    CYTOTOXICITY AND ANTI-PROLIFERATIVE STUDIES OF Crinum Jagus L. (Amaryllidaceae) BULB EXTRACT
    (Bima Journal of Science and Technology, 2020-07) Salawu, Kayode Muritala; Atunwa, Soliu Abiola; Eniayewu, Oluwasegun Ibrahim
    Crinum jagus is a flowering plant, commonly called poison bulb. Traditionally, the bulb extract is used in the treatment of several ailments including cancer. Cancer is a global cause of death characterized by abnormal cell proliferation. This research thus aimed to identify secondary metabolites present in the crude extract of C. jagus and evaluate its cytotoxic and antiproliferative activities using bench top assays. Whole C. jagus bulb was collected, air-dried under the shade and extracted into distilled methanol. The extract was concentrated in vacuum and subjected to; phytochemical analysis, brine shrimp lethality (BSL) assay, Sorghum bicolor radical and Allium cepa root growth inhibitory assays. Data obtained was analyzed by Graphpad prism version 6.0. The whole bulb on extraction had a percentage yield of 12.15 % w/w. The phytochemical content of the extract includes alkaloids, flavonoids, tannins and some glycosides. The extract demonstrated concentration dependent brine shrimp lethality (LC50 of 65.62±0.74 μg/mL), Sorghum bicolor radical growth inhibition (IC50 = 5.36±3.21μg/mL) and significant Allium cepa root growth inhibition comparative to cyclophosphamide (a standard anticancer drug). The extract was found to be rich in secondary metabolites which elicited significant cytotoxicity and antiproliferative activities. This is the first report of antiproliferative activity of C. jagus bulb extract. Hence, this study justifies the traditional use of the bulb in the treatment of cancer.

    Evaluation of anti nociceptive and anti inflammatory activities of leaf extract of Turraea vogelli Hook. f. ex. Benth

    Abstract : The leaf extract of Turraea vogelii Hook. f. ex. Benth . is used in ethnomedicine for the management of pain and inflammation. Anti nociceptive activity was determined using acetic acid induced mouse writhing model. The anti inflammatory activity was investigated using in vitro bovine serum albumin (BSA) denat uration assay and BSA induced hind paw edema in rats. The extract (125 500 mg/kg) administered via the oral route produced a significant ( p <0.005) inhibition of acetic acid induced writhes. The percent inhibition of writhes for extract (500 mg/kg) and dicl ofenac (1 0 mg/kg) was 53.3 and 59.5% respectively. The methanol extract (10 6 1.0 µg /mL) inhibited protein denaturation with IC 50 values of ( 1.06 × 10 3 µg/mL and 2.58 × 10 3 µg/mL) for extract and diclofenac respectively. Furthermore, the leaf extract (62. 5 mg/kg) significantly (p<0.05) inhibited BSA induced paw edema in rats. The methanol leaf extract of T. vogelii has anti nociceptive and anti inflammatory activities. These findings justify the use of the plant in traditional medicine for the management o f pain and inflammation.

    Phytochemical, Analgesic and Anti-inflammatory Analysis of the Ethyl acetate Fraction of Paullinia pinata Leaf L. (Sapindaceae).
    (Faculty of Pharmaceutical Sciences, University of Ilorin, Ilorin., 2018) Aiyelero, Oyeronke Medinat; Salawu, Kayode Muritala; Yaro, Abdullahi Hamza; Enape, Ocholi Joseph; Usman, Shukurat Olasumbo
    Paullinia pinnata(Sapindaceae) is commonly called sweet gum (English). Traditionally various parts of P. pinnata is used in the management of various diseases including chronic arthritis rheumatic pain. Phytochemical investigation of the ethyl acetate fraction of P. Pinnata leaf showed the presence of flavonoids, saponins, anthraquinone, steroidal terpenoids and carbohydrates only and it was also observed to be non-toxic with LD50 of 1264.9 mg/kg. The fraction displayed significant analgesic activity (21.45, 35.62 and 92.70 % inhibition at 75, 150 and 300 mg/kg body weight respectively) in the formalin induced pain model, whereas ketoprofen had a 28.32 % inhibition of pain. In acetic acid induced writhing model the fraction also displayed significant analgesic activity between 70.03 to 100 % inhibition of the contraction of the abdominal muscle and stretching of the hind limbs at a dose of 75 to 300 mg/kg body weight respectively, where ketoprofen had a 76.60 % inhibition. The fraction had significant anti-inflammatory activity in carrageenan induced paw oedema model with maximum activity up to three hours (60.0 % at first hour, 47.47 % at second hour, 65.38 % at third hour and 63 % at fourth hour) at a dose of 150 mg/kg body weight. The ethyl acetate fraction of P. Pinnata leaf poses significant analgesic and anti-inflammatory activities.
