(Family Brassicaceae) is known to possess different pharmacological properties. &lt;strong&gt;Objective: &lt;/strong&gt;The genoprotective role of flavonoids of &lt;em&gt;L. sativum &lt;/em&gt;methanolic seed extract (LSF) against cyclophosphamide (CP)-induced DNA damage, in somatic and germ cells of mice, as well as characterization of the flavonoidal content were carried out in this study. Chromosomal aberration analysis in somatic and germ cells were also included. &lt;strong&gt;Materials and Methods: &lt;/strong&gt;Six mice groups were used for this study. Group 1 served as a negative control. Group 2 received oral LSF (100 mg/kg b.wt.) for 5 consecutive days. Group 3 served as a positive control by receiving a single intraperitoneal (i.p.) CP dose (20 mg/kg b.wt.). The three other groups were orally administered 25, 50 and 100 mg/kg b.wt. LSF, respectively, for 5 consecutive days. On the last day of treatment, the three groups received i.p. injection of CP (20 mg/kg b.wt.). Flavonoids were identified using spectral analysis.&lt;strong&gt; Results: &lt;/strong&gt;LSF inhibited DNA aberrations in mice caused by cyclophosphamide dose dependently in the three groups with significant difference in the two groups that received doses of 50 and 100 mg/kg b.wt. The chromosomal aberrations inhibitory indices were calculated as 18 and 31 in mice somatic cells and 27 and 48 in germ cells, respectively. LSF was found to contain the flavonoids kaempferol, quercetin, kaempferol-3-O-α-L-rhamnopyranoside, kaempferol-3-O-β-D-glucopyranoside, and quercetin-3-O-β-D-galactopyranoside. &lt;strong&gt;Conclusion: &lt;/strong&gt;LSF inhibited the DNA damage induced by CP in somatic and germ cells of mice dose-dependently. The antioxidant properties associated with flavonoids might account for the genoprotective activity.&lt;/p&gt;

Their structures were elucidated by spectroscopic methods including&lt;sup&gt; 1&lt;/sup&gt;HNMR, &lt;sup&gt;13&lt;/sup&gt;CNMR, EI/MS spectrometry and by comparing their data with those reported in the literature. The cytotoxicity was evaluated using MTT assay. The mode of action of the extract was predicted by using Enzyme-linked Immunosorbent Assay Kit for Tubulin beta (TUBb). &lt;strong&gt;Results: &lt;/strong&gt;Eight compounds for the first time from this plant were identified as Palmitic acid (1), Phytol (major) (2), Stigmast-4-en- 3-one (3), mixture of α-amyrin (4) and β–amyrin (5), 1,6,10,14,18,22-Tetracosahexaen-3- ol,2,6,10,15,19,23-hexamethyl (all-E) (6) and mixture of α– amyrin acetate (7) and β-amyrin acetate (8). The extract showed potent cytotoxic activity on MCF-7 breast carcinoma cell line as well as HCT-116 colon carcinoma cell line at different concentrations (100-6.25 ug/ml) with IC&lt;sub&gt;50&lt;/sub&gt; (21.8 ± 0.9) and (40.9 ± 1.3) respectively. Phytol showed potent cytotoxic activity on MCF-7 cell line at different concentrations (100-12.5 ug/ml) with IC&lt;sub&gt;50&lt;/sub&gt; (60 ± 2.4), while it had no cytotoxic effect on HCT-116 cell line. The extract showed significant TUBb polymerization inhibition activity. &lt;strong&gt;Conclusion: &lt;/strong&gt;The extract of aerial parts of &lt;em&gt;Jacquemontia pentantha &lt;/em&gt;(Jacq.) and also phytol compound has cytotoxic activity due to the presence of phytochemicals such as sterols and terpenes.&lt;/p&gt;

Their structures were determined as 3-O-β-D-glucopyranosyl-(1→2)-[α-L-arabinofuranosyl-(1→3)]-βD-glucuronopyranosyl22-OangeloylA1- barrigenol and 3-O-β-D-galactopyranosyl-(1→2)-[α-L-arabinofuranosyl-(1→3)]-β-Dglucuronopyranosyl 22-O-(2-methylbutyroyl)-A1 barrigenol, respectively. The triterpene part 22-O-(2-methyl butyroyl) A1-barrigenol has never been characterized before. The α- glucosidase inhibitory activity of the two saponin mixture was evaluated &lt;em&gt;invitro&lt;/em&gt; and proved to exhibit strong activity with IC&lt;sub&gt;50&lt;/sub&gt; value equals to 13.3 ± 5.0 ppm and IC&lt;sub&gt;90 &lt;/sub&gt;value equals to 21.5 ± 8.0 ppm. &lt;strong&gt;Conclusion: &lt;/strong&gt;Two new saponins were characterized from their mixture and found to exhibit α-glucosidase inhibitory activity.&lt;/p&gt;
