  • Antidiabetic treatment with tubers of Asparagus racemosus (Liliaceae) extract (l00 and 250 mg/kg body weight) for three weeks showed significant reduction in thiobarbituric acid reactive substances (TBARS) and glutathione reductase (GSH-R) in both liver and kidney. The treatment with A. racemosus significantly altered the glutathione (GSH) and GSH-R to be comparable with the control group. A. racemosus and glibenclamide treated rats showed decreased lipid peroxidation that is associated with increased activity of superoxide dismutase (SOD) and Catalase (CAT). The ability of A. racemosus on tissue lipid per oxidation and antioxidant status in diabetic animals has not been studied before. The result of this study thus shows that though, A. racemosus possesses moderate antidiabetic activity, but it exhibits potent antioxidant potential in diabetic conditions.

  • The methanol extract of Asparagus racemosus root was evaluated for its anti-inflammatory activity on carrageenin and serotonin-induced rat hind paw oedema models. The extract (200 and 400 mg/kg) showed maximum inhibition of oedema of 18.6% and 33.7% at 3 h with carrageenin and 22.2% and 40.5% at 5 h with serotonin-induced rat paw oedema respectively. The experimental models tested, where the effect produced by the extract was compared to that of phenylbutazone, a prototype non-steroidal anti-inflammatory drug.

  • An extracellular exoinulinase($2,1-\beta-D$ fructan fructanohydrolase, EC 3.2.1.7), which catalyzes the hydrolysis of inulin into fructose and glucose, was purified 23.5-fold by ethanol precipitation, followed by Sephadex G-100 gel permeation from a cell-free extract of Kluyveromyces marxianus YS-1. The partially purified enzyme exhibited considerable activity between pH 5 to 6, with an optimum pH of 5.5, while it remained stable(100%) for 3 h at the optimum temperature of $50^{\circ}C$. $Mn^{2+}\;and\;Ca^{2+}$ produced a 2A-fold and 1.2-fold enhancement in enzyme activity, whereas $Hg^{2+}\;and\;Ag^{2+}$ completely inhibited the inulinase. A preparation of the partially purified enzyme effectively hydrolyzed inulin, sucrose, and raffinose, yet no activity was found with starch, lactose, and maltose. The enzyme preparation was then successfully used to hydrolyze pure inulin and raw inulin from Asparagus racemosus for the preparation of a high-fructose syrup. In a batch system, the exoinulinase hydrolyzed 84.8% of the pure inulin and 86.7% of the raw Asparagus racemosus inulin, where fructose represented 43.6mg/ml and 41.3mg/ml, respectively.

  • Aims: To evaluate anti-cancer activity of Asparagus racemosus (AR) leaf extract on UOK146, a renal cell carcinoma cell line, and explore its mechanism of action. Materials and Methods: Dried AR leaves were extracted with chloroform and dissolved in DMSO. This extract was applied to UOK146 and cell death was estimated by MTT assay. In addition PRCC-TFE3 fusion transcripts were detected by real time PCR. Results: Extract was found to be cytotoxic with an $IC_{50}$ of 0.9 mg/ml as estimated by dose response curve. Antitumor activity of the permissible doses of the extract was assessed by the down regulation of PRCC-TFE3 fusion transcript (38%) responsible for oncogenicity of the UOK146 cell line. No increment in the BAX, a proapoptotic marker level was observed. Conclusions: Evidence of antiproliferative effect, PRCC-TFE3 fusion transcript inhibition and static BAX level clearly indicate that AR extract provides or elicits an apoptosis independent anticancer effect on RCC cells by some specific mechanism of regulation.

  • An in vitro and in vivo studies were conducted to evaluate the antibacterial efficacy of certain botanicals viz., rhizomes of turmeric (Curcuma longa) and leaves of amla (Phyllanthus emblica), asparagus (Asparagus racemosus), bael (Aegle marmelos), boerhavia (Boerhavia diffusa), garlic (Allium sativum) and basil (Oscimum basicilum) against bacterial pathogens viz., Staphylococcus sp., Bacillus sp. and Klebsiella cloacae, of silkworm, Bombyx mori. Asparagus and basil, amla and boerhavia, basil and bael at concentration of 20, 000 ppm showed higher antibacterial activity against Staphylococcus sp., Bacillus sp., K. cloacae respectively, both in vitro and in vivo studies.

  • Ten numbers of plants, based on their medicinal value, were used to test their efficacy against virosis (caused by cytoplassmic polyhedrosis virus) in tasar silkworm, Antheraea mylitta Drury. in indoor rearing conditions. The aqueous extracts of leaf of Azadirichita indica (neem), Acharanthus aspera, Psoralea corylifolia, Asparagus racemosus, Adhatoda zelanica (Basak), Andrographis paniculata (Kalmegh), Moringa oilephera (sahjan), whole plant of Phyllanthus urinaria (Bhuiamla), Centella asiatica (Veng sag) and Curcuma longa (Haldi powder) in different concentrations were used for containment of virosis in silkworm larvae. The tasar silkworm larvae were orally inoculated with PIBs ($1\times10^6$) of AmCPV in $2^{nd}$ instar and treated with plant extracts in each instar ($2^{rd}$ instar onwards). The mortality due to virosis was recorded during larval period. The plant extracts, irrespective of their concentrations, were found effective in suppressing the virosis where P. urinaria reduced the virosis to 56.90% followed by A. paniculata (53.82%) and least in C. asiatica (5.15%). The lowest pooled larva mortality 36.99% was recorded in the treatment of P. urinaria. Comparatively higher larva mortality 39.91% was observed with the treatment of A. paniculata. The highest larva mortality in treatment was with C. asiatica (81.99%). In treated control larva mortality was 86.50%.
