Phytochemistry and biology of Loranthus parasiticus Merr, a commonly used herbal medicine.[Pubmed:
24467533]
Loranthus parasiticus Merr (L. parasiticus) is a member of Loranthaceae family and is an important medicinal plant with a long history of Chinese traditional use. L. parasiticus, also known as Sang Ji Sheng (in Chinese), benalu teh (in Malay) and baso-kisei (in Japanese), is a semiparasitic plant, which is mostly distributed in the southern and southwestern regions of China.
METHODS AND RESULTS:
This review aims to provide a comprehensive overview of the ethnomedicinal use, phytochemistry and pharmacological activity of L. parasiticus and to highlight the needs for further investigation and greater global development of the plant's medicinal properties. To date, pharmacological studies have demonstrated significant biological activities, which support the traditional use of the plant as a neuroprotective, tranquilizing, anticancer, immunomodulatory, antiviral, diuretic and hypotensive agent. In addition, studies have identified antioxidative, antimutagenic, antiviral, antihepatotoxic and antinephrotoxic activity. The key bioactive constituents in L. parasiticus include coriaria lactone comprised of sesquiterpene lactones: coriamyrtin, tutin, Corianin, and coriatin. In addition, two proanthocyanidins, namely, AC trimer and (+)-catechin, have been recently discovered as novel to L. parasiticus.
CONCLUSIONS:
L. parasiticus usefulness as a medicinal plant with current widespread traditional use warrants further research, clinical trials and product development to fully exploit its medicinal value.

The Preliminary Study on Pesticidal Activity of Main Components in Coriaria Lactone.[Reference:
WebLink]
METHODS AND RESULTS:
Toxic symptom and contact poisoning activity of tutin,coriatin and Corianin were observed on the larvae of Mythimna separata with 3,4,5and 6instars by leaf disk method and dripping method.The results showed that the poisoning symptoms for tutin included slow in action,coma,recovery,paralysis,and dehydration on body surface,but the symptoms did not appear by using coriatin and Corianin.After treated by different proportions(1∶3,1∶1,3∶1)of tutin and coriatin,larvae with 3,4,5instars demonstrated the symptom of coma with various degrees,and the largest number of coma was 4instars,and the coma disappeared in 6instars.Different proportions of tutin and Corianin caused a decreased number of coma symptom in the larvae with 3,and 4instars,and partial coma in 6instars.Direct dripping different concentrations of tuin to each instars insect demonstrated poisoning actions,concentration 1.00mg·mL-1 exhibited the strongest poisoning effect.Different ratios of tuin and coriatin,tuin and Corianin on armyworm had significant influence on appetite and cumulative mortality rates,along with the increase of coriatin and Corianin, the impact on armyworm food intake and cumulative mortality was more significant.
CONCLUSIONS:
It was preliminarily concluded that coriatin and Corianin demonstrated synergistic effect to insecticidal activity of tutin againstarmyworm.
