Momordica species (Family Cucurbitaceae) are cultivated throughout the world for their edible fruits, leaves, shoots and seeds. Among the species of the genus Momordica, there are three selected species that are used as vegetable, and for medicinal purposes, Momordica charantia L (Bitter melon), Momordica foetida Schumach (Bitter cucumber) and Momordica balsamina L (African pumpkin). The fruits and leaves of these Momordica species are rich in primary and secondary metabolites such as proteins, fibers, minerals (calcium, iron, magnesium, zinc), β-carotene, foliate, ascorbic acid, among others. The extracts from Momordica species are used for the treatment of a variety of diseases and ailments in traditional medicine. Momordica species extracts are reputed to possess anti-diabetic, anti-microbial, anthelmintic bioactivity, abortifacient, anti-bacterial, anti-viral, and play chemo-preventive functions. In this review we summarize the biochemical, nutritional, and medicinal values of three Momordica species (M. charantia, M. foetida and M. balsamina) as promising and innovative sources of natural bioactive compounds for future pharmaceutical usage.

The Kalanchoe genus (syn. Bryophyllum), family Crassulaceae, comprises 125 species, most of them native to Madagascar. The great importance of several of these species for the traditional medicine in several regions of the World, esspecially India, Africa, China and Brazil, stimulated research programs into these plants from both a pharmacological and chemical point of view. The present review focuses on the main results obtained during the last decade on the secondary metabolites isolated from these species – endowed or not with a specific biological profile – with emphasis on flavonoids. The distribution of these molecules in the genus will be summarized and special attention will be given to K. brasiliensis and K. pinnata, two species well-known for healing inflammatory and infectious processes. Ornamental Kalanchoe species are also discussed as a potential source of bioactive compounds. This review covers the period 1970–2008.

Background. Representatives of the genus Allium L. are valuable food and medicinal plants that have long been used for nutrition and human health. Modern research has proved their high biological activity. Earlier, we investigated the aboveground organs of a number of wild onion species in the consumer ripeness phase. Higher content of secondary metabolites has been observed in the hemiephemeroid species A. aflatunense B. Fedtsch., A. microdictyon Prokh., and A. rosenbachianum Regel. The aim of this work was to determine the content of bioactive compounds in the green biomass of Allium species during flowering.Materials and methods. We studied the freshly harvested raw materials – leaves and flower scapes. Dry matter content was measured by drying 1 g of raw material at 100–105°C to constant weight. The amounts of phenolic compounds, pectic substances, total sugars and carotenoids were assessed spectrophotometrically using the SF-56 (Russia) and SF Agilent 8453 (USA) instruments, and ascorbic acid was measured by the titrimetric method. The result was taken as an average of three measurements for each indicator calculated on absolute dry weight of raw material (except ascorbic acid).Results and conclusions. The green biomass of Allium species was found to contain 8,2–16,2% of dry matter; 4,5–12,0% of phenolics (catechins, flavonols and tannins); 6,9–32,4% of total sugars; 9,5–12,6% of pectic compounds (pectins and protopectins); 20,8–102,5 mg% of carotenoids, and 38,0–197,7 mg% of ascorbic acid (wet weight). A significant range of variation in the content of secondary metabolites was due to the species’ characteristics and weather conditions of the growing season. A. microdictyon had a higher content of dry matter, flavonols and tannins, whereas A. aflatunense and A. rosenbachianum were rich in ascorbic acid and sugars. The findings testify to the prospects of using Allium spp. as a source of bioactive compounds.

Curcuma is a genus of family Zingiberaceae. Its rhizomes, as well as leaves, have long been used in the traditional medicine. This research aimed to examine the morphological and anatomical structure as well as the primary and secondary metabolites of Curcuma aeruginosa Roxb, Curcuma longa L, and Curcuma heyneana Valeton & Zijp. The Anatomical structure, histochemical test and secretory cell density were observed microscopically. The Histochemical test consisted of amilum, protein, lipid, tanin, alkaloid dan flavonoid tests. Observation of anatomical structures of the of rhizome showed that starch grains has a medium size and shape of starch was oval. Rhizomes of Curcuma longa and C. aeruginosa had a positive correlation for starch, protein, lipids, alkaloids, flavonoids and tannins. C. heyneana has the highest density value on protein while C. longa has the highest density value on lipids, alkaloids, flavonoids and tannins.

Premna serratifolia known as bebuas has long been used by Malay comunity for both food and traditional medicine. The most notable advantage of this plant is to heal woman after childbirth and to raise the notion that contains anti-inflammatory bioactive compounds. In this study, the hexane extract of bebuas was only contained steroids. Meanwhile the ethanol extract contained various secondary metabolites such as phenolics, alkaloids, flavonoids, steroids and saponins. The ethanol extract was further separated since the targeted compound isolate was an alkaloid. The isolate obtained was a yellow crystal which transformed to yellow oil after being exposed to air. The anti-inflammatory evaluation of the compound gave a result with a strong activity with ED50 = 4.06 mg/KgBW. Characterization by UV-Vis and FT-IR showed that the isolate’s spectra pattern had similarities with bufotenine. It revealed that the isolate shared the same basic skeleton with the bufotenine, especially the indole skeleton. Furthermore, it also shared the same physical form with bufotenine. These evidences strengthened the assumption that the isolate was an indole alkaloid.
