1State Key Laboratory of Phytochemistry and Plant Resources in West China, Kunming Institute of Botany, Chinese Academy of Sciences, Kunming 650204, China.
Aim:
To investigate the chemical constituents of Allophylus longipes.
Methods:
Compounds were isolated and purified by various chromatographic techniques and their structures were elucidated by physicochemical characteristics and spectral data.
Results:
Twenty-five compounds were isolated and identified as cycloart-24-en-3β, 26-diol (1), 3-oxotrirucalla-7, 24-dien-21-oic acid (2), zizyberenalic acid (3), colubrinic acid (4), ent-4(15)-eudesmene-1β, 6α-diol (5), 4(15)-eudesmene-1β, 8α-diol (6), 4(15)-eudesmene-1β, 5α-diol (7), methyl asterrate (8), betulin (9), betulinic aldehyde (10), betulinic acid (11), 3β-hydroxy-5α, 8α-epidioxyergosta-6, 22-dien (12), 3-oxo-19α-hydroxyurs-12-en-28-oic acid (13), ursolic acid (14), scopoletin (15), fraxidin (16), cleomiscosin A (17), 4-hydroxy-3-methoxybenzaldehyde (18), 4-hydroxy-3-methoxycinnamaldehyde (19), 2',6'-dihydroxy-4'-methoxyacetophenone (20), p-(aminoalkyl)-benzoic acid (21), 4-hydroxy-3-methoxybenzoic acid (22), 1-O-p-coumaroylglucose (23), β-sitosterol (24), and poriferast-5-ene-3β, 4β-diol (25).
Conclusion:
All the compounds were isolated from Allophylus longipes for the first time.

Basicity of Aliphatic Amines
To measure the basicity of amines, two conventions are generally used. The first defines Kb as the basicity constant for the deprotonation reaction of water by the amine, as presented in Figure 1. Conventionally, lower Kb indicates higher...
Structure and Physical Properties of Alkynes
In nature, compounds containing both carbon and hydrogen are known as "hydrocarbons". Aliphatic hydrocarbons are compounds whose molecules contain saturated single bonds (i.e., alkanes) or unsaturated double or triple bonds. Alkenes contain carbon–carbon double bonds and have a structural formula CnH2n. Unsaturated hydrocarbons containing carbon–carbon triple bonds are called "alkynes" and are structurally represented by the formula CnH2n-2.
The simplest alkyne is ethyne, or...
Allosteric Proteins-ATCase
Aspartate transcarbamoylase (ATCase) is a cytosolic enzyme that catalyzes the condensation of L-aspartate and carbamoyl phosphate to N-carbamoyl-L-aspartate. This reaction is the first step in pyrimidine biosynthesis. UTP and CTP, the end products of the pyrimidine synthesis pathway,...
