Abstract Seven flavonoids isolated from chloroform , ethyl acetate and butanol extracts, obtained from the aerial parts of Retama sphaerocarpa, have been assessed for cytotoxic activity against three human cancer cell lines: TK-10 (renal adenocarcinom a), MCF-7 (breast adenocarcinom a) and UACC-62 (m elanom a), using the SRB assay. All of them , extracts and flavonoids, were actives in, at least, one of the three cell lines at the recom m ended N ational C ancer Institute doses. They produce a d ose-dependent inhibition of cell grow th at concentrations in the 10-6-10-4 ᴍ and 25 -250 μg/ml range for the flavonoids and extracts respectively, being the flavonol rhamnazin the most cytotoxic.

Aims: Apocynaceae family is the 5th largest medicinal plant family rich in potent secondary metabolites such as Alkaloids, Cardiac glycosides,Terpenoids, irridoid/secoirridoids, flavonoids and Phenolic contents. The present study was aimed to evaluate and compare in-vitroantiproliferative activity of three plants of this family.Methods: Aerial parts of Carissa carandas Linn. (C), Nerium indicum Mill. (N) and Wrightia tinctoria RBr. (W), were collected and dried. Thepowdered drugs were extracted in Ethanol (1), 60% Ethanol (2) and Water (3). Estimation of Phytoconstituents performed using standardmethods. In-vitro cytotoxic activity performed using Sulphorhodamine B (SRB) assay in HepG2, HT29 and SKOV3 human cancer cell lines takingAdriamycin (ADR) as standard. For extracts, GI50 value ≤ 20μg/ml was considered to demonstrate activity.Results: For HepG2 cell line graphs and photomicrographs showed GI50 value as ADR=39.79, C1=2.5, N2=66.3, N3<10 and C2=C3= N1=W1-3>80. Also TGI for C1>80. The extracts, C1, C2, N1, N2, and N3 were found to possess activity against HepG2.These extracts were screened onHT 29 and SKOV3cell lines. The GI50 value observed was<10 for C1, N2, N3 and ADR in HT 29 and <10 for N3 and ADR in SK OV3 cell lines.Thus it was found that aqueous extract of Nerium indicum (N3) and Ethanolic extract of Carissa carandas (C1) were most cytotoxic extractsagainst all three cell lines.Conclusions: our study establishes that Apocynaceae family plants could be an important anticancer lead and could serve as Botanical drug forneoplasia.Keywords: Apocynaceae, SRB Assay, Phytoconstituents, Anticancer drug screening models, Hep G2, HT 29, SK-OV3, HCC.

Three new oleanane saponins (1–3), together with four known ones (4–7), were isolated from the aerial parts of Polyscias guilfoylei. Their structures were elucidated by 1D and 2D NMR experiments, including 1D TOCSY, DQF-COSY, ROESY, HSQC, and HMBC spectroscopy, as well as ESIMS analysis. The antiproliferative activity of all compounds was evaluated using three murine and human cancer cell lines; J774.A1, HEK-293, and WEHI-164. All the compounds were inactive except for 3β- O-[β-D-glucopyranosyl-(1→2)-α-L-arabinopyranosyl]-echinocystic acid 28-[ O-β-D-glucopyranosyl-(1→6) O-β-D-glucopyranosyl] ester (3), which was active against all the cell lines.

Zanthoxylum nitidum (Roxb.) DC (Rutaceae) is a traditional medicine used for the treatment of various diseases like toothache, gingivitis, fever, colic vomiting, diarrhea, and cholera. Three new alkaloids, zanthocadinanine C (1), 7-methoxy-8-demethoxynitidine (2), and zanthonitiside I (3) were isolated from the stems and twigs of Z. nitidum. Their structures were determined on the basis of extensive spectroscopic, including 1-dimensional and 2-dimensional nuclear magnetic resonance and mass spectroscopy data. Compounds 1–3 were evaluated for cytotoxic activity against 5 human cancer cell lines, KB, MCF-7, LNCaP, HepG-2, and LU-1. Compound 2 showed significant cytotoxic activity against all tested human cancer cell lines with IC50 values ranging from 10.3 to 12.6 µM.

To obtain diterpene glycosides from an aqueous extract of the aerial parts of Isodon henryi and further investigate their cytotoxicities, in this study, a total of seven compounds were isolated, including six ent-kaurane diterpene glycosides (1–6) and one diterpene aglycon (7). Among the seven ent-kaurane diterpenes obtained, four were novel compounds, including ent-7,20-epoxy- kaur-16-en-1α,6β,7β,15β-tetrahydroxyl-11-O-β-d-glucopyranoside (1), ent-7,20-epoxy-kaur-16-en- 6β,7β,14β,15β-tetrahydroxyl-1-O-β-d-glucopyranoside (2), ent-7,20-epoxy-kaur-16-en-6β,7β,15β- trihydroxyl-1-O-β-d-glucopyranoside (3), and ent-7,20-epoxy-kaur-16-en-7β,11β,14α,15β-tetrahydr- oxyl-6-O-β-d-glucopyranoside (4), and three were isolated from this plant for the first time (5–7). Their structures were elucidated by utilizing spectroscopic methods and electronic circular dichroism analyses. Furthermore, the cytotoxicities of all seven compounds were investigated in four human cancer cell lines, including A2780, BGC-823, HCT-116, and HepG2. The IC50 values of these diterpenes ranged from 0.18 to 2.44 mM in the tested cell lines. In addition, the structure–cytotoxicity relationship of diterpene glycosides was also evaluated to study the effect of glycosylation on the cytotoxicity of diterpene compounds.
