Abstract:
[Objective] To assess the quality of Citrus grandis Osbeck. Var. tomentosa Hort. (CGO Var. TH) and Citrus grandis (L. ) Osbeck (CGO). [Methods] The macroscopic feature and microscopic structure of CGO Var. TH and CGO were compared. Their content of total flavones (TF) was determined by spectrometry, naringin content and fingerprint by high performance liquid chromatography (HPLC) and the content of rhoifolin by thin-layer chromatography (TLC). Their expectorart, anti-inflammatory and antitussive effects were observed by phenol red test, auricular swelling test and ammonia-water-induced cough method. [Results] Obvious differences such as villi in the exocarp and non-grandular hair in the stem existed in the macroscopic feature and microscopic structure of CGO Var. TH and CGO. The contents o{ total flavones and naringin in CGO Var. TH were markedly higher than that in CGO and the rhoifolin content in CGO Var. TH was ten times as much as that in CGO. Markedly difference was also found in their fingerprint. The expectorant, anti-inflammatory and antitussive effects in CGO Var. TH were better than those in CGO. [Conclusion] The quality of CGO Var. TH is much better than that of CGO.
