Experimental results reveal that 2, 4-D either alone or in combination with kinetin supplemented in MS medium showed significant initiation of callus from leaf explants than stem. Growth hormones, pH, light, and carbon source influence anthocyanin synthesis. Maximum callus induction was noticed with 2.5 mg/L N6-benzyladenine (BA) + 2 mg/L 2, 4-dichlorophenoxyacetic acid (2, 4-D) (98.9%). Fresh and dry weight of the calli were i.e., 1.9 &amp;plusmn; 0.04 and 0.45 &amp;plusmn; 0. 03 g respectively. Optimal response was seen with light on MS medium contain 4% glucose + 2.5 mg/L BA and 2 mg/L 2, 4-D at pH 3.5 yielded 2.8 mg /g of anthocyanins. Suspension culture medium fortified with 2, 4-D (2.5 mg/L) + BA (2 mg/L) at pH 5.0 induced anthocyanin production at pH 4.4 &amp;ndash; 4.6. HCl-ethanol extraction for 90 min yielded the maximum anthocyanin content. Fractionation of anthocyanin using HPLC coupled with mass spectrometry revealed 07 fractions such as acylated cyanidins, two peonidins, cyanidin 3-p-coumaroyl and feruloyl diglucoside-5-glucosides. In the search of novel therapeutic drugs against cancer, cytotoxicity effect of &lt;em&gt;B.retusa&lt;/em&gt; anthocyanin extracts on human oral squamous cell carcinoma (SCC4, SCC9 and SCC25) cells using cell adhesion and cell viability assay was carried. The morphological alterations in SCCs cells after treatment with &lt;em&gt;B.retusa&lt;/em&gt; anthocyanin includes nuclear condensation, fragmentation and apoptotic cells as revealed by Hoechst stain. Flow cytometry showed arresting of SCC25 cells mostly in the G0/G1 and S-G2/M stages with a concomitant up regulation of sub-G1 fraction, indicating cell death by apoptosis. Apoptosis was further substantiated by the activation of caspase-3 expression in the SCC25 cells treated with &lt;em&gt;B.retusa&lt;/em&gt; anthocyanin. Thus, it is possible to suggest that &lt;em&gt;B.retusa&lt;/em&gt; anthocyanin cause apoptosis of SCCs and warrant further investigation using animal models.&lt;/p&gt;</style></abstract><issue><style face="normal" font="default" size="100%">3</style></issue><work-type><style face="normal" font="default" size="100%">Original Article</style></work-type><section><style face="normal" font="default" size="100%">559</style></section><auth-address><style face="normal" font="default" size="100%">&lt;p style=&quot;text-align: justify;&quot;&gt;&lt;strong&gt;Aswathy Jayasree Madanakumar&lt;sup&gt;1&lt;/sup&gt;, Bosco Lawarence&lt;sup&gt;2&lt;/sup&gt;, Manoj GS&lt;sup&gt;3&lt;/sup&gt;,Murugan Kumaraswamy&lt;sup&gt;1*&lt;/sup&gt; &lt;/strong&gt;&lt;/p&gt;

Unfortunately, the cytotoxicity properties of most chemotherapy drug are nonspecific and therefore do not distinguish between normal healthy cells and tumor cells, these events have led to inappropriate and toxic therapeutic agents with a wide range of side effects. However, several experimental and epidemiological studies have suggested that fruits and vegetables are associated with low risk of various types of cancer. Anthocyanins are natural pigments that provide intense purple to red color in plants. Anthocyanin possess the ability to inhibit oxidative stress and to induce apoptosis in malignant cells, thus may prevent carcinogenesis. &lt;strong&gt;Methods:&lt;/strong&gt; Antiproliferative properties of purified anthocyanin extract from elicited cell suspension cultures of &lt;em&gt;Begonia malabarica&lt;/em&gt; and &lt;em&gt;Begonia rex-cultorum&lt;/em&gt; &amp;lsquo;Baby rainbow&amp;rsquo; was investigated in terms of MTT assay. Anthocyanin extracts were tested for their ability to inhibit the growth of HT29 (colon cancer cells), MG63 (Osteosarcoma), HeLa (Cervical cancer cells) and L929 (Mouse Fibroblast