Capsicum frutescen is known in Sudan, is one of the most commonly used pepper species in cooking and in Sudanese folk medicine. The present study was conducted to investigate antimicrobial (bacteria and fungi) and cytotoxicity (Brine Shrimp Lethality Test) of methanolic extract of Capsicum frutescen (fruits). The extract have been tested in the present study to investigate the in vitro potential effects against Gram positive, Gram negative bacteria and fungi. The selected organisms were Staphylococcus aureus, Escherichia coli, Pseudomonas aeruginosa, Klebsiella pneumonia and Candida albicans using the cup plate agar diffusion method. The methanol extract of Capsicum frutescen (fruits) exhibited inhibitory effects against Escherichia coli with zone of inhibition (23 mm) and Klebsiella pneumonia with zone of inhibition (17 mm). The phytochemical screening revealed the presence of Tannins, Saponin, Alkaloids, Anthroquinoles and Terpenoids. The Cytotoxicity of methanolic extract of Capsicum frutescens was $LD_{50}$ $64.68{\mu}g/ml$. The activity and presence of compounds known to be biologically active are a validation for the use of Capsicum as a food ingredient and as a therapeutic element of traditional medicine.

We investigated whether oral administration with capsicum extract (Capsicum annuum var. cheongyang) would affect the immune system by examining the immune cells of Peyer's patch (PP), a gut associated lymphoid tissue, ex vivo. The mice were orally administrated with capsicum extract (100 mg/kg/day), capsaicin (10 mg/Kg), and the vehicle for four consecutive days, and PPs were isolated from intestines 2 days later. When the PP cells were cultured in the presence of Concanavalin A for 72 hr, the levels of cytokines, including IL-2 and IFN-${\gamma]$, were dramatically increased, while the levels of IL-4 remained unchanged compared with the control. Data from the FACS analysis of PP cells indicated that capsicum extract significantly increased the number of CD3+ and CD4+ T cells as well as CD 19+ B cells compared with the control but not CD11b+ cells. Furthermore, the percentages of IL-2+ /CD4+ cells and IFN-${\gamma}+$/CD4+ were greatly increased. These data suggested that oraladministration with capsicum extract might activate the CD4+ T cells leading to cytokine production as well as CD19+ B cells in Peyer's patches. As such, capsicum extract might have potential as an immune modulating agent.

This study was conducted to investigate the effects of fermented capsicum and a capsicum product on lipid metabolism. Fermented capsicum was prepared from red pepper puree tov three months. After 9() days of fermentation, capsaicin and dihydrocapsaicin concentrations were reduced from 24.7 and 14.7 g/mL to 15.5 and 6.45 g/mL, respectively. The capsicum product was prepared from the fermented capsicum mixed with prune extract, green tea extract, neroli extract and oligo-saccharide. Thirty-two male Sprague-Dawley rats were as- signed to four dietary groups (control, high-fat control (BE-control), high-fat-fermented capsicum (HF-S-1), high- fat-capsicum product (HF-S-2)). Plasma and hepatic lipid profiles were examined after three weeks of experimental diet. Food intakes were significantly lower in the HF-S-1 and HF-S-2 groups compared to the control group (p<0.05). The weight of perirenal fat pads was lowest in animals on the control diet (low-fat) and highest in high-fat control diet. The addition of fermented capsicum to high fat diets, HF-S-1 and HE-S-2 groups, resulted in significantly lower fat pad weights compared with the HF-control group. Both fermented capsicum (HF-S-1) and the capsicum product (HF-S-2) groups had lower plasma TG levels, atherogenic-index, and liver TG levels than the BE-control group (p <0.05). Liver TC levels were significantly lower in the HF-S-2 group than the HF-control group. The results demonstrate a hypolipidemic effect of fermented capsicum and the fermented cap-sicum product.

The investigation is involved with the effect of Capsicum component on the drug metabolism. To investigate the effects of Capsicum component on, in vivo, drug metabolism in rat, Capsicum acetone extract was given intraperitoneally to mice or rats. The duration of loss of righting reflex was determined as hexobarbital sleeping time in mice. Plasma hexobarbital concentration was also measured by Brodie's method. The rats were pretreated with Capsicum extract acutely or chronically. As the results, hexobarbital sleeping time and plasma hexobarbital concentration were increased by 31.2% and 12.3% in acute study, whereas were decreased by 27.5% and 23.0% in chronic study. An attempt was made to determine if there were any influences on enzyme activities in rats pretreated with Capsicum extract chronically. Microsomal fraction was isolated from rat liver and quantity of cytochrome $P_{450}$ and $b_5$ in the microsomal fraction were determined by Omura's method. It was found that the quantity of cytochome $P_{450}$ was increased by 22.4%. The results suggest that microsomal drug metabolizing enzyme may be induced by chronic administration of Capsicum component, whereas it may be inhibited by acute administration of Capsicum component.

Capsicum annuum belongs to the Solanaceae family, crops of which are extensively cultivated worldwide. It is a food source containing various nutrients and vitamins and also serves as a medicine for treating ailments. The burning feeling experienced while consuming Capsicum fruits is due to the presence of capsaicinoids, particularly capsaicin and dihydrocapsaicin. This study aimed to assess the content of these two compounds in 34 varieties of capsicum and paprika. High-performance liquid chromatography with a gradient elution system and a reverse-phase YMC Pack-Pro column with UV detection at 280 nm was employed. The results revealed that, among the 34 samples, only six samples (samples 1, 15, 20, 29, 32, and 34) contained capsaicin and dihydrocapsaicin, and their highest contents were found in sample 1 - variety name: Sungil-c (capsaicin: 3.42 mg/g extract, dihydrocapsaicin: 1.20 mg/g extract). These findings suggest that the content of these two compounds is attributed to the variety and is influenced by geographical location and environmental factors. Additionally, this study provides a basis for establishing a C. annuum variety with high capsaicin and dihydrocapsaicin contents.

A pot experiment was conducted to assess the effects of red pepper (Capsicum annuum) and coriander (Coriandrum sativum) on seedling growth of wheat (Triticum aestivum). The aqueous extracts treatment of red pepper and coriander showed a significant (p < 0.05) reduction in root, shoot and seedling length, number of leaves and seedling dry weight of wheat (T. aestivum) as compared to control. The inhibitory different effect on growth of wheat (T. aestivum) was directly proportional to the increasing concentration (1, 2, 3, 4 and 5%) of aqueous extracts of red pepper and coriander as compared to control treatment (0%). The root, shoot, seedling length and number of leaves of T. aestivum significantly p < 0.05 decreased at 5% concentration of red pepper as compared to control. The root, shoot and seedling growth of T. aestivum was also significantly reduced at 1, 2, 3, 4 and 5% concentration of coriander as compared to control. The root, shoot and leaves dry weight of T. aestivum at 5% coriander extract treatment concentration decreased as compared to control. The tolerance in seedlings of T. aestivum to red pepper and coriander extract treatment was dose dependent as compared to control. The seedlings of T. aestivum showed low percentage of tolerance to pepper extract treatment than coriander extract treatment.
