STANDARDISED STEROID SAPONIN MIXTURE, METHOD OF ITS OBTAINING AND APPLICATION
FIELD OF THE INVENTION
The present invention relates to a standardised steroid saponin mixture obtained from the epigeous part of Tribulus terrestris L for application in the synthesis of drugs exerting the already known aphrodisiac effect in addition to drugs with new indications. The invention pertains also to the method of preparing of a standardised steroid saponin mixture obtained from the epigeous part of Tribulus terrestris L
BACKGROUND OF THE INVENTION A method of isolating a standardised steroid saponin mixture obtained from the epigeous part of Tribulus terrestris L. (BG Patent 52085) is know to exist, the said method consisting in subjecting the plant material to extraction using an up to 70 per cent solution of low alcohol, ethanol in particular, then chloroform treatment and extraction from the vvater solution using vvater-saturated n-butanol, follovved by concentration of the butanol extract up to 1/8th of the volume, after vvhich the residue thus obtained is separated and dried, while the residues from the mother liquors are water-dissolved and then added directly to the chloroform-treated vvater solution. According to the examples described, a standardised mixture is thus obtained, the said mixture containing 50 to 55 per cent of furostanol saponins, calculated on the basis of protodioscin. Harvest is betvveen 1.7 to 2 per cent depending on the saponin content in the plant material.
The problem that the present invention has solved is the extraction from the epigeous part of Tribulus terrestris L. of a substance containing a high Ievel of furostanol saponins, vvhich can be used to prepare nevv drugs vvith nevv indications. 2
DETAILED DESCRIPTION OF THE INVENTION
According to the present invention, the problem has been solved by obtaining a standardised steroid saponin mixture containing 80 per cent of furostanol saponins. The method of preparation consists in subjecting the ground plant material to extraction using aqueous methanol solvent with a water/methanol ratio ranging from 1:1 to 1:99 at a temperature from 52 to 55°C. The extract is then treated with active carbon and after filtration is vacuum concentrated until methanol is fully removed. The aqueous concentrate is subsequently subjected to extraction with methylene chloride. Methylene chloride is then distilled off and regenerated for further use in the method. The purified aqueous solution is acidified with hydrochloric acid up to pH 4 and is subjected to extraction with vvater-saturated n-butanol by the known method. Butanol extracts are then vvashed with a sodium chloride solution and vacuum concentrated to obtain a dry residue vvhich is dissolved in a low alcohol. Thereafter, the concentrate is either added drop-by-drop to acetone and left at a temperature of 10-15° C for about 24 hours, then filtered, vvashed with acetone and dried, or vvashed with a 0.5-1.5-per cent sodium hydroxide solution and, after separating the two layers, the butanol layer is vvashed vvith vvater to reach pH = 7, then the butanol extracts are vacuum concentrated until the organic solvent is fully removed and the aqueous solution is dried. A soft and light bright yellow povvder containing more than 80 percent of furostanol saponins is thus obtained. Harvest from air-dried plant material is about 3 per cent.
This new product containing more than 80 per cent of furostanol saponins can be used to prepare new drugs exerting an immunomodulating and/or immunostimulating effect.
EXAMPLES EXAMPLE 1
One tonne of ground plant material is subjected to extraction using a 70- per cent methanol aqueous solution at 50° C until exhaustion. The extract is dravvn off, then active carbon is added thereto. The resultant is passed 3 3 LV 13366 through a filter press. The aqueous concentrate thus obtained is subjected to a triple extraction with methylene chloride in a ratio of 1:2, 1:1, and 1:1 respectively. The organic solvent is distilled of and regenerated, vvhile cube residue is disposed of. The purified aqueous extract is acidified with hydrochloric acid up to pH 4 and subjected to an eightfold extraction with water n-butanol in a ratio of 1:1. Butanol extracts are washed with a 5-per cent sodium chloride solution and the concentrated until a dry residue is obtained under vacuum at 60° C and then dissolved into methanol. The mixture is slowly dropped into acetone, left at a temperature of 10° C for 20 hours and finally Nutch-filtered, washed with acetone and dried. A light yellow powder containing 85 percent of furostanol saponins is obtained as a result. Harvest is 3 per cent from air-dried plant material.
The product analysis is performed on the basis of protodioscin. (R. Gyulemetova, M. Tomova, M. Simova, T. Pangarova, Pharmazie, 37, H.4 1982). EXAMPLE2

RESULTS FROM TESTING OF THE STEROID MIXTURE ACCORDING TO THE INVENTION ON THE IMMUNE SYSTEM OF EXPERIMENTAL ANIMALS
Material and method
Plant material
The substance containing furostanol saponins (FS) was isolated from Tribulus terrestris L (Zigophyllaceae) according to the present invention. Lyophilised FS were stored at 4°C away from light and moisture. The solution used the experiments was prepared ex tempore on the basis of physiologic solution.
