Ten compounds were isolated from the aerial part of Solanum rostratum by means of various chromatographic techniques such as silica gel, Sephadex LH-20, ODS and preparative HPLC. Their structures were identified as dioscin (1), hypoglaucin H (2), hyperin (3), isoquercitrin (4), isorhamnetin-3-O-beta-D-galactopyranoside (5), kaempferol-3-O-beta-D-glucoside (6), smilaxchinoside A (7), 26-O-beta-D-glucopyranosyl-3beta, 20alpha,26-triol-25 (R) -delta5,22-dienofurostan-3-O-alpha-L-rhamnopyranosyl (1 --> 2) -[ alpha-L-rhamnopyranosyl (1 --> 4)] -beta-D-glucopyranoside (8), beta-sitosterol (9), and daucosterol (10), on the basis of physicochemical properties and spectroscopic data analysis. Among them ,compounds 7 and 8 were isolated from the genus Solanum for the first time, and the remaining compounds were obtained from this plant for the first time.

To study the absorptive characteristics of aqueous extracts from Salviae Miltiorrhizae Radix et Rhizoma by in vitro rat everted intestinal sac model. Three representative ingredients in aqueous extracts from Salviae Miltiorrhizae Radix et Rhizome--protocatechuic aldehyde (PAL), posmarinic acid (RA) and salvianolic acid B (SAB), were selected as the study objects. An UPLC method was established to determine and measure their cumulative absorption amount, in order to explain the absorption characteristics of ingredients in different intestinal sections. According to the experimental result, RA and SAB showed the passive absorption in ileum, which conformed to the first-order absorption rate; with low and medium doses, they showed a zero-order absorption rate in jejunum, which was reflected in the coexistence of both positive and passive absorptions; PAL showed a passive absorption manner both in ileum and jejunum. According to the experiment for absorption in different intestinal sections, RA and SAB were mainly absorbed in jejunum, while PAL was absorbed mainly in ileum. All of the three ingredients in aqueous extracts from Salviae Miltiorrhizae Radix et rhizome--PAL, RA and SAB could be absorbed in intestines, but with differences in the absorption rate and mechanism, which indicated that the intestinal absorption of aqueous extracts from Salviae Miltiorrhizae Radix et rhizome was selectivity, instead of a simple semi-permeable membrane penetration process.

Fourteen compounds were isolated by column chromatography from the ethyl acetate extract of the seeds of Brassica campestris. Their structures were elucidated by physicochemical properties and spectroscopic data analysis. The isolated compounds were respectively identified as (5Z,7E)-4, 4-dimethyl-5-acetyl-5, 7-nonadienoic acid (1), indole-3-carboxaldehyde (2), blumenol A (3), vinylsyringol (4), sinapinic acid (5), sinapic acid ethyl ester (6), protocatechuic acid (7), crinosterol (8), campesterol (9), 7-oxo-stigmasterol (10), kaempferol (11), 2,5-dihydroxybenzoic acid (12), syringic acid (13) and daucosterol (14). Compound 1 was a new compound and the other compounds were isolated from this plant for the first time except for compounds 4, 5 and 13.

OBJECTIVETo observe the effect of Tangke Decoction (TD) on the expression of TGF-beta1/Smad4 of rats with early diabetes and to explore the effect and mechanism of TD against the renal injury induced by diabetes.

METHODSSD rats were randomly divided into the normal control group (n = 12), the model group (n = 10), the Chinese herbs prevented group (n =10), the Chinese herbs treated group (n = 10), and the Western medicine control group (n = 10). TD (18 mg/kg) was given by gastrogavage to rats in the Chinese herbs prevented group immediately after successful modeling for 12 weeks, once daily. At the 4th week of successful modeling, rats in the rest 4 groups were administered by gastrogavage. Equal volume of normal saline was given to rats in the model group and the normal control group. Benazepril suspension (1 mg/kg) was administered by gastrogavage to rats in the Western medicine control group for 8 weeks, once daily. TD (18 mg/kg) was given by gastrogavage to rats in the Chinese herbs treated group for 8 weeks, once daily. The body weight, kidney weight, index of kidney weight, fasting blood sugar, 24 h urinary albumin excretion rate were examined after experiment. The pathological changes of the renal tissue were observed by HE staining, Masson staining, and electron microscope. The expression of renal transforming growth factor-beta1, (TGF-beta1) and Smad4 were detected using immunohistochemical assay.

RESULTSCompared with the normal control group, the body weight of rats decreased significantly; the kidney weight, index of kidney weight, blood sugar, 24 h urinary protein excretion, the urinary albumin excretion rate,TGF-beta1 and Smad4 expression increased significantly in the model group (all P < 0.01). Compared with the model group, the aforesaid indices were improved in each treatment group with statistical difference (P < 0.05, P < 0.01). Compared with the Western medicine control group, the kidney weight, index of kidney weight, blood sugar, 24 h urinary protein excretion, and the urinary albumin excretion rate were obviously improved in the Chinese herbs prevented group (P < 0.01). The renal pathological changes were most obvious in the model group significantly, but they were improved in all treatment groups.

CONCLUSIONTD could obviously improve the symptoms of diabetes and down-regulate the expression of renal TGF-beta1 and Smad4 of early diabetic nephropathy rats, which suggested that TD had certain preventive effect on early diabetic nephropathy.
