[Liposolubility constituents from leaves of Aquilaria sinensis]
1State Key Laboratory of Natural and Biomimetic Drugs, Department of Natural Medicines, School of Pharmaceutical Sciences, Peking University, Beijing 100191, China.
Objective:
To study the chemical constituents of the leaves of Aquilaria sinensis.
Method:
The compounds were isolated and purified by the methods of solvent extraction and chromatographic technique, and their structures were identified on the basis of the analyses of spectral data.
Result:
Eleven compounds were obtained and identified as beta-sitosterol (1), hexacosanic acid (2), cryptotanshinone (3), 2alpha-hydroxyursane (4), dihydrotanshinone I (5), tanshinone I (6), tanshinone II(A) (7), 2alpha-hydroxyursolic acid (8), p-hydroxybenzoic acid (9), hydroquinone (10), and daucosterol (11), respectively.
Conclusion:
All compounds except for compound 9 were isolated from the leaves of A. sinensis for the first time.

Factors Affecting Solubility
Solubility
A solution is a homogeneous mixture composed of a solvent, the major component, and a solute, the minor component. The physical state of a solution—solid, liquid, or gas—is typically the same as that of the solvent. Solute concentrations are often described with qualitative terms such as dilute (of relatively low concentration) and concentrated (of relatively high concentration).
In a solution, the solute particles (molecules, atoms, and/or ions)...
