and D), and minerals. Moreover, when collected on early stage of larvae development, it is, most of all, rich source of sex hormone (testosterone, progesterone and estradiol). Some beekeepers consider drone brood as a waste product, although in some countries they use i… Show more
“…Drone brood homogenate, less commonly called drone milk, is a little-known bee product that is often disregarded in articles relating to beekeeping products [ 1 , 2 , 3 ] or marginalized with a brief mention [ 4 ]. This bee product is obtained from drone larvae collected from the bee family in the spring or early summer, according to the authors of [ 5 , 6 ]. Although the main role of drones is to participate in the mating flight during which the queen is inseminated, a certain percentage of drones (5–10% of the adult bee colony population) is present in the hive throughout the beekeeping season [ 6 ].…”

Drone brood is a little-known and poorly studied bee product used and valued in the treatment of many diseases, including male infertility and women’s menopausal disorders. The aim of this study was to evaluate the antioxidant activity of drone brood depending on the stage of larval development and the method of preservation. Aqueous and ethanolic homogenate extracts of drone brood were assayed for antioxidant activity (with the DPPH, FRAP, and ABTS methods), polyphenol, and flavonoid content. The extracts’ polyphenolic profiles were compared by the HPTLC method. Drone brood has been shown to be more active in the earlier stages of development (between days 7–11), with a decline in antioxidant activity in the later period (by the 14th day). The freeze-drying process did not cause significant changes in the antioxidant activity of brood preparations converted to dry mass. Based on the higher activity of the aqueous compared to 70% ethanolic extracts, it was shown that the dominant fraction of brood consisted of hydrophilic antioxidants. The results obtained with different methods were highly correlated, excluding those from the ABTS assay. The HPTLC method showed that the polyphenol fraction of drone brood homogenate consisted mainly of phenolic acids and flavonoids. It was shown that drone brood has valuable antioxidant properties that can be compared with royal jelly.

“…The use of various biologically active substances to synchronize estrus and the onset of farrowing is the best method to reduce the cost of insemination and receiving offspring. In today's conditions, the leading role in the nutrition and normalization of sexual function in pigs belongs to the use of complex biologically active additives, among which an important nutrient diet of homogenate of drone larvae (HDL), also known as drone brood homogenate (DBH) [2][3][4].…”
Background: With modern requirements for housing agricultural animals particularly pigs, the manifestation of normal physiological functions significantly changes, especially reproductive one, which is manifested in an insufficiently expressed sexual cycle, reduced resistance due to technological stress. There is a need to develop effective reproductive biotechnologies in pig using organic stimulants of entomological origin, among which a significant place is given to the homogenate of drone larvae (HDL).

Відомо, що за різноманітністю вітамінного складу гомогенат займає перше місце серед усіх продуктів бджільництва, випереджаючи навіть маточне молочко [2][3][4]. Дослідження віт чизняних науковців довели цінність продуктів бджільництва та препаратів на їхній основі, які проявляють різнобічну фармакологічну активність [5][6][7].…”

“…Одним із пріоритетних шляхів розвитку сучасної фармації є розробка твердих лікарських форм на основі речовин природного походження, які характеризуються достатньою ефективністю та безпечністю в застосуванні, а тому цікавим із погляду технології таблетованих форм є трутневий гомогенат у вигляді ліофілізованого порошку, якому притаманний широкий спектр фармакологічної активності [2][3][4].…”
Мета роботи. Вивчення впливу допоміжних речовин (ДР) на фармако-технологічні показники порошкових мас та таблеток на основі ліофілізованого порошку трутневого гомогенату з метою розробки складу таблеток.
Матеріали і методи. Активний фармацевтичний інгредієнт – ліофілізований порошок трутневого гомогенату, а також ДР, які розділені у 5 груп за функціональним призначенням. Таблетки отримували методом прямого пресування. Дослідження впливу ДР на фармако-технологічні показники порошкових мас та таблеток, проводили методами, регламентованими ДФУ.
Результати й обговорення. Дослідження проведені на основі п’ятифакторного експерименту на підставі гіпер-греко-латинського квадрату 5х5. Вивчено вплив ДР різних груп, а саме, зразків мікрокристалічної целюлози (МКЦ), наповнювачів на основі цукрів, розпушувачів, ковзних (регуляторів вологи) та змащувальних речовин на процес пресування таблеток із ліофілізованим порошком трутневого гомогенату. Результати дослідження показують, що на насипну густину порошкових мас, кут природного укосу, процес пресування, середню масу та однорідність маси таблеток найбільше впливають ковзні речовини (регулятори вологи). Розпушуючі речовини є визначальними по впливу на час розпадання таблеток.
Для прийняття рішення про вибір оптимальних ДР використано узагальнені показники – функції бажаності та корисності.
Висновок. Вивчено вплив 25-ти ДР на фармако-технологічні показники порошкових мас та таблеток з ліофілізованим порошком трутневого гомогенату. За сукупністю вивчених показників відібрано кращі поєднання ДР з метою подальшого вивчення їх впливу: Neusilin US 2, Neusilin UFL 2, кальцію фосфат двоосновний (фактор D); натрію крохмальгліколят і натрію карбоксиметилкрохмаль (фактор С); натрію лаурилсульфат і кальцію стеарат (фактор Е); Prosolv SMCC 90 та МКЦ 102 (фактор А); Ludipress та Emdex dextrates (фактор В).
