ABSTRACT
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.

The content analysis of fatty acids in Perilla cultivars and commercial oils is conducted through gas chromatography with a flame ionization detector. Results show that Perilla cultivars, such as Deulsaem and Daesil, contain high amounts of α-linolenic acid (262.22 and 261.97 mg/g, respectively). Among commercial oils, Perilla oil contains a higher amount of α-linolenic acid (515.20 mg/g). Accordingly, α-linolenic acid is a major fatty acid of Perilla cultivars and oil. Therefore, Perilla cultivars could be used as a food supplement for nutritional and pharmaceutical purposes.
