TL;DR: Phytochemical screening revealed the presence of alkaloid, flavonoid, saponin, terpenoid, steroid and sterols in the extracts of aerial part of Euphorbia hirta.
Abstract: Medicinal plants have biologically compounds which are used for treating various human diseases and also play an important role in curing. Phytochemicals have two categories i.e., primary and secondary constituents. Primary constituents involve chlorophyll, proteins sugar and amino acids whereas secondary constituents contain terpenoids and alkaloids. Due to the presence of these secondary constituents medicinal plants show antifungal, antibacterial and anti-inflammation activities. The present study was designed to investigate the phytochemical screening and antimicrobial activities of Euphorbia hirta extracts. Phytochemical screening revealed the presence of alkaloid, flavonoid, saponin, terpenoid, steroid and sterols in the extracts of aerial part of Euphorbia hirta. Methanol, chloroform and hexane extract of leaf and fruit were tested against Proteus mirabilis, Listeria monocytogenes, Clostridium absonum, Aspergillus niger, Aspergillus fumigates, Arthrographis cuboidea by the agar disc diffusion method.

TL;DR: This study identified the medicinal plants currently used, registered traditional knowledge, and documented the patterns of ailments treated in the indigenous communities of Totonacas.
Abstract: An ethnobotanical study was performed to collect information on the use of medicinal plants in Papantla, Veracruz, Mexico. The area has a high number of endemic species, and the social importance of the medicinal plants in the community is essential for public health and the conservation of traditional knowledge. This study identified the medicinal plants currently used, registered traditional knowledge, and documented the patterns of ailments treated in the indigenous communities of Totonacas. A total of 101 medicinal plants belonging to 51 families were described by 85 local informants. Asteraceae was the family with the highest number of plant species identified by these informants. Plant parts are used to treat several ailments, including venomous bites, gastro-intestinal disorders, infectious diseases and other disorders. Informants reported that the most common plant part used was the leaf tissue (55%), and they also took the herbal remedies orally (72%), and decoctions (38%) as well as infusions (29%) were the forms used to prepare these natural remedies. This study provides documentation of medicinal plants used in the Veracruz area of Mexico. Mexican people are still dependent upon medicinal plants, and in order to avoid their loss, certain measures of conservation for medicinal plants are needed.

TL;DR: The results revealed that phenols, flavonoids saponins and glycosides cyanides were the most abundant phytochemical components in the investigated plants, highlighting the importance of these detected plant varieties as a source of anticancer agents.
Abstract: Medicinal plants have a great role in influencing health all over the world. There are few studies for the phytochemical investigations in medicinal plants were conducted in Saudi Arabia especially in Albaha region in south-western Saudi Arabia. Therefore this study focused on the detection of the phytochemical composition of the most dominant eighteen natural medicinal plant varieties found in Albaha region. Aqueous extracts of the dried aerial parts of these plants were prepared. The phytochemical composition of these extracts was investigated. Also, the antioxidants and anti-cancer activity of these plants' extracts were evaluated. The results revealed that phenols, flavonoids saponins and glycosides cyanides were the most abundant phytochemical components in the investigated plants. Dodonaea viscosa, Solanum incanum, Olea europaea subsp. cuspidata and Aerva javanica were the highest plants in their phytochemical components and their antioxidant capacity. Their antioxidant capacity recorded 38, 32, 22 and 14% increase more than that of the standard (Ascorbic acid) respectively. Also, these plants showed an interesting anticancer effect compared to the other studied plants. Their IC50 against studied cancer cell lines was lower than 20 μg/ml. This low IC50 is an evidence to be a promising anticancer agent for crude extracts. Thus the present study highlighted the importance of these detected plant varieties as a source of anticancer agents. More intensive studies are needed to verify the most effective chemical components in these investigated plants.

TL;DR: A detailed study of four Berberis species, namely B. aristata, B. asiatica,B.
Abstract: Berberis aristata known as “Daruharidra” in Ayurveda is a versatile medicinal plant used singly or in combination with other medicinal plants for treating a variety of ailments like jaundice, enlargement of spleen, leprosy, rheumatism, fever, morning/evening sickness, snakebite, and so forth. A major bioactive marker of this genus is an alkaloid berberine, which is known for its activity against cholera, acute diarrhea, amoebiasis, and latent malaria and for the treatment of oriental sore caused by Leishmania tropica. Although the roots of B. aristata are considered as the official drug (Ayurvedic Pharmacopoeia of India), the study revealed that different species of Berberis, namely. B. asiatica, B. chitria, and B. lycium are also used under the name of Daruharidra in different parts of the country. Detailed physicochemical and phytochemical studies of subjects like total ash, acid insoluble ash, tannins, and total alkaloids were calculated from the shade dried powdered material according to the recommended procedures. Further, heavy metal studies and quantitative estimation of berberine through HPTLC have also been performed as per ICH guidelines. A detailed study of four Berberis species, namely B. aristata, B. asiatica, B. chitria, and B. lycium, which are implicated as Daruharidra and collected from wild and ten commercial samples procured from various important drug markets in India has been carried out, which may be useful to pharmaceutical industries for the authentication of the commercial samples and exploring the possibilities of using other species as a substitute of B. aristata.
