In the present study, we established receptor binding assays to evaluate the water extracts of ten central nervous system (CNS)-active Chinese herbal drugs. These ten herbal drugs are Chaihu (Radix Bupleuri), Chuanxiong (Rhizoma Chuanxiong), Danggui (Radix Angelicae sinensis), Danshen (Radix Salviae miltiorrhizae), Duhuo (Radix Angelicae pubescentis), Hangqin (Radix Scutellariae), Qinjiao (Radix Gentianae macrophyllae), Shengma (Rhizoma Cimicifugae), Suanzaoren (Semen Zizphi spinose), and Yangjihua (Flos Daturae). The results indicated that these water extracts contained the principles acting on the dopamine (D1 & D2), muscarinice acetylcholine (M1), or 5-HT (5-HT1A & 5-HT2) receptors, or the benzodiazepine and the gamma-amino-n-butyric acid (GABA) binding sites of GABAA receptors as determined by receptor binding assays. The receptors or binding sites which predominantly acted by each water extract are listed as follows: Chaihu: D2, 5-HT1A, GABA; Chuanxiong: GABA, 5-HT1A; Danggui: GABA, 5-HT1A; Danshen: BDZ; Duhuo: GABA, 5-HT1A, D2, D1; Hangqin: BDZ, D1, 5-HT1A; Qinjiao: GABA, BDZ, 5-HT1A, D2; Shengma: 5-HT1A; Suanzaoren: 5-HT1A, 5-HT2, GABA; Yangjihua: M1, 5-HT1A, 5-HT2. These results provided evidence to explain the CNS effects of these herbal drugs at the receptor level. Furthermore, these results provided information to direct the isolation and purification of receptor-interactive compounds from these herbal drugs.
