ABSTRACT
Objective:To investigate the diuretic and renal effects of Silybum marianum L. and Cistus ladaniferus L. in normal rats.Methods:Four groups of rats were used in each experiment. The first group received water, the second group received Cistus ladaniferus L. extract (100 mg/kg b.wt), the third group received Silybum marianum L. extract (100 mg/kg b.wt), and the fourth group received furosemide (10 mg/kg b.wt). Variables including urine volume, plasma and urine sodium, potassium and creatinine, and creatinine clearance were measured. Two experiments were conducted. A single dose of each intervention was used and the variables were measured during 24 h, and the interventions were given daily for a total of 8 d and the variables were measured during various intervals.Results:The single dose of each plant extract increased urine volume at all-time intervals and increased urine sodium and potassium excretion without affecting plasma sodium and potassium (P<0.05). On the day 8 after daily administration, the plant extracts induced a significant diuresis and natriuresis without affecting serum electrolytes (P<0.05), while furosemide caused hypokalemia. Both plant extracts significantly increased creatinine clearance (P<0.05).Conclusions:Silybum marianum L. and Cistus ladaniferus L. increase creatinine clearance and have a significant diuretic effect without affecting serum electrolytes. Silybum marianum L. is more potent than furosemide or Cistus ladaniferus L.

ABSTRACT
To establish the suspension culture system of Silybum marianum cell and study the effects of different factors on silybin content. Orthogonal test was adopted to determine S. marianum cell suspension culture system and HPLC to silybin content.. The best growth cycle of cell suspension culture was defined when cultured in liquid MS medium with 6-BA 1.5 mg/L + NAA 1.0 mg/L + ZT 1.5 mg/L, light 12 h/d, pH value = 7, revolution = 110 r/min. The effects of salicylic acid, chitosan, and sodium nitroprusside on cell suspension culture were investigated. When the concentration of three impact factors were 0.05, 3, and 1 μ g/L, respectively, the growth amount of S. marianum cell reached the maximum, i. e. At the same time, the silybin content also reached the maximum. The established cell suspension culture system is suitable to use for the rapid propagation of S. marianum. Chitosan and sodium nitroprusside at proper concentration are benifit to the growth of suspensious cells and accumulation of silybin.
ABSTRACT
Objective: To study the quality testing method for the seeds of Silybum marianum, so as to provide the basis for the development of testing procedures and quality grading standard for the seeds of S. marianum. Methods: Refering to "The International Seed Testing Rules" and "China Crop Seed Testing Rules" to carry out the quality testing for the seeds of S. marianum. Results: The seed cleanliness was analyzed by winnowing method; The authenticity was identified by morphological appearance compared with 1000 grain weight by 1000 grain weight determination method; The germination conditions for seed germination were washed with running tap water before 2 h, the double filter paper was used as germination bed, and the seeds were incubated at 20 ℃, 8000 lx light, counting time for 4-14 d; The viability was determined by electrical conductivity method. Conclusion: The method is simple and reliable to the quality testing for the seeds of S. marianum.
ABSTRACT
Objective: To investigate the effects of exogenous nitric oxide (NO) on the physiology of the seed germination and seedling growth of Silybum marianum under NaCl stress. Methods: The seeds of S. marianum were treated by sodium nitro prusside (SNP) at the concentration of 0.05-0.60 mmol/L under 0.7% NaCl stress. Some physiological indexes were measured, such as germination energy, germination rate, germination index, and vigor index of the seeds, and contents of malondialdehyde (MDA), photosynthetic pigment, osmosis substances, and the activities of the protective enzymes in leaves. Results: The seed germination and seedling growth of S. marianum were obviously inhibited under NaCl stress. Soaking seeds with 0.05-0.60 mmol/L SNP could alleviate the damage of NaCl stress. Under this treatment, the contents of photosynthetic pigment (including chlorophyll a, chlorophyll b, total chlorophyll, and carotinoid) and osmosis substances (including soluble sugar, soluble protein, and proline), and the activities of protective enzymes (including SOD, POD, and CAT) in the leaves were significantly increased, while the MDA content in the leaves was decreased. Conclusion: Soaking seeds with 0.05-0.60 mmol/L SNP could promote the salt resistance of the seeds and seedlings of S. marianum. The different cultivars of S. marianum differ in the sensitivity to SNP. The optimal concentration of SNP for the seed soaking of S. marianum with white and black skins is 0.10 and 0.40 mmol/L, respectively.