L929) cell lines. &lt;strong&gt;Results:&lt;/strong&gt; Cell viability decreased in a dose dependent manner in all the considered cell lines treated with anthocyanin extracts. The extract of &lt;em&gt;Begonia rex-cultorum&lt;/em&gt; &amp;lsquo;Baby rainbow&amp;rsquo; exhibited significant cytotoxic activity against all tumor cell lines than &lt;em&gt;Begonia malabarica&lt;/em&gt; extract. &lt;em&gt;Begonia malabarica&lt;/em&gt; and &lt;em&gt;Begonia rex-cultorum&lt;/em&gt; &amp;lsquo;Baby rainbow&amp;rsquo; anthocyanin extract exhibited the highest cytotoxicity towards HT29 and HeLa cell lines respectively. But, MG63 resulted in comparatively higher percentage of viability of cell lines at the same concentrations. The anthocyanin extract produced significant morphological alterations on cell lines in culture. Meanwhile, the extracts showed poor cytotoxicity against the normal cell line. &lt;strong&gt;Conclusion:&lt;/strong&gt; The morphological alteration of the treated cancer cells presented clear evidence of significant cytotoxicity of anthocyanin extracts of both Begonias in all the three cell lines. Thus, anthocyanin may act as chemopreventive agents for various cancer cell lines.&lt;/p&gt;

Many phytochemicals are reported from the plant as potential source of crude drug. &lt;strong&gt;Materials and Methods:&lt;/strong&gt; An efficient and simple reproducible protocol was developed for callus production using leaf explants of &lt;em&gt;C. pulcherrima&lt;/em&gt;. The combination of 2, 4-D, kin and BA, was used for the callus induction. Subsequently, cell suspension culture and quercetin synthesis from &lt;em&gt;in vitro&lt;/em&gt; callus was attempted. Role of effect of elicitors (Sucrose, ABA and salicylic acid) in cell suspension culture was carried in MS medium containing 2,4-D + BA + kinetin. Flavonoids was purified, fractionated by HPLC-DAD and NMR.&lt;strong&gt; Results:&lt;/strong&gt; 2, 4-D (2.5 mg/L), BA (2.5 mg/L) + kin (1 mg/mL) was effective for maximum callus induction from leaf explants. Significant cell suspension culture was noticed with liquid MS medium containing 2,4-D (2 mg/L)+ BA (1mg/L)+ kinetin (1.5 mg/L). Sucrose, ABA and salicylic acid (SA) at different concentrations influenced cell biomass and quercetin accumulation. The addition of ABA/SA along with sucrose was found to have no remarkable effect on cell biomass and also quercetin synthesis. However, cells cultured in the medium fortified with 45 g/L sucrose without ABA/ SA showed the highest quercetin content (16.5 mg/g). Flavonoids was purified, fractionated by HPLC-DAD and NMR revealed the presence of 9 components such as quercetin, isoquercetin, quercetrin, rutin, quercetin 3-O-&amp;beta;-D-xyloside, quercetin 3-Oarabinopyranoside, quercetin 3-O- &amp;alpha;-arabinopyranosyl (1&amp;rarr;2) &amp;beta;-galactopyranoside, isorhamnetin 3-O-rutinoside and an unknown compound. &lt;strong&gt;Conclusion:&lt;/strong&gt; &lt;em&gt;C. pulcherima&lt;/em&gt; reveals significant synthesis of quercetin. Quercetin content recorded in cell suspension culture was significantly higher compared with &lt;em&gt;in vivo&lt;/em&gt; plants grown in fields and the compounds were identified by NMR.&lt;/p&gt;</style></abstract><issue><style face="normal" font="default" size="100%">6s</style></issue><work-type><style face="normal" font="default" size="100%">Original Article</style></work-type><section><style face="normal" font="default" size="100%">s44</style></section><auth-address><style face="normal" font="default" size="100%">&lt;p style=&quot;text-align: justify;&quot;&gt;&lt;strong&gt;Aswathy Jayasree Madanakumar, Greeshma Murukan, Bosco Lawarence, Murugan Kumaraswamy* &lt;/strong&gt;&lt;/p&gt;
