[Methods] Ultrasound assisted method was used. [Results] Water bath temperature had little impact on green pigment, and Al^(3+), Cu^(2+), Mg^(2+) and Zn^(2+) in metal ions greatly affected green pigment, while Fe^(3+) had very little impact on the stability of green pigment. pH did not basically affect green pigment of A. lappa L. [Conclusions] The extraction rate and stability of green pigment from leaves of A. lappa L. were higher, and it was one of materials suitable for extracting green pigment.展开更多

[Methods] The wet digestion and technique of inductively coupled plasma emission spectrometry(ICP-OES) were used. [Results] 20 kinds of inorganic elements in the samples of A. lappa L. roots contained rich elements essential for human beings such as K, Ca, Na, P and trace elements Cu, Fe, Zn; heavy metals Pb, As, Cu, Cd in A. lappa L. samples did not exceed the limit, and Hg was not detected in all 12 samples; heavy metals in A. lappa L. roots harvested in 12 months did not exceed the limit. [Conclusions] Compared with the roots of A. lappa L., the inorganic elements in the stems and leaves of A. lappa L. were relatively less. The samples collected from Shuimo Town in Wenchuan County of Aba Prefecture with an altitude of 920 m showed little difference from samples collected from Qiongxi Town in Hongyuan County of Aba Prefecture with an altitude of 3 505 m in 20 kinds of inorganic elements.展开更多

About 25,000 biological active compounds are reported by different scientists. Plants itself are a complete treatment bioagent. People are still using plants and their decoction for different diseases. Saussurea lappa Clarke is the member of family Compositae. This plant is famous due to its high medical importance. The plant is commonly named as Kuth root or costus and has wide use for anticancer, antiulcer, hepatoprotective, anti-viral, anticonvulsant, antiarthritic, activities. Biologically active substance of in this plant is lactone cynaropicrin, dehydrocostus, germacrene,?lappadilactone. This plant can be used to extract such bioactive compounds which can help the scientist to discover new and potential drugs. Due to such chemical composition and medicinal importance this review has been prepared for the awareness of the people to conserve their medicinal plants which can be used for potential drug discovery.展开更多
