Gibberellic acids were extracted into ethyl acetate at pH 2.5 and 3.0, re-extracted into buffer at pH 8.0 or pH 6.5, and re-extracted into ethyl acetate after adjusting to pH 2.5 to 3.0. Almost all of the free Gibberellic acid was obtained in the acid fraction of ethyl acetate. A portion of the gibberellic acid glucosyl esters can be extracted from the acidified aqueous phase with 1-butanol (T. Sakahashi: Plant Growth Substances 1973, Hirokawa, Tokyo, 228/1974). High concentrations of phosphate buffer can lead to incomplete recovery of nonpolar glucose esters at 8 gibberellic acids. 0 / kC Durley, R.P. Pharis: Phytochemistry 11,317 (1972), respectively. 6.5. Extreme pH values cause degradation of gibberellins. Lipids that would interfere with separation and biological methods are removed with light petroleum or diethyl ether at neutral or slightly alkaline pH prior to extraction of the gibberellins. While petroleum ether does not extract gibberellins from the buffer phase at pH 8.0, diethyl ether extracts a significant portion of the low-polar gibberellins (fc.C). Durley, R.P. Pharis: Phytochemistry 11, 317/1972 / J, Half the amount of gibberellins are glucose esters of gibberellic acids which can be destroyed by hydrolysis with inorganic acids or bases and then extracted with ethyl acetate. Compared to acidic and alkaline hydrolysis, enzymatic hydrolysis is preferred because less destructive is formed

After swelling, the bean is extracted with 4000 ml of 80% methanol in the dark at 8 ° C for 48 h. The extract is filtered and allowed to stand? in the dark at 8 ° C for 72 µl. The solid residue was re-extracted with 4000 mL of 80% methanol in the dark at 8 ° C for 72 h. Filtration gave another extract which was combined with the previous and concentrated together at 300 psi to 300 mL of solution. The lipids are removed four times by extraction with 150 ml of diethyl ether after adjustment to pH 8.0 with solid sodium bicarbonate. The aqueous phase / 440 g / was modified to pH 2.5 with 37% HCl three times extracted with 500 ml of ethyl acetate, and the obtained extract containing gibberellic acid much lazy. The aqueous phase, extracted with ethyl acetate, is extracted twice with 500 ml of 1-butanol, and the 1-butanol extract is concentrated under a pressure of 10 mbar to 56 g of syrup containing glucose esters of gibberellic acid, which is diluted with 250 ml of 80% methanol. The gibberellic acid glucose ester solution is freed from inorganic salts, organic acids and bases by deionization on a column packed with a sulfonic-functional ion exchange (Dowox 50 WX 8 0.3-0.85 mm) 50 cm long and cm in diameter and on a column packed with a functional group trimethylammonium hydroxide / Ostion AT 0809 0.315 to

Neionizovaný roztok a eluát sa spoločne zahustia pri tlaku 3 kPa na 10 ml roztoku, ktorý sa rozpustí v 100 ml 80 % metanolu. Metanolicko-vodný roztok glukózylesterov kyselin giberelových sa hydrolyzuje s 50 g ionomeniča s funkčnými sulfoskupinami /Dowex 50 W X 4 0,040 až 0,075 mm/ za miešania pri teplote 25 °C po dobu 2 h. lonomenič sa odfiltruje a premyje s 20 ml 80 % metanolu. Sfiltrovaný roztok sa odfárbí s 1,5 g aktívneho uhlia a sfiltruje po době 17 h. Odfarboný roztok sa zahustí pri tlaku 3 kPa na 3,6 g 90 % sirupu obsahujúceho 60 % kyselin giberelových a 30 % D-glukózy, ktorý sa' zriedí s 80 % metanolom na 6 % roztok kyselin giberelových; Biologická aktivita: 0,05 ml 6 % kyselin giberelových sposobilo’17O % prírastok oproti kontrole a 0,075 ml 6 % kyselin giberelových spósobilť210 % prírastok oproti kontrole^ 50 /ig kyseliny giberelovej spósobifc^OO % prírastok oproti kontrole.0.8 mm / with a length of 50 cm and a diameter of 4 cm. 2000 ml of 80% methanol are used as eluent. The non-ionized solution and the eluate are concentrated together at 10 mbar to 10 ml of a solution which is dissolved in 100 ml of 80% methanol. The methanolic-aqueous solution of glucose esters of gibberellic acids is hydrolyzed with 50 g of sulfonated ion exchanger (Dowex 50 W X 4 0.040-0.075 mm) with stirring at 25 ° C for 2 h. The ion exchanger is filtered off and washed with 20 ml of 80% methanol. The filtered solution is decolorized with 1.5 g of activated carbon and filtered after 17 h. The decarbonate solution is concentrated at 3 kPa to 3.6 g of a 90% syrup containing 60% gibberellic acid and 30% D-glucose, which is diluted with 80% methanol to a 6% gibberellic acid solution; Biological activity: 0.05 ml of 6% gibberellic acid produced a 170% increase over the control and 0.075 ml of 6% gibberellic acid caused a 210% increase over the control of ≥50 µg of gibberellic acid to give a 50% increase over the control.
Vynález móže nájsť široké použitie v polnohospodárstve a při štúdiu biochemických procesov v rastlinách· Kyselinami giberelovými sa móže rušit4 dormancia semien a spiacich pupoňov rastlín· U niektorých rastlín sa móže indukovat’ kvitnutie. Ďalej sa může kyselinami giberelovými zváčšiť velkost’ plodov.The invention can find widespread use in agriculture and in the study of biochemical processes in plants. 4 Dormancy of seeds and sleeping buds of plants can be abolished by gibberelic acids. Furthermore, the size of the fruits can be increased by gibberellic acids.
