[Chemical constituents of n-BuOH extract from Phyllanthus matsumurae]
Objective:
To study the chemical constituents of n-BuOH extract from Phyllanthus matsumurae.
Methods:
Column chromatography was used for the isolation and purification. Spectroscopic methods including H-NMR, 13C-NMR and MS were used for the identification of structures.
Results:
Six compounds were isolated from the n-BuOH extract of 75% alcohol extract of the whole plant and identified as ellagic acid (1), phyllanthuspermin B (2), phyllanthuspermin C (3), xanthoxylin (4), hesperetin-7-O-[6-O-(alpha-L-rhamnopy ranosyl)] -beta-D-glucopyranoside (5) and 4-O-methylgallic acid (6).
Conclusion:
Compounds 2 - 6 are obtained from this plant for the first time.

Structure and Nomenclature of Alcohols and Phenols
Alcohols are one of the most important functional groups in organic chemistry. The name of alcohol comes from the hydrocarbon from which it is derived. Alcohols are organic molecules containing the functional hydroxyl or –OH group directly bonded to carbon. Phenols have an OH group directly attached to a benzene ring. While alcohols are colorless, phenol is a white crystalline compound with a characteristic "hospital smell" odor.

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.
