Quality Change of Citri Reticulatae Pericarpium (Pericarps of 'Chachi') During Storage and Its Sex-Based In Vitro Digestive Performance.

Citri Reticulatae Pericarpium (CRP), particularly including the pericarp of 'Chachi' (GCP), has been widely used as a food, a dietary supplement, and traditional Chinese medicine. Despite the widespread use of traditional foods, there is limited evidence regarding the precise relationships between storage conditions, aging duration, and the digestive performance of CRP. In this study, the aim was to investigate the impact of the storage conditions on the quality of aged GCP during shelf life and to evaluate the subsequent digestive performance of corresponding GCP decoctions.

1-Meth-oxy-2-methyl-1H-benzo[f]indole-3-carbonitrile.

Apart from the methyl group of the meth-oxy fragment, the title compound, C(15)H(12)N(2)O, is almost planar (r.m.s.

2-mesitylacetic Acid.

In the title compound, C(11)H(14)O(2), the dihedral angle between the CCOO carboxyl unit and the benzene ring is 85.37 (7)°. In the crystal, the mol-ecules are linked into inversion dimers by pairs of O-H⋯O hydrogen bonds.

2-Methyl-3-p-tolyl-3H-benzo[e]indole-1-carbonitrile.

In the title compound, C(21)H(16)N(2), the dihedral angle between the benzoindole and tosyl ring systems is 71.99 (7)°. In the crystal, mol-ecules are linked into centrosymmetric dimers by pairs of C-H⋯N hydrogen bonds, generating R(2) (2)(16) loops.

2-(2,4-Dichloro-phen-yl)acetic acid.

In the title compound, C(8)H(6)Cl(2)O(2), the dihedral angle between the C-C(=O)-OH carboxyl unit and the benzene ring is 70.70 (4)°. In the crystal, mol-ecules are linked into inversion dimers by pairs of O-H⋯O hydrogen bonds.
