  • Silymarin is the standardized extract from Silybum marianum which consists mainly of flavonoids and polyphenols. It is highly regarded for its hepatoprotective ability. Silybin B is a flavonolignan and one of the active components of silymarin. The content of silybin B in various parts of S. marianum was analyzed by HPLC-UV. Results show that the extract of seeds contain the highest amount of silybin B (7.434 mg/g DW). The petioles of S. marianum showed a low content of silybin B. This study revealed that seeds of S. marianum contain high amount of silybin B and could be a good source of the compound.

  • This study was conducted to evaluate the effects of dietary supplementation of Silybum marianum seed (SMS) extract on the growth performance, nutrient digestibility, fecal noxious gas emission, and hematology parameters in weaned piglets. A total of 120, 21-day-old weaned piglets ([Yorkshire × Landrace] × Duroc) were randomly assigned to 3 groups based on the average initial body weight (6.46 ± 0.45 kg). There were 8 replicate pens per treatment and 5 pigs (mixed sex) per pen. The experimental period was 42 days. Dietary groups included a basal diet, and a basal diet supplemented with 0.05% or 0.10% SMS extract. Feeding weaned piglets with SMS extract containing diet significantly increased average daily gain and average daily feed intake. Additionally, the supplementation of SMS extract had no significant effects on nutrient digestibility, serum hematology, and fecal noxious gas emission parameters. We considered that the supplementation of SMS extract had positive effects on the voluntary feed intake in weaned piglets, thus improving growth performance.

  • Silymarin is a standardized extract obtained from the seeds and fruits of Silybum marianum L., or commonly called milk thistle, a member of Carduus marianum family that contains mix of flavonolignans. Some epidemiological and preclinical studies revealed that S. marianum L. has been used for herbal remedies for centuries for its pharmacological activity. In this review, pharmacological studies in vitro and in vivo of silymarin are discussed thoroughly stressing on antioxidant, antimicrobial, antiviral, and anti-carcinogenic aspects of silymarin. In addition, the protective influences of silymarin on some organs such as heart, liver, bone, and neuron tissue are reviewed as well. This review would be useful for further study regarding the potential of natural plant, notably silymarin, and its therapeutic potential in the prevention and treatment of diseases.

  • This study was undertaken to evaluate as antioxidant activity against lipid peroxidation. Silymarin and silybin extracted from Silybum marianum were successively purified wit solvent fractionation by silica gel column chromatography. These isoflavonoid inhibited superoxide anion production in the xanthine oxidase system. In the rat liver microsomes, silymarin or silybin rapidly inhibited lipid peroxidation which was initiated enzymatically by reduced nicotinamide adenine dinucleotide phosphate(NADPH) or non-enzymatically by ascorbic acid or Fenton's reagent (H2O2+Fe2+). Mitochondrial lipid peroxidation was also inhibited by silymarin and silybin. silymarin and silybin inhibited on terminating radical chain reaction during lipid peroxidation in the enzymatic system of microsomes or in the linoleic acid hydroperoxide induced peroxidation system.

  • This study was performed to evaluate the antioxidant activity of silymarin against human low density lipoproteins(LDL) oxidation. Silymarin extracted from Silybum marianum was successively purified with solvent fractionation and followed by silica gel column chromatography. The active substances were separated by HPLC and the isolated active substances, silymarin were identified by IR, NMR, GC-MS as silymarin. Silymarin inhibited at the 5 $\mu$M Cu2+-mediated oxidation of human low density lipoprotein (LDL) in a dose dependent manner. Silymarin completely inhibited LDL oxidation at 50 $\mu\textrm{g}$/$m\ell$ concentration. These findings suggest that silymarin may protect LDL against oxidation in atherosclerotic lessions.

  • This study was initiated to antioxidant activity of silybin on oxidation of human low density lipoproteins(LDL). Siltbin was extracted from Silybum marianum by the combination of fractionation and it was futher purified by silica gel column chromatography, and isolated active substances were identified silybin by IR, NMR and GC-MS. siltbin inhibited the ozidation of human low density lipoprotein(LDL) mediated by 5$^{\mu}$m CU $^{2+}$ ion in a dose dependent manner. LDL oxidation by congugated dines formation was completely inhibited by silybin at a concentration of 5$^{\mu}$M. The results provide a possibility that silybin might protect LDL against oxidation in atherosclerotic lessions.

  • A growing body of evidence supports lipid peroxidation as having a role in the pathogenesis of liver disease. Although the probable cause of damage to human hepatocytes may be multifactorial, free radicals have been implicated in a variety of liver diseases, particularly in the presence of iron overload and toxic substances such as ethanol. Consequently, antioxidants, particularly those of plant origin such as flavonoids, may help to reduce the risk of developing these diseases. Silybum (S.) marianum, a medicinal plant widely used in traditional European medicine for the treatment of liver disorders, was evaluated for antioxidant activity. Thin layer chromatography and High Performance Liquid Chromatography analyses of crude extract of the plant confirmed the presence of a number of flavonoids reported in the literature. The antioxidant activity of these flavonoids was measured through inhibition of lipid peroxidation and 1, 1-diphenyl-2- picrylhydrazyl radical scavenging. The crude plant extract showed marked antioxidant activity in both assays. These results suggest that S. marianum contains flavonoids with antioxidant activity, capable of inhibiting or scavenging free radicals, thus supporting its traditional use as a hepatoprotective agent.

  • Ultraviolet rays (UV) cause photoaging by inducing skin photodamages such as erythema and sunburn. Silymarin is a mixture of antioxidant polyphenols extracted from Silybum marianum fruit (S. m), which is known as milk thistle. It is known to protect skin tissues from UV treatment and antioxidant effects. In this study, we aimed to identify the photoprotective effects of S. m extract, which has silymarin in the epidermis layer of the skin. We found that the extract can function as a UV filter, so it can reduce DNA damage by UV treatment. Especially, we found that, in the stratum corneum, the extract can suppress the protein carbonylarion and DNA damages caused by suberythemal dose of UV treatment which does not induce erythema in the skin. UV treatment also increased protein carbonylation levels in the stratum corneum by oxidation, but it was prevented by applying the extract. The extract can absorb UV with minimal phototoxicity. Together, our study suggests that S. m extract can be used as a photo-protective ingredient to avoid photoaging of the skin.

  • Herbal plants or traditional Oriental medicine have been considered as a potential resource of new drug development worldwide. However, traditional Korean medicine has given little effort to the field of new drug development. This study reports on a plant-derived hepatotherapeutic drug, silymarin, which has been popularly used in many countries. It was discovered as an active compound from Silybum marianum (milk thistle) which has been known as a medicinal plant having hepatoprotective properties in both European and Asian countries. While it has been used as an herbal prescription in Asia, its active compounds or scientific mechanisms were intensively studied in Europe. Currently, silymarin is one of the most powerful herbal extracts in the world, and its usage is being expanded to many other medical purposes. This report would be helpful for providing an informative example of herbal-derived drug development to Oriental doctors or scientists in the Oriental medicinal field.