Experimental animals and protocol
Male ICR mice (average body vveight from 18 to 20 g) were given various oral doses of FS, according to the description shown in Table 1.
Experimental infection
Experimental infection was caused in a mouse by subcutaneous inoculation of 25 to 30 bacterial celis from an 18-hour agar Kl. Pneumonae culture (strain No 52145, Pasteur Institute, Paris). Contamination dose was chosen after running preliminary experiments aimed at obtaining a 50-per cent survival rāte. The infection was followed up for eight days, taking account of the subject’s general condition, mortality rāte (percentage), survival rāte and average survival time (ASTa in days). The protective effect of FS was evaluated along the increase in survival rātes and average survival times calculated as differences betvveen experimental groups and Controls.
In-vitro antibacterial inhibition tēst
The sensitivity of Kl. Pneumoniae celi to FS was determined using an adapted version of the Bauer method (4). Petri dishes (100 mm) containing agar were inoculated with 0.2 ml of bacterial suspension (10 cells/ml). VVells (10 mm) were made and filled with 0.2 ml of a FS solution of various concentration. Inhibition areas were measured after incubation for 24 hours at 5 5 LV 13366 37°C. Keflin was used as a positive control (Lilly, USA), in minimum inhibition concentrations of 0.150 mg/ml.
Phagocytic and microbicidal activity of alveolar macrophages aMa
Alveolar Ma were obtained through in situ lung lavage by injecting and drawing a 0.1 -1.0 ml TCM 199 solution containing 20 mM HEPES, 100 U/ml of penicillin and 0.1 mg/ml of streptomycin (Flaw Lab., UK) plus 3 U/ml of heparin (G. Richter, Hungary). The average number of washed aMa from each group was determined and the celis were then placed on incubation plates (BDSL, Scottland) in a concentration of 3 x 10 cells/ml to assess their phagocytic and microbicidal activity using a H3-thymidine radiometric method.(5)
Results
Anti-infectious protective effect
The results thus obtained show that FS affect the course and outcome of an experimental Kl. Pneumonia-induced infection in mice. In treated animals, mortality rāte reached a maximum of 30 to 40 per cent by the 4^-5^ day from infection (Figurē 1). The peak in mortality rāte in the Controls was considerably higher (70 to 80 percent) and was observed on the 2nd - 3rd day from infection. To summarise, the administration of FS leads to reduced severity of the clinical picture, lower mortality rāte, and prolonged lifetime in treated animals.
The anti-infectious effect of FS variēs according to dosage and administration schedules (Table 1). The highest dose administrated (625.0 mg/kg) shovved the strongest protective effect in ali 10-day administration schedules, starting 35, 25 or 15 day before infection; the peak of the effect was observed where the last FS dose was administered on the 15th day before infection.
In contrast to the marked in-vivo activity, FS do not exhibit in-vitro antibacterial activity. A solution of FS in physiological serum at concentrations of 0.01, 0.025, 0.05, 0.1, 2.0, 5.0, 10.0, 25.0, 50.0, 100.0, 250.0 and 500.0 mg/ml did not suppress Kl. Pneumoniae grovvth, unlike the marked suppression obsen/ed in the Keflin group, within a mean area of 21.5 ± 1.0 mm. 6
Stimulation ofaMa
Doses of 625.0 mg/kg cause aMa to increase in number and phagocytic and microbicidal activity with a peak by the 20* day from the last application of FS (Table 2).
Discussion
Unlike other saponins (3), FS do not exert a bactericide effect. FS influence the main effector mechanisms of celi and humoral immunity thus granting a marked protection from infection. The optimum dose of 625.0 mg/kg administered over a sequence of 10 days is very close to the schedule (6) applied in humāns. The strongest protective effect obtained with the schedule vvhere the time gap betvveen the last application of FS and infection is 15 days can be explained with the dynamics of aMa activation. The maximum increase in their functional activity is observed by the 20* day vvhich coincides with the acute phase of the infection (day 3 to 5). The great number of aMa with an increased phagocytic and microbicidal capacity prevent aggravation of the infection and reduce mortality rāte, thus simultaneously increasing survival rāte. Obviously, the protective effect of FS is fully achieved only after a given period of time necessary for the immune system to react. FS activate aMa vvhich play a significant role in the anti-bacterial protection of the lung, in particular in managing infections caused by opportunistic pathogens such as Kl. Pneumonae (6).
