POKUSY S PESTOVANÍM ĄUBOVNÍKA BODKOVANÉHO (HYPERICUM PERFORATUM L.) V BRATISLAVE
- Katedra farmakognózie a botaniky Farmaceutickej fakulty Univerzity Komenského, Bratislava
V maloparcelových pokusoch sa pestoval µubovník bodkovaný (Hypericum perforatum L. var. angustifolium DC) na µahkej pôde a na slnečnej lokalite v Bratislave. V 1. roku vegetácie sa vňa» nezbierala. Zber sa robil v 2. a 3. roku vegetácie, neskôr rastliny vyhynuli. V priebehu vegetačného roka bolo moľné urobi» spravidla tri zbery, pričom I. zber sa robil tesne pred kvetom alebo vo fáze nástupu kvitnutia a zostrihali sa len zakvitnuté vrcholové časti. Úroda suchej vňate kolísala v závislosti od vegetačného roka, podmienok stanovią»a, veku rastlín a termínu I. zberu. Z dvojročného porastu sa získala celoročná úroda 8,12-14,87 kg.10 m-2 a z trojročného porastu okolo 8 kg. 10 m-2 suchej vňate. Obsah hypericínu v získanej droge Hyperici herba kolísal od 0,06 do 0,13% a 60 % etanolom sa extrahovalo 21,7-27,9 % látok.

Experiments with the Cultivation of Hypericum perforatum L. in Bratislava
Experiments in small plots were performed to cultivate Hypericum perforatum L. var. angustifolium DC on light soil and at a sunny location in Bratislava. In the 1st year of vegetation the herb was notharvested. Harvests were made in the 2 nd and 3 rd years of vegetation and later plants died. In the course of the vegetation year it was possible to carry out three harvests on the rule. The 1st one was made just prior to blooming or at the stage of the onset of blooming, and only the blooming top parts were collected. The yield of the dry tops varied in dependence on the vegetation year, conditions ofthe location, age of the plants, and the date of the 1st harvest. From the two-years old plants, a whole-year yield of 8.12-14.87 kg.10 m-2 of dry tops and from the three-years old plants, 8 kg. 10 m-2, was obtained. The content of hypericin varied from 0.06 to 0.13 %, and 60% ethanol extracted 21.7-27,9 % of substances.
