Objective:
To study the chemical constituents of Abelmoschus esculentus.
Method:
The chemical constituents were isolated and purified by chromatography on silica gel and recrystallization. The chemical structures were elucidated on the basis of physicochemical properties and spectral data.
Result:
Fourteen compounds were isolated and identified as 6-hydroxy-stigmasta-4-en-3-one(1), 6-hydroxy-stigmasta4,22-dien-3-one(2), stigmasta-5-en-3-ol-7-one(3), stigmasta-5, 22-dien-3-ol-7-one(4), stigmast-5-en-3, 7-diol(5), stigmast-5, 22-dien-3, 7-diol(6), stigmast-4, 22-dien-3, 6-dione(7), stigmasta-4, 22-dien-3-one(8), ergosta-7, 22-dien-3-ol(9), cycloart-25-en-3,24-diol(10), lupeol(11), aurantiamide acetate (12), stigmasterol(13), hexadecanoic acid (14).
Conclusion:
Compounds 1-12 are obtained from the genus Abelmoschus plant for the first time and also from the Malvaceae for the first time.

02:29Ethers 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.
02:17Physical Properties of Ethers
An ether molecule has a net dipole moment due to the polarity of C–O bonds. Subsequently, boiling points of ethers are lower than those of alcohols of comparable molecular weight and slightly higher than those of hydrocarbons of comparable molecular weight (Table 1).
Ethers can act as hydrogen bond acceptors, making them more water-soluble than hydrocarbons, but since ethers cannot act as hydrogen bond donors, they are much less soluble in water than alcohols. Ethers are considered...
02:35Ethers from Alkenes: Alcohol Addition and Alkoxymercuration-Demercuration
Ethers can also be prepared from alkenes through acid-catalyzed addition of alcohols and alkoxymercuration–demercuration.
Preparation of Ethers by Acid-Catalyzed Addition of Alcohol to Alkenes
The acid-catalyzed addition of alcohol to an alkene involves treating the alkene with an excess of alcohol in the presence of an acid catalyst to form an ether under suitable conditions. The hydrogen will add to the less substituted carbon so that the nucleophile can attack the more substituted...
