Abstract:
1,4,13-Trihydroxy-eudesm-11(12)-ene, a new eudesmane derivative (3), (9E)-8,11,12-trihydroxyoctadecenoic acid methyl ester, a new fatty acid ester (2) and tianshic acid (1) were obtained from the stems of Sambucus williamsii. Their structures were elucidated by physiochemical properties and spectroscopic analysis. Both compounds 1 and 2 showed stimulating effects on alkaline phosphatase activity of the osteoblastic UMR106 cell about 1.5 fold at 30 mumol/l while they had no effects on cell proliferation.

Ethers from Alcohols: Alcohol Dehydration and Williamson Ether Synthesis
Ethers can be prepared from organic compounds by various methods. Some of them are discussed below,
Preparation of Ethers by Alcohol Dehydration
In this method, in the presence of protic acids, alcohol dehydrates to produce alkenes and ethers under different conditions. For example, in the presence of sulphuric acid, dehydration of ethanol at 413 K yields ethoxyethane, whereas it yields ethene at 443 K.
