Context: Euphorbia hirta L. has been wildly used for its health benefits. It has been used as a decoction and to treat diarrhea, peptic ulcers, menstrual problems and venereal diseases. Aims: The study aims to investigate the estrogenic effects of E. hirta on ovariectomized (OVX) rats. Methods: The ovariectomized rats were divided into four groups, including those that received the vehicle (1\% v/v Tween 80, p.o.), 17\β-estradiol at a dose of 0.01 mg/kg B.W. and the ethanolic extract of E. hirta at the doses of 100 and 500 mg/kg B.W. These were administered daily for 14 days. Estrogenic activity was determined by analyzing the body, vaginal and uterine weight as well as the uterine and vaginal histopathology characteristics of the estrogen-induced response. Results: At the dose of 500 mg/kg B.W., the plant extract produced a significant increase in vaginal weight when compared with the ovariectomized rats, a slightly increase in the uterine weight and could induce hyperplastic epithelium and endometrial thickness of the vagina. Conclusion: The data in this work suggests that the plant crude extract showed weak estrogenic effects in ovariectomized rats and could be useful for health benefits for vagina atrophy of females during the menopause.

Objectives: This research was carried out for describing, illustrating and treating a new medicinal plant variety in the genus Trichosanthes. Methods: This research was carried out by collecting plant specimens in the Northeastern Thailand. Morphological characters were studied and compared with the closely related taxon and taxonomic literatures. Results: T. tricuspidata subsp. rotundata var. longirachis, was found. This plant is described and illustrated here and treated as a new variety. It differs from the other of T. tricuspidata subsp. rotundata by having the following combination characters: Comparatively stout herbaceous climber up to 20 m long, tendril 3\–5-brached, probract obovate with obvious glands, mature blade unlobed or 3-shallowly lobed with 1-2 short angles, blade not deeply lobed (unlobed blade found in juvenile plants), blade size 5-11 cm diameter and raceme rachis length 10\–130 cm. Its fruits and seeds were used as medicinal parts. Conclusion: Totally, three subspecies and four variety of T. tricuspidata in Thailand have been recorded so far. Important comparative morphological characters with some closely related variety are discussed. The local people used it as medicinal plant.

Context: Bauhinia nakhonphanomensis Chatan. A new species that is endemic to Thailand. Aims: Leaves of B. nakhonphanomensis were extracted and the extract was used in gas chromatography-mass spectrometry (GC-MS) analysis to evaluate the total phenols, total flavonoids and antioxidant activity. Methods: The extract of B. nakhonphanomensis was analyzed by GC-MS. Quantitative analysis for total phenols was done by the Folin-Ciocatteu method and for total flavonoids by the aluminium chloride method. The antioxidant activity of the ethanolic extract was evaluated by the DPPH method. Results: GC-MS analysis revealed the presence of 19 phytochemical constituents. These compounds were identified by comparing their retention times and peak areas with those from the literature and by interpretation of the mass spectra. The major chemical constituents were inositol (48.55 \%), alpha-tocopherol (12.21 \%) and phenol (6.61 \%). Total phenolic content was 48.69\±0.56 mg/100 of Gallic acid equivalent (GE). The total flavonoid contentwas 10539\± 6.14 mg/100 of quercetin equivalent (QE). Antioxidant activity was 17.07\±0.24 \μg/100 of ascorbic acid equivalent antioxidant capacity (AEAC).Conclusion: These findings are the first report and suggest that the rich phytochemical content of B. nakhonphanomensis has good antioxidant activity.
